VBE Ripple-Carry Adder.

Module Contents¶

create_circuit(num_qubits: int, kind: str = 'full') → QuantumCircuit[source]¶

Create a vbe ripple-carry adder circuit.

Parameters:

num_qubits – Number of qubits of the returned quantum circuit
kind – The kind of adder, can be "full" for a full adder, "half" for a half adder, or "fixed" for a fixed-sized adder. A full adder includes both carry-in and carry-out, a half only carry-out, and a fixed-sized adder neither carry-in nor carry-out. Additionally, num_state_qubits - 1 ancillary qubits are added. For example if num_qubits=13 and kind=”full”, there is one qubit for carry-in, one qubit for carry-out, num_state_qubits=4 for each of the 2 registers, and num_state_qubits-1=3 ancillary qubits.

Returns:

QuantumCircuit – The constructed vbe ripple-carry adder circuit.
