Conversion of photon temporal shape using single gradient metasurface
Zhaohua Tian, Qi Liu, Yu Tian +1
By applying phase modulation across different frequencies, metasurfaces possess the ability to manipulate the temporal dimension of photons at the femtosecond scale. However, there…
Near-symmetric multiport beam splitting for high-NOON state preparation on nonlocal metasurface
Yu Tian, Qi Liu, Zhaohua Tian +2
Polarization beam splitting (BS) has been implemented on gradient metasurface with local response for entanglement manipulation and state reconstruction. To realize more degrees of…
Wavepacket interference of two photons through a beam splitter: from temporal entanglement to wavepacket shaping
Zhaohua Tian, Qi Liu, Yu Tian +1
Quantum interferences based on beam splitting are widely used for entanglement. However, the quantitative measurement of the entanglement in terms of temporal modes and wavepacket…
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…
