SoftBank Corp. (“SoftBank”) and LQUOM, Inc. (“LQUOM”) launched a trial to study the communication of entangled photons as a step toward realizing a quantum Internet. The field study will transmit entangled photons through optical fiber in the Tokyo Metropolitan Area. The optical fiber of this study links SoftBank’s headquarters and its data center in the Tokyo Metropolitan Area. LQUOM will integrate a quantum communication system with the field fiber. Accordingly, SoftBank and LQUOM will investigate quantum communication technology in a practical environment in the Tokyo Metropolitan Area.

SoftBank aims to realize a hybrid network that encompasses existing Internet and quantum Internet technologies as future infrastructure to support the quantum era. LQUOM has been developing quantum communication technologies with a view toward realizing a quantum Internet. SoftBank and LQUOM will investigate fundamental technologies for a quantum Internet, consider practical use cases for a quantum Internet, and contribute to advanced network infrastructure of the future.
