Researchers at Heilongjiang University have demonstrated a compact, single-layer metasurface capable of performing high-fidelity optical controlled-Y gates essential for universal quantum computation. By leveraging polarization-encoded photons and parallel beam splitting, the device achieves matrix fidelities exceeding 0.98 across multiple measurement bases, validating its potential as a monolithic platform for entangled-state manipulation. Operating at the standard 1550 nm wavelength with an estimated 26.5 nm bandwidth, this design offers a promising pathway for integrating quantum logic directly into existing photonic communication infrastructure.
