Optical bistability in a low-photon-density regime

2018 · Physical Review A

We give a microscopic description of the optical bistability, where the transmission coefficient has two different values as a function of input light intensity, and the system exhibits a discontinuous jump with a hysteresis loop. …

Benchmarking Supercomputers with the Jülich Universal Quantum Computer Simulator

2019 · arXiv (Cornell University)

We use a massively parallel simulator of a universal quantum computer to benchmark some of the most powerful supercomputers in the world. We find nearly ideal scaling behavior on the Sunway TaihuLight, the K computer, …

Discrete-Event Simulation of Quantum Walks

2020 · Frontiers in Physics

We use discrete-event simulation on a digital computer to study two different models of experimentally realizable quantum walks. The simulation models comply with Einstein locality, are as ``realistic'' as the one of the simple random …
