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…

Noise-Resilient Heisenberg-limited Quantum Sensing via Indefinite-Causal-Order Error Correction

Hang Xu, Xiaoyang Deng, Ze Zheng +2

Quantum resources can, in principle, enable Heisenberg-limited (HL) sensing, yet no-go theorems imply that HL scaling is generically unattainable in realistic noisy devices. While…

Optical diffraction neural networks assisted computational ghost imaging through dynamic scattering media

Yue-Gang Li, Ze Zheng, Jun-jie Wang +4

Ghost imaging leverages a single-pixel detector with no spatial resolution to acquire object echo intensity signals, which are correlated with illumination patterns to reconstruct…
