Higher-order noise statistics restore Heisenberg scaling under collective dephasing
Jiaxin Liu, Xing Heng, Zuoxian Wang +1
Noisy-metrology theory characterizes decoherence by its two-point correlation function, equivalently the single-atom coherence time or noise spectrum. We show this is insufficient…

Search for a parity-violating long-range spin-dependent interaction
Xing Heng, Zitong Xu, Xiaofei Huang +6
High-sensitivity quantum sensors are a promising tool for experimental searches for beyond-Standard-Model interactions. Here, we demonstrate an atomic comagnetometer operating unde…
