Toshiba started basic research into quantum cryptographic communication in 2003, and Toshiba Research Europe Ltd. in Cambridge, UK, led the world in transmission of 1 megabit of quantum cryptographic keys a second in 2010. In 2014, Toshiba achieved stable communication of quantum keys for 34 days over standard optical fiber(Note 1).Toshiba aims to use the results of the current verification testing to support commercialization within five years of a quantum cryptographic communication system able to guarantee secure transfers of confidential information and personal information. Potential users will include public agencies and medical institutions.

(Note 1) Part of the research results is derived from the "Research and Development on Secure Photonic Network Technology" outsourced to the National Institute of Information and Communications Technology (NICT).
