qiskit.ml.circuit.library.RawFeatureVector.tensor

RawFeatureVector.tensor(other, inplace=False)

Tensor self with other.

Remember that in the little-endian convention the leftmost operation will be at the bottom of the circuit. See also [the docs](qiskit.org/documentation/tutorials/circuits/3_summary_of_quantum_operations.html) for more information.

Parameters

• other (QuantumCircuit) – The other circuit to tensor this circuit with.

• inplace (bool) – If True, modify the object. Otherwise return composed circuit.

Examples

from qiskit import QuantumCircuit
top = QuantumCircuit(1)
top.x(0);
bottom = QuantumCircuit(2)
bottom.cry(0.2, 0, 1);
tensored = bottom.tensor(top)
print(tensored.draw())

     └─────────┘

Returns

The tensored circuit (returns None if inplace==True).

Return type

QuantumCircuit
