CZSWAP and CXSWAP gate #6424

Open AlMrvn opened 5 months ago

AlMrvn commented 5 months ago

Is your feature request related to a use case or problem? Please describe. stim allow the use of gates like CZSWAP and CXSWAP but cirq doesn't have these gates.

stim define a stimcirq gate currently with all the parameters: stimcirq.CZSwapGate()

Describe the solution you'd like I would like for cirq to have a CZSWAP gate and a CXSWAP gate for easy moving back and forth between stim and cirq.

[optional] Describe alternatives/workarounds you've considered Using the FSIM gate is a possibility. However since it's a parametrized gate, it's not always practical to use.

@NoureldinYosri I've submitted a PR that implements the CXSWAP and CZSWAP gates for the Unitary Hack challenge.
