paraqeet.measurement.mixed_state_transfer_fidelity.MixedStateTransferFidelity

class paraqeet.measurement.mixed_state_transfer_fidelity.MixedStateTransferFidelity(propagation, targetState)

Bases: Measurement

Mixed state transfer fidelity measurement model.

Fidelity measure that compares the overlap of the initial and final state of density matrices. Note: this implementation is still very inaccurate.

Parameters:

• propagation (Propagation) – Abstract base class for any implementation that can solve the equation of motion.

• targetState (Array) – Final state of the density matrices.

• times (Array) – One-dimensional vector of timestamps.

__init__(propagation, targetState)

Parameters:

• propagation (Propagation)

• targetState (Array)

Methods

__init__(propagation, targetState)
measure(times)	Measure overlap between initial and final state of density matrices.

measure(times)

Measure overlap between initial and final state of density matrices.

Returns:

Overlap between initial and final state of density matrices.

Return type:

Array

Raises:

IncompatibleLayersException – Raises an exception if required vector shape is not received.

Parameters:

times (Array)
