On-chip generation of multi-qubit graph states with high-dimensional encoded single photons
Lan-Tian Feng, Bo-Hao Zhang, Di Liu +5
Photonic multi-qubit entanglement is key to optical quantum information processing, particularly universal quantum computing. Yet multi-photon sources suffer from low emission effi…
Beating three-parameter precision trade-offs with entangling collective measurements
Simon K. Yung, Wen-Zhe Yan, Lan-Tian Feng +10
Quantum-mechanical incompatibility, which precludes the simultaneous precise measurement of non-commuting observables, imposes fundamental limits on the rate at which classical inf…
A single programmable photonic circuit for universal quantum measurements
Wen-Zhe Yan, Lan-Tian Feng, Zhibo Hou +7
Programmable photonic quantum processors face a critical challenge: despite significant advances in quantum state preparation and manipulation, measurements remain limited to proje…
Efficient cryogenic nonlinear conversion processes in periodically-poled thin-film lithium niobate waveguides
Yujie Cheng, Xiaoting Li, Lantian Feng +7
Periodically poled thin-film lithium niobate (TFLN) waveguides, which enable efficient quadratic nonlinear processes, serve as crucial foundation for classical and quantum signal p…
Chip-to-chip quantum photonic controlled-NOT gate teleportation
Lan-Tian Feng, Ming Zhang, Di Liu +7
Quantum networks provide a novel framework for quantum information processing, significantly enhancing system capacity through the interconnection of modular quantum nodes. Beyond…
Global calibration of large-scale photonic integrated circuits
Jin-Hao Zheng, Qin-Qin Wang, Lan-Tian Feng +5
The growing maturity of photonic integrated circuit (PIC) fabrication technology enables the high integration of an increasing number of optical components onto a single chip. With…
