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...

Small Unextendible Sets of MUBs
Abstract: In quantum information, Mutually Unbiased Bases (MUBs) correspond to sets of pairwise complementary observables. The maximal number of such bases in a system of dimension d is d+1, and cons...

Optical levitation and quantum spin-optomechanics of levitated nanodiamonds
Abstract: Optomechanical systems, such as LIGO (Laser Interferometer Gravitational-Wave Observatory), are extremely sensitive devices that have broad applications. Once cooled to the quantum regime, ...
