Simultaneous Heisenberg-Limited Multiparameter Metrology via Indefinite Evolution
Hang Xu, Tailong Xiao, Ze Zheng +4
Quantum metrology achieves Heisenberg-limited precision in single-parameter estimation, but its multiparameter extension is fundamentally constrained by both parameter-encoding and…
Preserving Heisenberg-Limited Metrological Information during Storage via Correlated-Noise Correction
Hang Xu, Xue-Ke Song, Jingzheng Huang +2
Quantum error correction has become an indispensable tool for restoring Heisenberg-limited precision in noisy quantum metrology. Existing protocols, however, almost exclusively foc…
Converting Quantum Sensing Noise into Erasures
Xingyu Liu, Zhaotong Cui, Binke Xia +4
The paper introduces a passive scheme that converts certain quantum sensing noise into erasures, enabling robust sensing without detailed noise knowledge, and demonstrates the meth…
Incorporating rank-free coupling and external field via an incoherent modulated spatial photonic Ising machine
Ze Zheng, Yuegang Li, Hang Xu +3
Spatial photonic Ising machines offer a novel optical platform for optimization and spin-model simulation, but existing diffraction-based schemes rely on auxiliary spins or multipl…
Noise-resilient nanophotonic gyroscope with sub-prad phase resolution
Yu Tao, Xinhang Li, Jingzheng Huang +5
Optical gyroscopes based on the Sagnac effect are the cornerstone of precision orientation and navigation. However, their bulky form factors prevent deployment in emerging mobile a…
Fault-Tolerant Information Processing with Quantum Weak Measurement
Qi Song, Hongjing Li, Chengxi Yu +4
Noise is an important factor that influences the reliability of information acquisition, transmission, processing, and storage. In order to suppress the inevitable noise effects, a…
