Figure | Working principle of the metasurface quantum CZ gates. (a) Schematic diagram of polarization-encoded quantum CZ gate through single gradient metasurface. (b) Mechanism of polarization-encoding quantum CZ gate with the help of parallel beam-splitting on the metasurface. (c) Two quantum CZ gates are cascaded on a single metasurface by sharing the control qubit.
