A quantum memory capable of storing photons
Photons are quantum particles travelling at the speed of light: they enable ultra-fast data transfers. The data transferred by optical fiber are already encrypted by sequences of photons. A team of the university of Basel made an additional step by developing a quantum memory capable of storing a single photon. The researchers managed to store photons in an atomic gas and read them later without altering their quantum properties. The whole controlled simply by laser.
This high-speed storage technology could turn out very useful in the future quantum Internet ahead of us. As all quantum technologies, it is still in the early stages but the results of the Swiss team are promising because the technology used does not require cooling system nor vacuum equipment. It could then be implemented in a simple and compact setup.
