evolution_instruction

evolution_instruction(pauli_list, evo_time, num_time_slices, controlled=False, power=1, use_basis_gates=True, shallow_slicing=False, barrier=False)[source]

Construct the evolution circuit according to the supplied specification.

Parameters

  • pauli_list (list([[complex, Pauli]])) – The list of pauli terms corresponding to a single time slice to be evolved

  • evo_time (Union(complex, float, Parameter, ParameterExpression)) – The evolution time

  • num_time_slices (int) – The number of time slices for the expansion

  • controlled (bool, optional) – Controlled circuit or not

  • power (int, optional) – The power to which the unitary operator is to be raised

  • use_basis_gates (bool, optional) – boolean flag for indicating only using basis gates when building circuit.

  • shallow_slicing (bool, optional) – boolean flag for indicating using shallow qc.data reference repetition for slicing

  • barrier (bool, optional) – whether or not add barrier for every slice

Returns

The Instruction corresponding to specified evolution.

Return type

Instruction

Raises

  • AquaError – power must be an integer and greater or equal to 1

  • ValueError – Unrecognized pauli
