Quantum Journal Club: Coherent and dynamic beam splitting based on light storage in cold atoms
Abstract: We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically induced t...

Spin-Dipole Coupling as Information Storage and Processing in Multiferroics
Abstract: Multiferroics, where permanent electric dipoles strongly couple to magnetic spins [1-3], are emerging as a novel tool for information technology. While conventional memory materials employ ...

Quantum Journal Club: Demonstration of a Coherent Electronic Spin Cluster in Diamond
Abstract: An obstacle for spin-based quantum sensors is magnetic noise due to proximal spins. However, a cluster of such spins can become an asset, if it can be controlled. Here, we polarize and read...

Quantum Journal Club: Spin–orbit-coupled Bose–Einstein condensates
Abstract: Spin–orbit (SO) coupling—the interaction between a quantum particle’s spin and its momentum—is ubiquitous in physical systems. In condensed matter systems, SO coupling is crucial for th...

PSD rank and its applications in computer science and quantum physics
Abstract: Positive semidefinite (PSD) rank is a concept that was proposed recently to study the computational power of semidefinite programming, a problem in optimization theory. It turns out that it...
