Quantum computing of quantum chaos and imperfection effects
Pil Hun Song, Dima L. Shepelyansky
We study numerically the imperfection effects in the quantum computing of the kicked rotator model in the regime of quantum chaos. It is shown that there are two types of physical…

Scaling near Quantum Chaos Border in Interacting Fermi Systems
Pil Hun Song
The emergence of quantum chaos for interacting Fermi systems is investigated by numerical calculation of the level spacing distribution as function of interaction strength $…
