University of Tokyo and Fujitsu show first single-photon emission in data transmission wavelengths

The University of Tokyo's Nanoelectronics Collaborative Research Center and Fujitsu Laboratories Ltd. today announced the joint development of technologies that generate and measure single-photons, succeeding in observing the world's first emission of single-photons in data transmission wavelengths.

The newly developed technologies pave the way for accelerating speeds for quantum encryption data transmission, considered the ultimate method of encrypted transmission, to 400 times faster than the data transmission speeds of conventional quantum encryption that could only transfer data at a few hundred bits per second (bps). The technologies represent a major step forward towards the practical application of quantum encryption data transmission.

Details of the new technologies will be presented at The 27th International Conference on the Physics of Semiconductors (ICPS-27) to be held in Arizona, U.S. from July 26.
