Dense Coding Capacity in Correlated Noisy Channels with Weak Measurement
Jin-Kai Li, Kai Xu, Guo-Feng Zhang
Capacity of dense coding via correlated noisy channel is greater than that in uncorrelated noisy channel. It is shown that weak measurement and reversal measurement can make furthe…
Quantum simulation of Hawking radiation and curved spacetime with a superconducting on-chip black hole
Yun-Hao Shi, Run-Qiu Yang, Zhongcheng Xiang +10
Hawking radiation is one of the quantum features of a black hole that can be understood as a quantum tunneling across the event horizon of the black hole, but it is quite difficult…
Observation of Emergent Gauge Invariance in a Superconducting Circuit
Zhan Wang, Zi-Yong Ge, Zhongcheng Xiang +8
Lattice gauge theories (LGTs) are one of the most fundamental subjects in many-body physics, and has recently attracted considerable research interests in quantum simulations. Here…
Determination of parameters of a potential model for tetraquark study by studying all S-wave mesons
Zheng Zhao, Kai Xu, Attaphon Kaewsnod +3
The masses of low-lying S-wave mesons are evaluated in a constituent quark model (CQM) where the Cornell-like potential and one-gluon exchange spin-spin interaction are employed. T…
Study of light tetraquark spectroscopy
Zheng Zhao, Kai Xu, Attaphon Kaewsnod +3
We calculate the masses of the tetraquark ground state and first radial excited state in a constituent quark model where the Cornell-like potential and one-gluon e…
Probing Operator Spreading via Floquet Engineering in a Superconducting Circuit
S. K. Zhao, Zi-Yong Ge, Zhongcheng Xiang +16
Operator spreading, often characterized by out-of-time-order correlators (OTOCs), is one of the central concepts in quantum many-body physics. However, measuring OTOCs is experimen…
