quri_parts.core.state.state_helper.apply_circuit(circuit: UnboundParametricQuantumCircuitProtocol, state: CircuitQuantumState) → ParametricCircuitQuantumState

quri_parts.core.state.state_helper.apply_circuit(circuit: UnboundParametricQuantumCircuitProtocol, state: QuantumStateVector) → ParametricQuantumStateVector

quri_parts.core.state.state_helper.apply_circuit(circuit: UnboundParametricQuantumCircuitProtocol, state: ParametricCircuitQuantumState) → ParametricCircuitQuantumState

quri_parts.core.state.state_helper.apply_circuit(circuit: UnboundParametricQuantumCircuitProtocol, state: ParametricQuantumStateVector) → ParametricQuantumStateVector

Returns a new state with the circuit applied.

The original state is not changed.

quri_parts.core.state.state_helper.quantum_state(n_qubits: int, vector: npt.NDArray[np.cfloat] | npt.ArrayLike | None = None, bits: int = 0, circuit: NonParametricQuantumCircuit | UnboundParametricQuantumCircuitProtocol | None = None) → QuantumState

Returns a quantum state generated by a given vector, bits, and a circuit.

Raises ValueError if both a vector and bits input at the same time.
