🚀 Enhancements#

Allow user to change rel_tolerance in to_grid_time function (!1102 by @Robert Sokolewicz)

0.21.1 (2024-08-16)#

Release highlights#

In Qblox backend, option to allow NCO operations to not conform to NCO timing constraints (!1058)#

In some cases it is required that NCO operation be allowed on the 1 ns timegrid instead of the NCO 4 ns timegrid. In this case, the user can set the hardware option allow_off_grid_nco_ops to True. (By default, the compiler acts as if it was False.)

hardware_compilation_cfg = {
    "config_type": "quantify_scheduler.backends.qblox_backend.QbloxHardwareCompilationConfig",
    ...
    "allow_off_grid_nco_ops": True,
    ...
}

Documentation update for Timetag, TimetagTrace and Trace protocols on the QTM (!1046)#

Tutorial for the Timetag, TimetagTrace and Trace for QTM has been moved to a dedicated place. For these acquisition protocols, the reference pages adds additional info: detailed list of options for the parameters, and which protocols and bin modes are supported on which Qblox devices.

Performance improvements for compilation for schedules with loops and acquisitions (!1060)#

For schedules with loops and acquisitions, the compilation time can improve as much as 70 %. It is thanks to caching resource validation and removing some unnecessary checks for stitched pulses.

Release highlights#

Insert LatchReset only on necessary portclocks and remove overlap check (!991)#

This change allows the user to schedule operations in parallel to ConditionalReset.

Changes to NV center backend such that Rxy gates use Hermite Pulse (!1009)#

Rxy gates that are used by the NV center backend will now use Hermite pulses instead of DRAG pulses.

Make NV center hardware configs compatible with new-style compilation configs, which includes defining a OpticalModulator hardware description (!966)#

With the development of the new style hardware configuration, we now also support NV centers. See our migration guide for more information.

New acquisition protocols: LongTimeTrace, TimetagTrace and Timetag#

The new LongTimeTrace protocol allows you to perform long traces that consist of repeated SSBIntegrationComplex measurements. It is practical for spin qubit backends.

For the Qblox Qubit Timetag Module (QTM), we introduce a new acquisition protocol, the TimetagTrace. This acquisition is similar to the normal Trace acquisition protocol, but will return a sequence of time tags when the recorded voltage crossed a threshold. The Timetag protocol on the othe other hand will return the first time tag where the voltage crossed a threshold. See tutorial:Acquisitions and our reference guide for more information.

Passing device parameters to gates (!1018, !1039)#

It is now possible to override the default device parameters on the gate level. For example

schedule.add(Measure("q0", acq_duration=32e-6))

will schedule a Measure gate, but when compiled the acquisition duration will be equal to 32.000 ns, instead of the default (e.g. q0.measure.acq_duration). Additionally, we now also allow to pass frequency arguments to the Measure gate:

Measure(qubit="q0", freq=5e9)

which will set the NCO frequency to 5e9 Hz while the Measure operation is executed, and then reset it back to the default.

New supported qubit backend: spins (!1015)#

Quantify now supports spin qubits as a backend, via the new device element BasicSpinElement (based on the Loss-DiVicenzo spin qubit).

Breaking changes#

NV Centers (!966)#

We introduce a temporary convention for the naming of clocks in the hardware configuration. For example, when we have

    "hardware_options": {
        "modulation_frequencies": {
            "qe0:mw-qe0.spec": {
                "interm_freq": 200000000.0,
                "lo_freq": null
            },
            "qe0:optical_control-qe0.ge1": {
            	"interm_freq": 200e6,
            	"lo_freq": null
            },
    ...

the clocks qe0.spec and qe0.ge1 are required to follow the format <qubit>.<tag>. As mentioned, this is only a temporary convention until we finalize our work on redesigning the hardware configuration.

