Practical quantum simulation of small-scale non-Hermitian dynamics
Hongfeng Liu, Xiaodong Yang, Kai Tang +5
Non-Hermitian quantum systems have recently attracted considerable attention due to their exotic properties. Though many experimental realizations of non-Hermitian systems have bee…
Control-enhanced quantum metrology under Markovian noise
Yue Zhai, Xiaodong Yang, Kai Tang +5
Quantum metrology is supposed to significantly improve the precision of parameter estimation by utilizing suitable quantum resources. However, the predicted precision can be severe…
Experimental realization of a topologically protected Hadamard gate via braiding Fibonacci anyons
Yu-ang Fan, Yingcheng Li, Yuting Hu +9
Topological quantum computation (TQC) is one of the most striking architectures that can realize fault-tolerant quantum computers. In TQC, the logical space and the quantum gates a…
Measuring Quantum Entanglement from Local Information by Machine Learning
Yulei Huang, Liangyu Che, Chao Wei +5
Entanglement is a key property in the development of quantum technologies and in the study of quantum many-body simulations. However, entanglement measurement typically requires qu…
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…
