Unifying the Anderson Transitions in Hermitian and Non-Hermitian Systems
Abstract: Altland-Zirnbauer (1997) gave ten-fold symmetry classification of disordered electron system. The localization property and critical behavior of electron is universal in a given spatial dim...

Quantum Journal Club: Hong-Ou-Mandel Interference between Two Deterministic Collective Excitations in an Atomic Ensemble
Abstract: We demonstrate deterministic generation of two distinct collective excitations in one atomic ensemble, and we realize the Hong-Ou-Mandel interference between them. Using Rydberg blockade we...

Long-Lived Solid-State Room-Temperature Quantum Memory
Abstract: One of the major obstacles in quantum information technology is to prevent a quantum bit (qubit) from dephasing, while still being able to reliably manipulate and readout the qubit. In the ...
