SwapGate¶
-
class
SwapGate(label=None)[source]¶ Bases:
qiskit.circuit.gate.GateThe SWAP gate.
This is a symmetric and Clifford gate.
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.
Methods Defined Here
Return a (multi-)controlled-SWAP gate.
Return inverse Swap gate (itself).
