Efficient Waveform Capture without Absorption with Synthesis of Complex Frequencies
Zhaohua Tian, Yu Tian, Yadi Niu +5
A optical waveform can be synthesized by complex-frequency waves as well as by real-frequency harmonic waves. While single complex-frequency wave with exponentially rising waveform…
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…
Cascade enhancement and efficient collection of single photon emission under topological protection
Yali Jia, Zhaohua Tian, Qi Liu +3
High emission rate, high collection efficiency, and immunity to the defects are the requirements of implementing on-chip single photon sources. Here, we theoretically demonstrate t…
Topological-Vacuum-Induced Strong Photon-Exciton Coupling
Yali Jia, Zihan Mo, Qi Liu +4
The electromagnetic vacuum construction based on micro-nano photonic structures is able to engineer the photon-exciton interaction at the single quantum level. Here, through engine…
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…
