Beating the break-even point with autonomous quantum error correction
Yi Li, Qingyuan Mei, Qing-Xuan Jie +13
Quantum error correction (QEC) is essential for practical quantum computing, as it protects fragile quantum information from errors by encoding it in high-dimensional Hilbert space…
Experimental realization and synchronization of a quantum van der Pol oscillator
Yi Li, Zihan Xie, Xiaodong Yang +8
Classical self-sustained oscillators, that generate periodic motion without periodic external forcing, are ubiquitous in science and technology. The realization of nonclassical sel…
Experimental observation of parity-symmetry-protected phenomena in the quantum Rabi model with a trapped ion
Xingyu Zhao, Qian Bin, Waner Hou +5
Symmetry is crucial for gaining insights into the fundamental properties of physical systems, bringing possibilities in studying exotic phenomena such as quantum phase transitions…
Programmable simulation of high-order exceptional point with a trapped ion
Yue Li, Yang Wu, Yuqi Zhou +9
The nontrivial degeneracies in non-Hermitian systems, exceptional points (EPs), have attracted extensive attention due to intriguing phenomena. Compared with commonly observed seco…
