Spectral truncations of SU(2) and the spectral localizer
Matt Verhoeven
We study operator systems arising from Peter-Weyl and Dirac spectral truncations of in the sense of Connes-Van Suijlekom. We determine operator system invariants f…
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…
Accelerating ground state search of spatial photonic Ising machines with genetic-simulated annealing hybrid algorithm
Ze Zheng, Ruhui Ni, Jingyi Zhao +6
Spatial photonic Ising machines (SPIMs) based on spatial light modulators (SLMs) have emerged as highly effective solvers for many tasks, including combinatorial optimization probl…
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…
