Probing the dynamical phase transition with a superconducting quantum simulator
Kai Xu, Zheng-Hang Sun, Wuxin Liu +9
Non-equilibrium quantum many-body systems, which are difficult to study via classical computation, have attracted wide interest. Quantum simulation can provide insights into these…
Realizing the Hayden-Preskill Protocol with Coupled Dicke Models
Yanting Cheng, Chang liu, Jinkang Guo +3
Hayden and Preskill proposed a thought experiment that Bob can recover the information Alice throws into a black hole if he has a quantum computer entangled with the black hole, an…
Evaporation dynamics of the Sachdev-Ye-Kitaev model
Pengfei Zhang
In this paper, we study the evaporation dynamics of the Sachdev-Ye-Kitaev (SYK) model, with an initial temperature , by coupling it to a thermal bath with lower temperature $T…
Many-Body Echo
Yang-Yang Chen, Pengfei Zhang, Wei Zheng +2
In this letter we propose a protocol to reverse a quantum many-body dynamical process. We name it "many-body echo" because the underlying physics is closely related to the spin ech…
Information Scrambling in Quantum Neural Networks
Huitao Shen, Pengfei Zhang, Yi-Zhuang You +1
The quantum neural network is one of the promising applications for near-term noisy intermediate-scale quantum computers. A quantum neural network distills the information from the…
Entanglement Entropy of Two Coupled SYK Models and Eternal Traversable Wormhole
Yiming Chen, Pengfei Zhang
In this paper, we study the entanglement entropy between two SYK systems with bilinear coupling. We use the replica trick to calculate the entanglement entropy in the ground state.…
