Biography
Yamamoto was born in Tokyo on November 21, 1950. In 1973 he got his B.S. degree from the Tokyo Institute of Technology. He continued his studies at the University of Tokyo where he earned a M.S. in 1975 and a Ph.D. in 1978. Since 1992 he is a professor of applied physics and electrical engineering at Stanford University in the United States. Since 2003 he also has professorships at the University of Tokyo and the National Institute of Informatics in Tokyo.
Work
Yamamoto's scientific focuses in the 1980s were optical fiber communications, semiconductor lasers, quantum non-demolition measurement and quantum optical effects. His most prominent work in the 1990s is in semiconductor quantum optics (especially involving microcavities and quantum wells) and quantum effects and noise in electronic devices.
During the 2000s, his most prominent work was on the development of optically-active quantum dots as a platform for quantum information processing (both as single-photon sources for quantum cryptography, and as hosts for spin qubits), and his work on exciton-polaritons,. Yamamoto was also active in the development of both theory and realization of quantum key distribution protocols. Landmark papers from this era include the demonstration of indistinguishable photons from a single quantum dot; the proposal for biexciton cascade as a method for generating entangled photons (for QKD) from a single quantum dot (this is the proposal underlying essentially all QD entangled-photon sources, such as those reviewed in ), and demonstration of control of a single spin qubit in a quantum dot using optical pulses.
During the 2010s, his work has continued on exploring quantum dots as a platform for building both quantum repeaters and quantum computers. One highlight was the co-first demonstration (with Ataç İmamoğlu's group) of entanglement between a spin in a quantum dot and a photon emitted by it. Work on exciton-polaritons continued, and since 2012, Yamamoto has pioneered the development of an optical computer, inspired by developments in quantum annealing and adiabatic quantum computing.
