Given a circuit and a list of bitstrings, computes the amplitudes of the given bitstrings in the state obtained by applying the circuit to the all zeros state. Implementors of this interface should implement the compute_amplitudes_sweep method.
Methods
compute_amplitudes
compute_amplitudes(
program: "cirq.Circuit",
bitstrings: Sequence[int],
param_resolver: "study.ParamResolverOrSimilarType" = None,
qubit_order: ops.QubitOrderOrList = ops.QubitOrder.DEFAULT
) > Sequence[complex]
Computes the desired amplitudes.
The initial state is assumed to be the all zeros state.
Args  

program

The circuit to simulate. 
bitstrings

The bitstrings whose amplitudes are desired, input
as an integer array where each integer is formed from measured
qubit values according to qubit_order from most to least
significant qubit, i.e. in bigendian ordering.

param_resolver

Parameters to run with the program. 
qubit_order

Determines the canonical ordering of the qubits. This is often used in specifying the initial state, i.e. the ordering of the computational basis states. 
Returns  

List of amplitudes.

Returns  

List of lists of amplitudes. The outer dimension indexes the circuit parameters and the inner dimension indexes the bitstrings.
