Quantum Journal Club: Experimental Passive Round-Robin Differential Phase-Shift
Abstract: In quantum key distribution (QKD), the bit error rate is used to estimate the information leakage and hence determines the amount of privacy amplification—making the final key private by s...

Quantum Journal Club: Quantum Dynamics with Spatiotemporal Control of Interactio
Abstract: Optical control of atomic interactions in quantum gases is a long-sought goal of cold atom research. Previous experiments have been hindered by rapid decay of the quantum gas and parasitic ...
