cirq.SimulatorStep

class cirq.SimulatorStep(state, measurements, qubit_map, dtype)

__init__(state, measurements, qubit_map, dtype)

Results of a step of the simulator.

qubit_map

A map from the Qubits in the Circuit to the the index

of this qubit for a canonical ordering. This canonical ordering

is used to define the state (see the state() method).

measurements

A dictionary from measurement gate key to measurement

results, ordered by the qubits that the measurement operates on.

Methods

bloch_vector(index)	Returns the bloch vector of a qubit.
density_matrix(indices)	Returns the density matrix of the wavefunction.
dirac_notation(decimals)	Returns the wavefunction as a string in Dirac notation.
sample(qubits, repetitions)	Samples from the wave function at this point in the computation.
sample_measurement_ops(measurement_ops, …)	Samples from the wave function at this point in the computation.
set_state(state, numpy.ndarray])	Updates the state of the simulator to the given new state.
state()	Return the state (wave function) at this point in the computation.
