a photon emitted by it. Work on exciton-polaritons continued. Since 2012, Yamamoto has studied the required number of physical qubits and expected computational time in a gate-model fault-tolerant quantum computer and pioneered the development of a novel quantum/classical hybrid computer, called coherent Ising machine inspired by developments in digital coherent optical communications and degenerate optical parametric oscillators. Awards Yamamoto is a fellow of the Optical Society of America (now Optica), the American Physical Society, and the Japan Society of Applied Physics. In 1985, Yamamoto received the Achievement Award of the Institute of Electronics, Information and Communication Engineers (IEICE) of Japan on his early work on coherent optical communications. In 1992, he received the Nishina Prize and the Carl Zeiss Award on his pioneering work on squeezed state generation in semiconductor lasers. In 2000, he received the IEEE LEOS Quantum Electronics Award and the Matsuo Science Prize. In 2005, he received the Medal of Honour with Purple Ribbon from the Government of Japan. In 2010, he was the Hermann Anton Haus Lecturer at MIT and gave a lecture on exciton-polariton condensation. In 2011, he received the Okawa Prize on his pioneering work on single photon generation from a quantum dot. In 2022, he received the Willis Lamb Award on his pioneering work on coherent Ising machines.
