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…
Tailoring Synthetic Gauge Fields in Ultracold Atoms via Spatially Engineered Vector Beams
Huan Wang, Shangguo Zhu, Yun Long +2
Ultracold atoms, typically manipulated by scalar beams with uniform polarization, have propelled advances in quantum simulation, computation, and metrology. Yet, vector beams (VBs)…
Fitting magnetic field gradient with Heisenberg-scaling accuracy
Yong-Liang Zhang, Huan Wang, Li Jing +2
We propose a quantum fitting scheme to estimate the magnetic field gradient with -atom spins preparing in W state, which attains the Heisenberg-scaling accuracy. Our scheme comb…
