Operations

Name	Summary
ContinuousPhaseEstimationIteration	Performs a single iteration of an iterative (classically-controlled) phase estimation algorithm using arbitrary real powers of a unitary oracle.
DiscretePhaseEstimationIteration	Performs a single iteration of an iterative (classically-controlled) phase estimation algorithm using integer powers of a unitary oracle.
EstimateFrequency	Given a preparation and measurement, estimates the frequency with which that measurement succeeds (returns Zero) by performing a given number of trials.
EstimateFrequencyA	Given a preparation that is adjointable and measurement, estimates the frequency with which that measurement succeeds (returns Zero) by performing a given number of trials.
EstimateImagOverlapBetweenStates	Given two operations which each prepare copies of a state, estimates the imaginary part of the overlap between the states prepared by each operation.
EstimateOverlapBetweenStates	Given two operations which each prepare copies of a state, estimates the squared overlap between the states prepared by each operation.
EstimateRealOverlapBetweenStates	Given two operations which each prepare copies of a state, estimates the real part of the overlap between the states prepared by each operation.
MeasureAllZ	> [!WARNING]
MeasureIdentity	Measures the identity operator on a register of qubits.
QuantumPhaseEstimation	Performs the quantum phase estimation algorithm for a given oracle U and targetState, reading the phase into a big-endian quantum register.
RobustPhaseEstimation	Performs the robust non-iterative quantum phase estimation algorithm for a given oracle U and eigenstate, and provides a single real-valued estimate of the phase with variance scaling at the Heisenberg limit.
SingleQubitProcessTomographyMeasurement	Performs a single-qubit process tomography measurement in the Pauli basis, given a particular channel of interest.
