qiskit.chemistry.components.initial_states.VSCF

class VSCF(basis)

Initial state for vibrational modes.

Creates an occupation number vector as defined in Ollitrault Pauline J., Chemical science 11 (2020): 6842-6855. e.g. for 2 modes with 4 modals per mode it creates: |1000 1000>

매개변수

basis (List[int]) – Is a list defining the number of modals per mode. E.g. for a 3 modes system with 4 modals per mode basis = [4,4,4]

__init__(basis)

Methods

__init__(basis)	type basis List[int]
construct_circuit([mode, register])	Construct the circuit of desired initial state.

Attributes

bitstr

Getter of the bit string represented the statevector.

property bitstr

Getter of the bit string represented the statevector.

반환 형식

ndarray

반환값

numpy.ndarray containing the bitstring representation

construct_circuit(mode='circuit', register=None)

Construct the circuit of desired initial state.

매개변수

• mode (str) – vector or circuit. The vector mode produces the vector. While the circuit constructs the quantum circuit corresponding that vector.

• register (QuantumRegister) – register for circuit construction.

반환값

statevector.

반환 형식

QuantumCircuit or numpy.ndarray

예외

ValueError – when mode is not ‘vector’ or ‘circuit’.
