Complexity for an open quantum system [PDF]
Physical Review D, 2021 We study the complexity for an open quantum system. Our system is a harmonic oscillator coupled to a one-dimensional massless scalar field, which acts as the bath.

Scarring in open quantum systems [PDF]
Physical Review E, 2007 We study scarring phenomena in open quantum systems. We show numerical evidence that individual resonance eigenstates of an open quantum system present localization around unstable short periodic orbits in a similar way as their closed counterparts.

Digital Quantum Simulation of Open Quantum Systems Using Quantum Imaginary–Time Evolution [PDF]
PRX Quantum, 2022 Quantum simulation on emerging quantum hardware is a topic of intense interest. While many studies focus on computing ground-state properties or simulating unitary dynamics of closed systems, open quantum systems are an interesting target of study owing ...

Shortcut to Equilibration of an Open Quantum System. [PDF]
Physical Review Letters, 2018 We present a procedure to accelerate the relaxation of an open quantum system towards its equilibrium state. The control protocol, termed the shortcut to equilibration, is obtained by reverse-engineering the nonadiabatic master equation.

Large-scale stochastic simulation of open quantum systems [PDF]
Nature CommunicationsUnderstanding interactions between quantum systems and their environments is crucial for developing stable quantum technologies and accurate physical models. Yet, simulating open quantum systems with non-unitary dynamics remains computationally demanding.

Assisted quantum simulation of open quantum systems [PDF]
iScience, 2023 Universal quantum algorithms (UQA) implemented on fault-tolerant quantum computers are expected to achieve an exponential speedup over classical counterparts. However, the deep quantum circuits makes the UQA implausible in the current era. With only the noisy intermediate-scale quantum (NISQ) devices in hand, we introduce the quantum-assisted quantum ...

Open Quantum System Dynamics from Infinite Tensor Network Contraction. [PDF]
Physical Review Letters, 2023 Approaching the long-time dynamics of non-Markovian open quantum systems presents a challenging task if the bath is strongly coupled. Recent proposals address this problem through a representation of the so-called process tensor in terms of a tensor ...

Simulating Open Quantum System Dynamics on NISQ Computers with Generalized Quantum Master Equations. [PDF]
Journal of Chemical Theory and Computation, 2022 We present a quantum algorithm based on the generalized quantum master equation (GQME) approach to simulate open quantum system dynamics on noisy intermediate-scale quantum (NISQ) computers.

Open quantum system dynamics and the mean force Gibbs state [PDF]
AVS Quantum Science, 2021 The dynamical convergence of a system to the thermal distribution, or Gibbs state, is a standard assumption across all of the physical sciences. The Gibbs state is determined just by temperature and energies of the system.

Experimental Simulation of Open Quantum System Dynamics via Trotterization. [PDF]
Physical Review Letters, 2021 Digital quantum simulators provide a diversified tool for solving the evolution of quantum systems with complicated Hamiltonians and hold great potential for a wide range of applications. Although much attention is paid to the unitary evolution of closed
