Super-Heisenberg Scaling Using Nonlinear Quantum Scrambling

Dong Xie, Chunling Xu

Super-Heisenberg scaling, which scales as $N^{- β}$ with $β > 1$ in terms of the number of particles $N$ or $T^{- β}$ in terms of the evolution time $T$ , is better than Heisenberg scal…

Gravimetry enhanced by nonreciprocal optomechanical coupling

Dong Xie, Chunling Xu

We explore how to measure the gravitational acceleration by using a dissipative optomechanical cavity. What is quite different from the conventional measurement methods is that we…
