SWAP gate.

Classes

GateSWAP()

Two qubit SWAP gate.

class mimiqcircuits.operations.gates.standard.swap.GateSWAP

Bases: Gate

Two qubit SWAP gate.

See Also GateISWAP()

Matrix representation:

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

Examples

>>> from mimiqcircuits import *
>>> GateSWAP()
SWAP
>>> GateSWAP().matrix()
[1.0, 0, 0, 0]
[0, 0, 1.0, 0]
[0, 1.0, 0, 0]
[0, 0, 0, 1.0]

inverse()

Raise an error, as non-unitary operators cannot be inverted.

This method is not implemented for non-unitary operators and will raise a NotImplementedError if called.

Raises:

NotImplementedError – If the method is called.
