Prof. Shigeki Takeuchi of the Research Institute for Electronic Science was awarded the 6th Japan Society for the Promotion of Science (JSPS) Prize at a ceremony held on March 1. He was recognized for his outstanding contribution to the realization of quantum information processing and communication using photons. The JSPS Prize was established by the Japan Society for the Promotion of Science in order to raise the level of scientific research in Japan to the world's highest standard. Its specific goals are to recognize and support young researchers that show high creativity and superlative research abilities by sustaining their motivation with support in order for them to move forward in their work. Utilizing the basic principles of quantum mechanics, quantum computers can solve some kinds of problems which are too hard even for today’s supercomputers. Prof. Takeuchi proposed and successfully developed a test bed for a quantum computation algorithm using photons, which is one of the examples of the application of basic principles of quantum mechanics to information processing. He also successfully developed an optical quantum circuit `an entanglement filter’ that enables the extraction of photon pairs based on the correlation between their polarizations (i.e., quantum entanglement - a central concept of quantum mechanics). He also succeeded in beating the standard quantum limit for the sensitivity of optical phase measurement by using four entangled photons. His achievements are expected to lead to the implementation of quantum information processing using photons and revolutionize technologies for quantum computing, quantum cryptography communications, and optical measurement. There are also high hopes for continued research progress in quantum information processing and communication. Contact information:
