High Success Probability, Fidelity, and Purity Nonlinear Optical Two-Qubit Gates on Chip
Minghao Shang, Hua-Ying Liu, Ying Wei +5
Optical two-qubit gate with high success probability, fault-tolerant fidelity, and high-purity outputs is a fundamental yet unsolved challenge, essential for large-scale optical qu…
Experimental Tabletop Petz recovery of a photonic qubit
Hui Li, Jinyan Chen, Yue Pan +4
The quantum information lost in open evolutions cannot be fully recovered, but partial recovery is possible. The Petz recovery map guarantees almost optimal recovery, notably if th…
Experimental Joint Estimation of Phase and Phase Diffusion via Deterministic Bell Measurements
Ben Wang, Minghao Mi, Huangqiuchen Wang +2
Accurate phase estimation plays a pivotal role in quantum metrology, yet its precision is significantly affected by noise, particularly phase-diffusive noise caused by phase drift.…
Photonic implementation of quantum hidden subgroup database compression
Qianyi Wang, Feiyang Liu, Teng Hu +6
We experimentally demonstrate quantum data compression exploiting hidden subgroup symmetries using a photonic quantum processor. Classical databases containing generalized periodic…
Superresolution of unequal-brightness thermal sources for stellar interferometry
Chenyu Hu, Ben Wang, Jiandong Zhang +4
Resolving high-contrast targets is a fundamental yet highly challenging task in astronomy. Using quantum estimation theory, we demonstrate that the ultimate limit for estimating th…
