class loom.cliffordsim.operations.measurement_operation.Measurement(target_qubit, label=<factory>, reg_name=None, bit_order=None, bit_id=None, basis='Z', bias=0.5)

Bases: MeasurementOperation

Creates a measurement operation for a single qubit. By default, the output of the measurement is saved to the DataStore. If the user wants to write the output onto the classical register, the classical register needs to be specified with reg_name and (bit_order or bit_id).

Parameters:

• label (str) – The ID of the Measurement Operation. Automatically generated by Default.

• reg_name (Optional[str]) – The name of the classical register to write the measurement output to.

• bit_order (Optional[int]) – The ordering of the bit within the classical register to write the measurement output to.

• bit_id (Optional[str]) – The bit ID of the bit within the classical register to write the measurement output to.

• basis (str) – The basis of the measurement. Default is Z.

• bias (float) – The bias of the measurement. Default is 0.5.

basis: str = 'Z'

bias: float = 0.5

bit_id: Optional[str] = None

bit_order: Optional[int] = None

label: str

name: str = 'Measurement'

reg_name: Optional[str] = None

class loom.cliffordsim.operations.measurement_operation.MeasurementOperation(target_qubit)

Bases: Operation

Operations of this type perform measurements on qubits within the Engine during runtime.

operation_type: str = 'Measurement'

target_qubit: int

with_ccontrol(reg_name, bit_order=None, bit_id=None)

This method returns a ControlledOperation wrapped version of the Operation class. The wrapped Operation class is classically controlled by the bit from the classical register specified by reg_name in bit_order or by bit_id.

NOTE: ControlledOperation(s) can only be conditioned on one classical bit.

class loom.cliffordsim.operations.measurement_operation.Reset(target_qubit, label=<factory>, state='0')

Bases: MeasurementOperation

Resets a qubit to a specific cardinal state. By default, the qubit is reset to the |0> state.

Parameters:

state (str) – The state to which the qubit is reset. The state can be one of the following: 0, 1, +, -, +i, -i. Default is 0.

label: str

name: str = 'Reset'

state: str = '0'
