Cascadable Quantum Controlled-Z Gates on a Single Metasurface
We theoretically demonstrate several cascadable quantum controlled-Z gates on a single metasurface by utilizing its parallel beam-splitting capability, which is valid for both polarization and path-encoding qubits. The path-encoding case can filter out bit-flip errors.
