Polarization-Encoded Quantum Controlled-NOT Gate Based on a Single-layer Metasurface
We demonstrate a polarization-encoded quantum CNOT gate realized with a single-layer Pancharatnam–Berry phase-based dielectric metasurface. The truth table fidelity reaches 94.7% and state fidelities of the generated maximally entangled states exceed 80%.
