  • Achieving the world's highest rate of quantum encryption key data distribution (Sep. 2014) Toshiba Corporation will today announce the world's highest speed quantum encryption system. The new quantum key distribution device was installed over a 45 km optical fiber between Otemachi in central Tokyo and Koganei on the cities western outskirts, and tested over a continuous 34 day period in collaboration with Japan's National Institute of Information and Communications Technology (NICT). During this time the system achieved world records in both the total amount of secure key data (878 Gbit) and the speed of transmitting the key data (25.8 Gbit per day average) for an installed system, while remaining stable and completely autonomous. These breakthroughs will be announced at the QCrypt 2014 conference, to be held on September 1 – 5.

  • Development of an embedded non-volatile memory technology for low-power and high-performance FPGAs (Jun. 2014) Toshiba has developed a technology by which a flash memory and CMOS transistor are adjacently integrated each other in the same chip. This technology enables the creation of non-volatile FPGAs with high performance and lower power consumption. Details of the technology were presented at the VLSI Technology Symposium, an international conference on semiconductor devices in Honolulu, Hawaii on June 12 (local time).

  • Development of an SoC aggressive power-saving control technology for ultra-low power consumption platforms (Apr. 2014) Toshiba has developed a control technology that realizes significant power savings by aggressively transiting the core device SoC (System on Chip) of battery-operated information devices to the power-saving mode. We tried this technology on a test model loaded with electronic paper (a type of battery-operated information device) and found that the power consumption was reduced by up to one-fifth. The details of this technology were presented at CoolChips 2014 held in Yokohama from April 14 to 17.

  • Toshiba has developed a 7-kW contactless charger for electric vehicles (EVs) that meets the requirement for a wider range of car types (Mar. 2014) It is a bother to plug and unplug the connector of a conventional wired charger for plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs). To address this problem, Toshiba has developed an easy-to-use and safe contactless EV charger. The new contactless charger can transmit electric power over a distance of 17 cm, accommodating the requirement for high-bodied minivans. The charger has been tested in combination with a battery controller mounted on an electric vehicle. The test has verified that the charger has a capacity of 7 kW. Thus, it will halve the charging time, compared to 3-kW-class wired on-board chargers that are most widely used in Japan. The permissible right-left misalignment between the transmitting and receiving pads is up to 25 cm. This will ease the strain on drivers for parking accurately, compared to comparable chargers from other vendors that tolerate a misalignment of only up to 15 cm.
