Ultraviolet emissions from the magnetic footprints of Io, Ganymede and Europa on Jupiter.

abstract：:Interfacing a single photon with another quantum system is a key capability in modern quantum information science. It allows quantum states of matter, such as spin states of atoms, atomic ensembles or solids, to be prepared and manipulated by photon counting and, in particular, to be distributed over long distances. S...