Compilation#

Validating hardware configurations (!1002)#

We are adding validators to various parts of the hardware configuration. The validators may raise a Pydantic ValidationError for existing hardware configurations if they contain faulty, but unused, entries. For example, miss-typing a key in an unused port-clock combination (lofreq rather than lo_freq)

        "hardware_options": {
            "modulation_frequencies": {
                "q0:res-q0.ro": {"lo_freq": LO_FREQ_READOUT},
                "q0:mw-q0.01": {"lo_freq": LO_FREQ_QUBIT},
                "q1:res-q1.ro": {"lofreq": LO_FREQ_READOUT},

will now raise a ValidationError:

 1 validation error for QbloxHardwareCompilationConfig
 hardware_options.modulation_frequencies.`q1:mw-q1.01`.lofreq
 Extra inputs are not permitted [type=extra_forbidden, input_value=3900000000.0, input_type=float]
 For further information visit https://errors.pydantic.dev/2.7/v/extra_forbidden
dispersive_measurement now compiles measurements to a subschedule (997!)#

The factory function quantify_scheduler.operations.measurement_factories.dispersive_measurement now returns a Schedule. Before it returned a single Operation, with different pulses and acquisitions added to Operation.pulse_info and Operation.acq_info, now it returns a Schedule with each Pulse and Acquisition added to it as a separate Operation. This gives us more flexibility with regards to how measurement operations are compiled.

qblox-instruments pinned to 0.14.0#

Trying to import anything from the qblox backend, will raise a DriverVersionError if the qblox-instruments package is not upgraded to 0.14, e.g.

DriverVersionError: The installed Qblox driver (qblox-instruments) version 0.13.0 is not supported by backend.
Please install one of the supported versions (0.14) in order to use this backend.

Deprecation#

Compiling and running schedules using the old-style hardware configuration will now raise a FutureWarning:

FutureWarning: The hardware configuration dictionary is deprecated and will not be supported in quantify-scheduler >= 1.0.0.
Please use a `HardwareCompilationConfig` instead. For more information on how to migrate from old- to new-style hardware
specification, please visit :ref:`sec-hardware-config-migration` in the documentation

Please visit our migration guide for more information.

Bug Fixes#

TriggerCount duration (!976)#

We fixed a bug in TriggerCount where the compiled operation took 4 ns longer than specified by the user.

NCO grid misalignment due to loops and latency corrections (!996)#

We fixed a potential NCO grid time misalignment due to loops and latency corrections. If a loop operation or a latency correction causes an NCO operation to fall outside of a 4 ns grid, it will now raise an NcoOperationTimingError (!996), e.g.

NcoOperationTimingError: The latency correction value of 30 ns for q0:res-q0.ro does not align with the grid time of 4 ns for NCO operations. The latency corrections must adhere to this grid time to ensure proper alignment of all later operations in the schedule.

Support for ClockResources in subschedules#

Defining a ClockResource inside a subschedule no longer leads to a ValueError (!990) during compilation, e.g.

ValueError: Operation 'Measure('q0', acq_channel=None, acq_index=0, acq_protocol="None", bin_mode=None, feedback_trigger_label=None)' contains an unknown clock 'q0.ro'; ensure this resource has been added to the schedule or to the device config.

marker_debug_mode_enable=True no longer prevents Q1ASM generation (!1048)#

Enabling the marker debug mode would sometime prevent Q1ASM to be created during the compilation phase.

0.20.0 (2024-05-01)#

Breaking changes#

The Zhinst backend is now optional, meaning that installing quantify-scheduler no longer installs packages that are required by this backend. For users of the Zhinst backend that want to upgrade to v0.20.0 via pip install --upgrade quantify-scheduler nothing will break, but for fresh environments, you will have to run pip install quantify-scheduler[zhinst].

Release Highlights#

  • sigma is a new parameter that can be passed to the operations GaussPulse and DragPulse which sets the width of the Gaussian envelope in seconds.

  • For the Qblox backend, operations are now allowed to live on a 1 ns time grid, except NCO-related instructions (set_ph, set_ph_delta, reset_ph and set_freq) that still require to start on a 4 ns time grid.

  • quantify-scheduler is now compatible with Python 3.10, 3.11 and 3.12. The current Zhinst backend still requires 3.8 or 3.9.

  • Two new schedules are added to quantify_scheduler.schedules to perform long time-traces: long_time_trace and long_time_trace_with_qubit.

  • The time between uploading and executing Schedules to a Qblox Cluster has reduced, leading to an execution speedup for experiments.

        • For Qblox: "config_type": "quantify_scheduler.backends.qblox_backend.QbloxHardwareCompilationConfig",

        • For Zurich Instruments: "config_type": "quantify_scheduler.backends.zhinst_backend.ZIHardwareCompilationConfig".

  • Operations

    • Modify the parameters of the VoltageOffset operation (!863):

      • Deprecate the duration parameter. The duration of a VoltageOffset is always 0. Using the duration parameter results in a FutureWarning.

      • Make the port parameter non-optional, and the clock parameter by default BasebandClockResource.IDENTITY.

        • Note: This changes the order of the arguments, please check VoltageOffset for the new signature.

    • VoltageOffset and StitchedPulse code moved to Qblox backend (!863):

      • VoltageOffset from quantify_scheduler.operations.pulse_library to quantify_scheduler.backends.qblox.operations.pulse_library.

Release highlights#

  • New features

    • Subschedules & repetition loops

      • A schedule can now be added to a schedule just like an operation.

      • Looping of an operation via new control_flow argument in Schedule.add.

      • Various limitations apply, please consult the documentation: Reference guide: Control flow.

      • Also, currently plotting and timing table is not working:

        • Subschedules: circuit diagram does not work,

        • Repetition loops: not shown in circuit diagram, timing table does not work.

Breaking changes#

  • Deprecation - The deprecated instruction_generated_pulses_enabled Qblox hardware configuration parameter, and the two classes related to it (StitchedSquarePulseStrategy and StaircasePulseStrategy) have been removed. The deprecated code suggestions have been updated. (!811)

  • QuantumDevice - ManualParameter elements and edges have been changed from list to dict. (!813)

    • Before, these were lists with instrument names, so one could do element_name = quantum_device.elements()[0] and edge_name = quantum_device.edges()[0].

    • Now, these are dicts with instrument names as keys and the DeviceElement and Edge instances as values, so one would need to change to element_name = list(quantum_device.elements())[0] and edge_name = list(quantum_device.edges())[0].

    • Also see Tutorial: Operations and Qubits - Device configuration.

Merged branches and closed issues#

Release highlights#

  • Added New tutorials on performing acquisitions:

    • Tutorial: Acquisitions - how to add acquisitions to schedules, and how to retrieve acquisition results using the Instrument Coordinator

    • Tutorial: ScheduleGettable - how to perform acquisitions with ScheduleGettable

  • Fixed sudden_net_zero waveform generation

  • Added Rz, Z and Z90 gate to gate library and BasicTransmonElement

  • Improved pulse diagram, mostly in the matplotlib backend

  • Added new-style validated hardware config: Restructured CompilationConfig by adding HardwareCompilationConfig datastructure that contains HardwareDescription, Connectivity, and HardwareOptions

    • The old-style unvalidated hardware config is still fully supported

    • Currently, the new-style hardware config is being converted to the old-style hardware config before processing by the hardware backends

Breaking changes#

  • Acquisition - Trigger count protocol changes: ScheduleGettable and InstrumentCoordinator return data reconciliation; using counts instead of acq_index as a dimension when BinMode.AVERAGE is used (!703)

  • Instrument Coordinator - Dimension names of the datasets returned by the instrument coordinator have changed. If you used them explicitly in processing, you can fix that by extracting the names dynamically from the dataset. The exact names of the dimensions are not guaranteed to be stable in the future. (!608)

  • Qblox backend - Remove overwriting of IF frequency to None when mix_lo=False (!699)

  • Qblox backend - Compile ShiftClockPhase operation to set_ph_delta + upd_param, extending duration from 0 to 8 ns (!704, #432)

  • Visualization - Large refactor of the pulse diagram, mostly in the matplotlib backend (!664).

    • The matplotlib backend no longer plots 0 V points in between pulses, leading to significant performance improvements in some cases.

    • In both the matplotlib and the plotly backend, lines are now shaded from the line to the x-axis.

    • For the matplotlib backend, an extra keyword argument multiple_subplots (bool) is added. If True, each port used in the schedule gets its own subplot, similar to how it’s done in the plotly backend.

    • In the plotly backend, the time slider at the bottom of the figure has been removed. This was necessary to allow the y-axis of the bottom-most plot to be interactively re-scalable as well.

  • Waveforms - Fix sudden_net_zero waveform generation. Rounding of pulse times will now no longer lead to an incorrect SNZ pulse. I.e., the last sample of the first pulse and the first sample of the second pulse will remain correctly scaled, and the integral correction will have an amplitude such that the integral of the pulse is zero. (!581, #310)

Compatibility info#

0.14.0 (2023-06-02)#

Release highlights#

  • New features

    • Introducing ReferenceMagnitude. A new parameter called has been introduced for pulses, enabling the flexible specification of amplitudes and powers across various orders of magnitude. This parameter allows users to utilize variable attenuations, among other techniques, to precisely control the amplitudes and powers of the pulses. Important note this parameter is not yet implemented for any of the available backends. Future updates are expected to include support for ReferenceMagnitude in the compilation backends.

