State -designs from Hamiltonian evolution
Shengxian Hou, Zong-Yue Hou, Zhi-Cheng Yang
We study the generation of state -designs from time evolution under a fixed Hamiltonian. Specifically, we consider the ensemble $\mathcal{E}=\left\{e^{-iHt}|ψ_0\rangle | \ t\sim…

Quantum metrology enhanced by coherence-induced-driving in a cavity QED setup
Weijun Cheng, S. C. Hou, Zhihai Wang +1
We propose a quantum metrology scheme in a cavity QED setup to achieve the Heisenberg limit. In our scheme, a series of identical two-level atoms randomly pass through and interact…
