qiskit.aqua.components.initial_states.Zero¶
-
class
Zero(num_qubits)[source]¶ 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
- Parameters
num_qubits (
int) – Number of qubits, has a minimum value of 1.
-
__init__(num_qubits)[source]¶ - Parameters
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.

-
construct_circuit(mode='circuit', register=None)[source]¶ Construct the statevector of desired initial state.
- Parameters
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.
- Returns
statevector.
- Return type
QuantumCircuit or numpy.ndarray
- Raises
AquaError – when mode is not ‘vector’ or ‘circuit’.
