Entanglement-Enhanced Quantum Metrology in Colored Noise by Quantum Zeno Effect

Xinyue Long, Wan-Ting He, Na-Na Zhang +9

In open quantum systems, the precision of metrology inevitably suffers from the noise. {In Markovian open quantum dynamics, the precision can not be improved by using entangled pro…

Experimental quantum simulation of non-Hermitian dynamical topological states using stochastic Schrödinger equation

Zidong Lin, Lin Zhang, Xinyue Long +8

Noise is ubiquitous in real quantum systems, leading to non-Hermitian quantum dynamics, and may affect the fundamental states of matter. Here we report in experiment a quantum simu…

On Hermitian manifolds with vanishing curvature

Kyle Broder, Kai Tang

We show that Hermitian metrics with vanishing holomorphic curvature on compact complex manifolds with pseudoeffective canonical bundle are conformally balanced. Pluriclosed metrics…
