Researchers at MIT have managed to demonstrate an atomic quantum memory that can detect the polarization of a photon (“polarization quantum bit”), generate a signal announcing successful storage of the information, and generate a second photon with the same polarization whenever the system receives the instruction to read the information, in what is a key… »

A team of physicists and engineers at Bristol University has demonstrated exquisite control of single photons on a silicon chip to make a major advance towards quantum technologies, including super-powerful quantum computers and ultra-precise measurements. Jeremy O’Brien, Director of the Centre for Quantum Photonics at the Bristol University, who led the research, has demonstrated precise… »
