# Recent interface changes ## 0.20.1: DistortionCorrection - `DistortionCorrection` is now deprecated in favor of `SoftwareDistortionCorrection`. ## 0.18.0: HardwareCompilationConfig and DeviceCompilationConfig - `DeviceCompilationConfig`: The `backend` field was replaced by the `config_type` field. - If you are loading a stored `DeviceCompilationConfig` (instead of relying on the device config generation of the `QuantumDevice`), remove the `"backend"` key. - `HardwareCompilationConfig`: The `backend` field was removed. - Only if you are already using the `HardwareCompilationConfig`, remove the `"backend"` key and add `"config_type": "quantify_scheduler.backends.qblox_backend.QbloxHardwareCompilationConfig"`. ## 0.15.0: HardwareCompilationConfig structure The {class}`~.backends.types.common.HardwareCompilationConfig` datastructure was introduced to structure the information that was previously stored in the hardware configuration dict. The information is now divided into sub-datastructures for the `"hardware_description"`, `"hardware_options"` and `"connectivity"`. For more information, see {ref}`sec-hardware-compilation-config` and {ref}`Cluster (HardwareCompilationConfig) `. ## 0.13.0: Long waveform support The {code}`instruction_generated_pulses_enabled` option is deprecated and will be removed in a future version. Long square pulses, staircase pulses and long ramps can be generated with the newly introduced helper functions {class}`~quantify_scheduler.backends.qblox.operations.pulse_factories.long_square_pulse`, {class}`~quantify_scheduler.backends.qblox.operations.pulse_factories.staircase_pulse` and {class}`~quantify_scheduler.backends.qblox.operations.pulse_factories.long_ramp_pulse`. More complex long waveforms can now also be created from the {class}`~quantify_scheduler.backends.qblox.operations.stitched_pulse.StitchedPulseBuilder`, which generates a {class}`~quantify_scheduler.backends.qblox.operations.stitched_pulse.StitchedPulse`. For more information, see {ref}`Long waveform support `. ## 0.12.0: Marker behavior for RF modules; Custom Qblox downconverter 1. For the Qblox QCM-RF and QRM-RF modules, the marker override QCoDeS parameter `marker_ovr_en` is now always set to `False` before the execution of a schedule. This way, the markers behave as expected, even if they were previously overridden. Please refer to the [qblox-instruments documentation](https://docs.qblox.com/en/main/cluster/qrm_rf.html#marker-output-channels) for more information about the `marker_ovr_en` and `marker_ovr_value` parameters. 2. For deactivating the custom Qblox downconverter, set `downconverter_freq` to `null` (json) or `None` (instead of `0` before). ```{note} Using `downconverter_freq` requires custom Qblox hardware, do not use otherwise. ``` ## 0.11.1: Input attenuation parameter both for input and output Ability to set `input_att` parameter for both `complex_input_0` and `complex_output_0` on QRM-RF. To make sure that you can use the same sequencer for both input and output on QRM-RF with input modulation and input attenuation, you can set `input_att` on either input or output, but not on both in the same module at the same time. ## 0.11.0: Gain and attenuation parameters Ability to set input/output gain/attenuation parameters via the Qblox hardware configuration file. ```{note} `input_gain` introduced in version 0.9.0 is now renamed to `input_gain_`. ``` The following parameters are available per device type: - QRM (baseband) - `input_gain_I` (for `complex_output_0`) or `input_gain_0` (for `real_output_0`) - `input_gain_Q` (for `complex_output_0`) or `input_gain_1` (for `real_output_1`) - QRM-RF - `output_att` (for `complex_output_0`) - `input_att` (for `complex_input_0`) - QCM-RF - `output_att` (for `complex_output_0`) - `output_att` (for `complex_output_1`) See `quantify_scheduler/schemas/examples/qblox_test_mapping.json` for concrete examples. ## 0.8.0: Dynamic Sequencer Allocation The Qblox backend now dynamically allocates sequencers to port-clock combinations as required. This enables the user to target an arbitrary number of port-clock combinations using the same module, as long as they are not being *simultaneously* targeted. Given that Qblox instruments have 6 sequencers, up to 6 port-clock combinations may be simultaneously targeted. This change has introduced a new syntax for the hardware configuration file: 1. We now specify a list of `portclock_configs` instead of sequencers. 2. Furthermore, we moved latency correction to top-level key `latency_corrections` 3. We provide a helper function that may be used to convert from old to new syntax: ```{warning} This helper function has been removed in quantify-scheduler 0.18.0. ``` - `quantify_scheduler.backends.qblox.helpers.convert_hw_config_to_portclock_configs_spec` - Temporarily, this method is called by the Qblox backend before compilation. The old syntax: ```python hardware_cfg = { "backend": "quantify_scheduler.backends.qblox_backend.hardware_compile", "cluster0": { "instrument_type": "Cluster", "ref": "internal", "cluster0_module1: { "instrument_type": "QCM", "complex_output_0": { "lo_name": "lo0", "seq0": { "port": "q0:mw", "clock": "q0.01", "interm_freq": 50e6, "latency_correction" : 4e-9 }, "seq1": { "port": "q1:mw", "clock": "q1.01", "interm_freq": 100e6 } }, "complex_output_1": { "lo_name": "lo1", "seq2": { "port": "q2:mw", "clock": "q2.01", "interm_freq": None } }, }, "lo0": {"instrument_type": "LocalOscillator", "frequency": None, "power": 20}, "lo1": {"instrument_type": "LocalOscillator", "frequency": 7.2e9, "power": 20} } ``` The new syntax: ```python hardware_cfg = { "backend": "quantify_scheduler.backends.qblox_backend.QbloxHardwareCompilationConfig", "latency_corrections": { "q0:mw-q0.01": 4e-9 }, "cluster0": { "instrument_type": "Cluster", "ref": "internal", "cluster0_module1: { "complex_output_0": { "instrument_type": "QCM", "lo_name": "lo0", "portclock_configs": [ { "port": "q0:mw", "clock": "q0.01", "interm_freq": 50e6 }, { "port": "q1:mw", "clock": "q1.01", "interm_freq": 100e6 } ] }, "complex_output_1": { "lo_name": "lo1", "portclock_configs": [ { "port": "q2:mw", "clock": "q2.01", "interm_freq": None } ] } }, "lo0": {"instrument_type": "LocalOscillator", "frequency": None, "power": 20}, "lo1": {"instrument_type": "LocalOscillator", "frequency": 7.2e9, "power": 20} } ```
