Prepare a NV to its negative charge state NV$^-$.

CRCount

Operate ionization and spin pump lasers for charge and resonance counting.
class ChargeReset(*qubits: str)[source]#

Bases: quantify_scheduler.operations.operation.Operation

Prepare a NV to its negative charge state NV$^-$.

Create a new instance of ChargeReset operation that is used to initialize the charge state of an NV center.

Parameters:

qubit – The qubit to charge-reset. NB one or more qubits can be specified, e.g., ChargeReset("qe0"), ChargeReset("qe0", "qe1", "qe2"), etc..

class CRCount(*qubits: str, acq_channel: Hashable | None = None, acq_index: tuple[int, Ellipsis] | int = None, acq_protocol: Literal['Trace', 'TriggerCount', None] = None, bin_mode: quantify_scheduler.enums.BinMode = None)[source]#

Bases: quantify_scheduler.operations.operation.Operation

Operate ionization and spin pump lasers for charge and resonance counting.

Gate level description for an optical CR count measurement.

The measurement is compiled according to the type of acquisition specified in the device configuration.

Parameters:

  • qubits – The qubits you want to measure

  • acq_channel – Only for special use cases. By default (if None): the acquisition channel specified in the device element is used. If set, this acquisition channel is used for this measurement.

  • acq_index – Index of the register where the measurement is stored. If None specified, it will default to a list of zeros of len(qubits)

  • acq_protocol – Acquisition protocol (currently "TriggerCount" and "Trace") are supported. If None is specified, the default protocol is chosen based on the device and backend configuration.

  • bin_mode – The binning mode that is to be used. If not None, it will overwrite the binning mode used for Measurements in the quantum-circuit to quantum-device compilation step.
