SwapGate

class SwapGate(label=None)[ソース]

ベースクラス: Gate

The SWAP gate.

This is a symmetric and Clifford gate.

Can be applied to a QuantumCircuit with the swap() method.

Circuit symbol:

q_0: ─X─
      │
q_1: ─X─

Matrix Representation:

\[\begin{split}SWAP = \begin{pmatrix} 1 & 0 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 0 & 1 \end{pmatrix}\end{split}\]

The gate is equivalent to a state swap and is a classical logic gate.

\[|a, b\rangle \rightarrow |b, a\rangle\]

Create new SWAP gate.