  • Qblox backend improvements

    • Introducing the MarkerPulse. This feature simplifies the specification of digital pulses with precise timing, facilitating the control of third-party electronics. For more information, see Digital I/O.

    • Improved Compilation Time. The compilation time has been significantly improved, achieving approximately 10 times faster execution. Notably, a 32 times speedup has been observed when running 2-qubit Chevron schedules.

    • Reduced Acquisition Time. The minimum time between acquisitions has been lowered from 1000 ns to 300 ns, enhancing the efficiency of data acquisition.

Breaking changes#

  • Compilation - Introduced new ReferenceMagnitude parameter for pulses to allow specification of amplitudes and powers over different orders of magnitude (using variable attenuations, for example) (!652)

    • Currently, only the user interface is implemented - changes to the backends will be made later (#413)

    • The code is backwards compatible, i.e., all schedules remain valid, but pulse amplitudes are not backwards compatible and will need adjustment / re-calibrating

  • Qblox backend - The compiled offset value in AwgOffsetStrategy is adjusted to match the changes to pulse amplitudes in !652. A pulse with a given amplitude A and a VoltageOffset with offset A will now produce the same voltage at the hardware level (!683).

  • Qblox backend - Lowering the minimum time between acquisitions to 300 ns (!676, #369)

  • Deprecation - Deprecated code that had been scheduled to be removed after version 0.13 has been removed. The deprecated code suggestions have been updated (!679).

  • Visualization - The function quantify_scheduler.waveforms.modulate_wave has been removed as it duplicated quantify_scheduler.helpers.waveforms.modulate_waveform in an incorrect manner (!679).

Merged branches and closed issues#

  • Compilation - Allow to subclass CompiledSchedule in graph compilation (!663).

  • Compilation - Support batched frequencies in schedule resources (!670)

  • Compilation - Move PowerScaling (gain/attenuation) to CompilationConfig.hardware_options (!673)

  • Documentation - Add UML_class_diagrams notebook for visualizing class hierarchies (!653)

  • Gettables - When ScheduleGettable.get() is called and the associated InstrumentCoordinator returns nothing (for example, if the hardware configuration was never set), this will no longer raise a KeyError from the xarray module. Instead, a more helpful error is raised before the data processing (!671).

  • Operations - The function convert_to_numerical_pulse has been added, which can be used to convert StitchedPulse to NumericalPulse (!665).

    • In addition, this function is called in the pulse diagram plotting functions and the ZI LabOne backend to allow resp. plotting and compiling of StitchedPulse.

  • Qblox backend - Raise RuntimeWarning instead of NotImplementedError upon using reference_magnitude parameter (introduced in !652) (!684)

  • Qblox backend - Compilation uses math.isclose instead of numpy.isclose in certain cases to improve compile time (!682)

  • Qblox backend - Add MarkerPulse to pulse library, and implement Qblox backend compilation for this pulse (!628)

  • Qblox backend - Fix bug where LO/IF frequency nan is treated as overconstrained mixer (!690, #423)

Release highlights#

  • This release introduces a new acquisition protocol: NumericalWeightedIntegrationComplex, that allows users perform a weighted integration acquisition.

  • The schedule library now has a new schedule that performs an NCO frequency sweep in a dark ESR experiment on an NV-center.

  • A lot of code that was marked as deprecated has been removed. Please checkout our deprecated code suggestions on how to modify you code to ammend any problems caused by this removal.

  • Many improvements and small bug fixes.

Breaking changes#

  • Deprecation - Deprecated code that had been scheduled to be removed after version 0.12 has been removed. The deprecated code suggestions have been updated (!667).

  • Qblox backend - Deprecate the instruction_generated_pulses_enabled hardware configuration setting, as well as the StitchedSquarePulseStrategy and StaircasePulseStrategy. The newly introduced StitchedPulse, as well as the helper functions in quantify_scheduler.pulse_factories can be used instead. SquarePulses with a duration >1 microsecond (a constant in the Qblox backend) are compiled to AWG offset instructions (!637).
