Quantum CZ Gate based on Single Gradient Metasurface
Qi Liu, Yu Tian, Zhaohua Tian +4
We propose a scheme to realize quantum controlled-Z (CZ) gates through single gradient metasurface. Using its unique parallel beam-splitting feature, i.e., a series of connected be…

A Parallel Beam Splitting Based on Gradient Metasurface: Preparation and Fusion of Quantum Entanglement
Qi Liu, Xuan Liu, Yu Tian +5
Gradient metasurface, formed by a set of subwavelength unit cells with different phase modulation, is widely used in polarized beam splitting (BS) in the classical and quantum opti…
