Toshiba Corporation is a Japanese multinational conglomerate corporation headquartered in Tokyo, Japan. Its diversified products and services include information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, household appliances, medical equipment, office equipment, lighting and logistics.Toshiba was founded in 1938 as Tokyo Shibaura Electric K.K. through the merger of Shibaura Seisaku-sho and Tokyo Denki . The company name was officially changed to Toshiba Corporation in 1978. Toshiba has made numerous corporate acquisitions during its history, including of Semp in 1977, of Westinghouse Electric Company in 2006, of Landis+Gyr in 2011, and of IBM's point-of-sale business in 2012.Toshiba is organised into four business groupings: the Digital Products Group, the Electronic Devices Group, the Home Appliances Group and the Social Infrastructure Group. In 2010, Toshiba was the world's fifth-largest personal computer vendor measured by revenues . In the same year, it was also the world's fourth-largest manufacturer of semiconductors by revenues .Toshiba is listed on the Tokyo Stock Exchange, where it is a constituent of the Nikkei 225 and TOPIX indices, the Osaka Securities Exchange, the Nagoya Stock Exchange and the London Stock Exchange.

Energy sustainability is key to future mobile networks due to their foreseen capacity upsurge. The objective of the ETN SCAVENGE (Sustainable CellulAr networks harVEstiNG ambient Energy) is to create a training network for early-stage researchers (ESRs) who will contribute to the design and implementation of eco-friendly and sustainable next-generation (5G) networks and become leaders in the related scientific, technological, and industrial initiatives. Sustainable networks are based on the premise that environmental energy can be scavenged through dedicated harvesting hardware so as to power 5G base stations (BSs) and the end devices (mobile terminals, sensors and machines). To realise this vision, the project will take a complete approach, encompassing the characterisation of intermittent and/or erratic energy sources, the development of theoretical models, and the design, optimisation and proof-of-concept implementation of core network, BS and mobile elements as well as their integration with the smart electrical grid. The consortium is composed of world-class research centres and companies that are in the forefront of mobile communication and renewable energy research and technology development. The attitude of the industrial partners towards the strong investment in R&D and their strategic vision are fully aligned with the mission of this project, making them perfectly fit for this consortium. This grants a well-balanced project with genuine and strong technical interactions. The ESRs will have a unique opportunity towards professional growth in light of dedicated cross-partner training activities and through the interaction with the Partner Organisations, which also include relevant stakeholders in the envisioned market. All of this will ensure that the trained researchers will be successfully employed at the end of the research program.

Security in quantum cryptography is continuously challenged by inventive attacks targeting the real components of a cryptographic set-up, and duly restored by new countermeasures to foil them. Owing to their high sensitivity and complex design, detectors are the most frequently attacked components. It was recently shown that two-photon interference from independent light sources can be used to remove any vulnerability from detectors. This new form of detection-safe quantum key distribution (QKD), termed measurement-device-independent (MDI), has been experimentally demonstrated but with modest key rates. Here, we introduce a new pulsed laser seeding technique to obtain high-visibility interference from gain-switched lasers and thereby perform MDI-QKD with unprecedented key rates in excess of 1 megabit per second in the finite-size regime. This represents a two to six orders of magnitude improvement over existing implementations and supports the new scheme as a practical resource for secure quantum communications. © 2016 Nature Publishing Group

The Broadband Wireless Forum (BWF) was established in Japan under the guidance of the Ministry of Internal Affairs and Communications, Japan, to enhance future wireless technologies through collaboration involving industry, government, and academia. Wireless power transfer (WPT) is one of the key technologies expected to lead to the emergence of new business fields in the near future. In this context, the Wireless Power Transmission Working Group (WPT-WG) was formed in BWF to discuss problems concerning the commercialization of WPT technologies. In this paper, issues and initiatives of WPT-WG are presented. © 1963-2012 IEEE.

Obtaining substantial nonlinear effects at the single-photon level is a considerable challenge that holds great potential for quantum optical measurements and information processing. Of the progress that has been made in recent years one of the most promising methods is to scatter coherent light from quantum emitters, imprinting quantum correlations onto the photons. We report effective interactions between photons, controlled by a single semiconductor quantum dot that is weakly coupled to a monolithic cavity. We show that the nonlinearity of a transition modifies the counting statistics of a Poissonian beam, sorting the photons in number. This is used to create strong correlations between detection events and to create polarization-correlated photons from an uncorrelated stream using a single spin. These results pave the way for semiconductor optical switches operated by single quanta of light. © 2016 Nature Publishing Group

This paper proposes a distributed framework for demand response and user adaptation in smart grid networks. In particular, we borrow the concept of congestion pricing in Internet traffic control and show that pricing information is very useful to regulate user demand and hence balance network load. User preference is modeled as a willingness to pay parameter which can be seen as an indicator of differential quality of service. Both analysis and simulation results are presented to demonstrate the dynamics and convergence behavior of the algorithm. Based on this algorithm, we then propose a novel charging method for plug-in hybrid electric vehicles (PHEVs) in a smart grid, where users or PHEVs can adapt their charging rates according to their preferences. Simulation results are presented to demonstrate the dynamic behavior of the charging algorithm and impact of different parameters on system performance. © 2010-2012 IEEE.
