Numerically-Exact Quantum-Simulation Approach for Two-Dimensional Spectroscopy of Open Quantum Systems
Yi-Xuan Yao, Hao-Yue Zhang, Cheng-Ge Liu +3
Two-dimensional spectroscopy (2DS) is a powerful ultrafast technique for probing electronic and vibrational dynamics in complex microscopic systems. Extracting detailed information…
Fiber-integrated Quantum Frequency Conversion for Long-distance Quantum Networking
Zhichuan Liao, Ao Shen, Lai Zhou +2
Signal photons emitted by quantum nodes typically fall outside the low-loss telecom window of optical fibers, leading to severe transmission losses. Quantum frequency conversion (Q…
Coherent control of optomechanical entanglement and steering via dual parametric amplification
Jinhao Jia, Yingru Li, Ran Liang +1
We propose a coherent control scheme for engineering quantum correlations in a cavity optomechanical (COM) system consisting of a driven optical cavity with an embedded nonlinear m…
Investigating Lipkin-Meshkov-Glick Model and Criticality-Enhanced Metrology in a Coherent Ising Machine
Shuang-Quan Ma, Jing-Yi-Ran Jin, Chen-Rui Fan +2
Quantum criticality has received extensive attention due to its ability to significantly enhance quantum sensing. But its realization and control in many-body quantum systems remai…
Quantum Phase Transitions in Coherent Ising Machines: XY Model for Demonstration
Shuang-Quan Ma, Jing-Yi-Ran Jin, Qing Ai
In this work, we study the detection of quantum phase transitions (QPTs) in coherent Ising machines (CIMs) through a spectral mapping between the one-dimensional XY spin model and…
Quantum batteries in coherent Ising machine
Jin-Tian Zhang, Shuang-Quan Ma, Jing-Yi-Ran Jin +2
With intensive studies of quantum thermodynamics, quantum batteries (QBs) have been proposed to store and transfer energy via quantum effects. Despite many theoretical models, deco…
