Tuning quantum magic of pure quantum chaotic states with a gravity dual
Antonio M. García-García, Xianlong Liu, Jie-ping Zheng
Quantum magic is a fundamental resource that quantifies to what extent quantum states can be efficiently simulated on a classical computer. We study it for states constructed from…
Inducing, and enhancing, many-body quantum chaos by continuous monitoring
Xianlong Liu, Jie-ping Zheng, Antonio M. García-García
It is intuitively expected, and supported by earlier studies, that many-body quantum chaos is suppressed, or even destroyed, by dissipative effects induced by continuous monitoring…
Thermofield Theory of Large Matrix Models
Antal Jevicki, Xianlong Liu, Junjie Zheng
We develop analytical and numerical methods for the matrix thermofield in the large limit. Through the double collective representation on the Schwinger-Keldysh contour, it pro…
Deep learning and random light structuring ensure robust free-space communications
Xiaofei Li, Yu Wang, Xin Liu +4
Having shown early promise, free-space optical communications (FSO) face formidable challenges in the age of information explosion. The ever-growing demand for greater channel comm…
A model of randomly-coupled Pauli spins
Masanori Hanada, Antal Jevicki, Xianlong Liu +2
We construct a model of Pauli spin operators with all-to-all 4-local interactions by replacing Majorana fermions in the SYK model with spin operators. Equivalently, we replace ferm…
