The Lieb-Schultz-Mattis (LSM) theorem is an important result in condensed matter physics. The LSM theorem states that a spin chain with half-integer spin and translation and rotation symmetry can not ...

Exceptional points (EPs) are singularities in the spectra of non-Hermitian operators where eigenvalues and eigenvectors coalesce. Open quantum systems have recently been explored as EP testbeds due to ...

Quantum systems in nature are inherently open—they inevitably interact with an environment, except in extreme cases of perfectly isolated particles. As a prototypical example, we consider ...

The University of Osaka, Fujitsu Limited, Systems Engineering Consultants Co., LTD. (SEC), and TIS Inc. (TIS) today announced the launch of an open-source operating system (OS) for quantum computers ...
