Development of Entangled Photon Sources

NEXT
PREV
Features

The quantum information and communication technology (QICT) is expected to overcome the difficulties that classical information technology is confronted with. Quantum entanglement carried by photons is one of the most fundamental resources in QICT. We have been developing efficient, high-quality entangled photon sources utilizing semiconductor materials and quasi-phase-matched optical nonlinear devices, with a number of patents awarded.

Targeted Application(s)/Industry

We hope to conduct collaborative research with a willing company for a practical application of this technology.

DIFFERENTIATION INDUCING METHOD ENABLING TUMORIGENESIS OF IPS CELLS TO BE SUPPRESSED

Features

The present invention relates to a technique for differentiating iPS cells into target differentiated cells while suppressing tumorigenesis in the iPS cells. In use of a statin and a differentiation inducer, iPS cells are differentiated into target differentiated cells, whereby iPS cells can be differentiated into differentiated cells in which tumorigenesis is suppressed.

Method for efficient production of induced pluripotent stem cells utilizing cells derived from oral mucosa

Features

We provide a technique which can produce induced pluripotent stem (iPS) cells with high establishment efficiency and imposes lower burden on patients. iPS cells can be produced efficiently with significantly increased establishment efficiency by selecting cells derived from the oral mucosa and introducing a reprogramming factor, which can induce the reprogramming of the cells into pluripotent stem cells, into the cells.

Novel-Concept Silicon Integrated Circuits Derived from the 3-Dimensional Device, Circuit and Architecture

NEXT
PREV
Features

In recent year, facing the age of nanoscale engineering, the new technologies of device, circuit and architecture supported by novel physical guidance principles are highly expected, just as the similar situation as the predawn of semiconductor technology when Bardeen and Shockley discovered the secret of transistors. Therefore, in our research approach, the architectures, circuits, devices and CAD design tools for nanoscale LSI are systematically investigated in the following three main research subjects.
1. Study on nanoscale device and circuit
Aiming at the nanoscale silicon semiconductor integrated circuit, we are mainly working on the following directions for new devices and circuits:
①Analysis for novel physical phenomenon based on nanostructural effects
②Device and circuit technology with new operating principle
③Restraint technology for increasing variability of device characteristics
④Architecture and circuit technology for robust information processing
2. Study on the 3-dimention-structual device and circuit
The elementary element of recent LSI with planar-structural devices is coming close to the physical limitation of scaling. In order to break the limit and sustain the evolution of future LSI performance, we have started the research on the novel 3-dimension-structural devices and circuits.
3. research on wireless integrated circuit (IC) based on information transmission
The ultracompact lightweight wireless IC is one of essential technologies for realizing the ubiquitous society which has the network available in anywhere, at anytime and from any surrounding items. For example, the IC tags for receiving information with reading function are getting close to the practical applications. In our laboratory, aiming at the automatic operating wireless IC with embedded power supply, we are systematically working on the following directions:
①The electrical power generation and storage devices
②Devices and circuits with Ultralow power consumption
③Sensing devices
For all above subjects, We hope to conduct collaborative researches with companies interested in our research.

Features

Integrated electronic systems are a fundamental technology that makes possible the lifestyles of ease and abundance we enjoy in the modern world. By leveraging innovative core technologies and longstanding accomplishments of industry-academic cooperation in Tohoku University as centripetal forces, we have promoted the CIES Consortium consisting of industry–academic collaborations, major national projects and community-based cooperation projects in the fields of Spintronics, AI hardware and Power Electronics through our cooperation with a diverse range of Japanese and foreign companies from fields such as materials, equipment, devices, circuits and systems. CIES has promoted world level Academic-Industrial Collaboration under establishment of world-first 300mm wafer process line and facilities for prototype manufacturing and characterizing spintronics integrated circuits compatible with world-class companies in university campus.

Targeted Application(s)/Industry

CIES has conducted international industry-academic collaboration in the fields of integrated electronic technologies ranging from materials/equipment to devices/systems. In addition, we have promoted to cooperate with regional and local companies with support of local government (Miyagi Prefecture, Sendai City, Iwate Prefecture, etc) for contributing to Tohoku reconstruction and regional development. We welcome your participation in CIES consortium.
