qiskit.aqua.components.initial_states.Zero

class Zero(num_qubits)

The zero (null/vacuum) state.

This is suitable for those situations in which the all-zeros state is the desired state. This is the case for a vacuum state in physics or chemistry

Parâmetros

num_qubits (int) – Number of qubits, has a minimum value of 1.

__init__(num_qubits)

Parâmetros

num_qubits (int) – Number of qubits, has a minimum value of 1.

Methods

__init__(num_qubits)	type num_qubits int
construct_circuit([mode, register])	Construct the statevector of desired initial state.

Attributes

bitstr

property bitstr

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

Construct the statevector of desired initial state.

Parâmetros

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

• register – qubits for circuit construction.

Retorna

statevector.

Tipo de retorno

QuantumCircuit or numpy.ndarray

Levanta

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