  • Toshiba verifies a system for distributing quantum encryption keys between multiple transmitters and a single receiver for the first time in the world (Sep. 2013) Quantum encryption key distribution is a cryptographic technology which ensures data security by utilizing the quantum mechanical properties of photons. Previous research and development of quantum encryption key distribution has been conducted using a system for connecting one transmitter with one receiver. However, for the first time in the world the Cambridge Research Laboratory of Toshiba Research Europe has succeeded in testing and verifying a technique for distributing quantum encryption keys using a system connecting one receiver with multiple transmitters (quantum access network) based on its own high-speed photon detection technology. This result was published in Nature, one of the most prestigious scientific magazines in the world.

  • Development of a technology for automatic localization of the cardiac area and diaphragm from a chest 3-D MRI (Feb. 2013) Toshiba, together with Toshiba Medical Systems Corporation, has developed a technology which automatically localizes the cardiac area and diaphragm from a 3-D MRI image of the entire chest area, and confirmed its accuracy in cooperation with Kyorin University Hospital. The technology eliminates complicated procedures required in coronary artery examinations such as determining the location of the heart. This technology was presented at the 16th Annual Society of Cardiovascular Magnetic Resonance (SCMR) Scientific Sessions, the world’s largest conference on cardiac magnetic resonance imaging, held in San Francisco, U.S.A.

  • Use of single fiber achieved through quantum encryption key technology and data wavelength multiplexing (Jan. 2013) Quantum encryption key distribution is a cryptographic technology which ensures data security by utilizing the quantum mechanical properties of photons. In the past, encryption keys made of ultra-weak photons were transmitted through dedicated fiber instead of fiber that transmits optical communication data equivalent to about one million photons per bit. The Cambridge Research Laboratory (CRL) of Toshiba Research Europe succeeded in transmitting optical communication data and encryption keys at the same time through a single fiber by multiplexing encryption key photons having a different wavelength from that of optical communication data. The achievement was published in Physical Review X (November 20, 2012), an on-line version of Physical Review, the most prestigious publication in the U.S. physics community.
