Polaron Transformed Canonically Consistent Quantum Master Equation
Juzar Thingna, Xiansong Xu, Daniel Manzano
A central challenge in the theory of open quantum systems is the development of theoretical frameworks capable of accurately describing large, strongly interacting quantum many-bod…
Continuous-time parametrization of neural quantum states for quantum dynamics
Dingzu Wang, Wenxuan Zhang, Xiansong Xu +1
Neural quantum states are a promising framework for simulating many-body quantum dynamics, as they can represent states with volume-law entanglement. As time evolves, the neural ne…
Emergence of steady quantum transport in a superconducting processor
Pengfei Zhang, Yu Gao, Xiansong Xu +29
Non-equilibrium quantum transport is crucial to technological advances ranging from nanoelectronics to thermal management. In essence, it deals with the coherent transfer of energy…
Paths towards time evolution with larger neural-network quantum states
Wenxuan Zhang, Bo Xing, Xiansong Xu +1
In recent years, the neural-network quantum states method has been investigated to study the ground state and the time evolution of many-body quantum systems. Here we expand on the…
Hydrodynamics and the eigenstate thermalization hypothesis
Luca Capizzi, Jiaozi Wang, Xiansong Xu +2
The eigenstate thermalization hypothesis (ETH) describes the properties of diagonal and off-diagonal matrix elements of local operators in the eigenenergy basis. In this work, we p…
Simulating quantum transport via collisional models on a digital quantum computer
Rebecca Erbanni, Xiansong Xu, Tommaso Demarie +1
Digital quantum computers have the potential to study the dynamics of complex quantum systems. Nonequilibrium open quantum systems are, however, less straightforward to be implemen…
A real neural network state for quantum chemistry
Yangjun Wu, Xiansong Xu, Dario Poletti +3
The restricted Boltzmann machine (RBM) has been successfully applied to solve the many-electron Schrdinger equation. In this work we propose a single-layer fully c…
Efficacy of noisy dynamical decoupling
Jiaan Qi, Xiansong Xu, Dario Poletti +1
Dynamical decoupling (DD) refers to a well-established family of methods for error mitigation, comprising pulse sequences aimed at averaging away slowly evolving noise in quantum s…
Ground state search by local and sequential updates of neural network quantum states
Wenxuan Zhang, Xiansong Xu, Zheyu Wu +2
Neural network quantum states are a promising tool to analyze complex quantum systems given their representative power. It can however be difficult to optimize efficiently and effe…
Interaction-impeded relaxation in the presence of finite temperature baths
Ryan Tan, Xiansong Xu, Dario Poletti
We study the interplay between interactions and finite-temperature dephasing baths. We consider a double well with strongly interacting bosons coupled, via the density, to a bosoni…
