Massively parallel quantum computer simulator, eleven years later
Hans De Raedt, Fengping Jin, Dennis Willsch +5
A revised version of the massively parallel simulator of a universal quantum computer, described in this journal eleven years ago, is used to benchmark various gate-based quantum a…
Quantum Decoherence and Thermalization at Finite Temperature within the Canonical Thermal State Ensemble
M. A. Novotny, F. Jin, S. Yuan +3
We study measures of decoherence and thermalization of a quantum system in the presence of a quantum environment (bath) . The entirety is prepared in a canonical t…
Quantum Decoherence Scaling with Bath Size: Importance of Dynamics, Connectivity, and Randomness
Fengping Jin, Kristel Michielsen, Mark Novotny +3
The decoherence of a quantum system coupled to a quantum environment is considered. For states chosen uniformly at random from the unit hypersphere in the Hilbert space of…
Approach to equilbrium in nano-scale systems at finite temperatur
Fengping Jin, Hans De Raedt, Shengjun Yuan +3
We study the time evolution of the reduced density matrix of a system of spin-1/2 particles interacting with an environment of spin-1/2 particles. The initial state of the composit…
Decoherence and Thermalization of Quantum Spin Systems
Shengjun Yuan
In this review, we discuss the decoherence and thermalization of a quantum spin system interacting with a spin bath environment, by numerically solving the time-dependent Schröding…
Corpuscular model of two-beam interference and double-slit experiments with single photons
Fengping Jin, Shengjun Yuan, Hans De Raedt +2
We introduce an event-based corpuscular simulation model that reproduces the wave mechanical results of single-photon double slit and two-beam interference experiments and (of a on…
