Digital Quantum Simulation of the Lindblad Master Equation and Its Nonlinear Extensions via Quantum Trajectory Averaging
Yu-Guo Liu, Heng Fan, Shu Chen
Since precisely controlling dissipation in realistic environments is challenging, digital simulation of the Lindblad master equation (LME) is of great significance for understandin…
Maximal Entanglement and Frozen Information: A Unified Framework for Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
Dynamical quantum phase transitions (DQPTs) are temporal singularities marked by zeros of the Loschmidt echo, yet their underlying quantum-information structure remains elusive. He…
Tailoring Dynamical Quantum Phase Transitions via Double-Mode Squeezing Manipulation
Kaiyuan Cao, Haodong Wang, Xiang-Ping Jiang +2
We propose a protocol to tailor dynamical quantum phase transitions (DQPTs) by double-mode squeezing onto the initial state in the XY chain. The effect of squeezing depends critica…
Relation between equilibrium quantum phase transitions and dynamical quantum phase transitions in two-band systems
Yumeng Zeng, Shu Chen
The dynamical quantum phase transition (DQPT) is an important concept in nonequilibrium critical phenomena; however, its relation to the equilibrium quantum phase transition (EQPT)…
