Yasunobu Nakamura
Education and early work. While a child, Nakamura's family moved from Osaka to Hinode, Tokyo, where he would gain his early education. He obtained his Bachelor of Science (1990), Master of Science (1992), and Ph.D. (2011) degrees at the University of Tokyo. In 1999, as a researcher at NEC, Nakamura and collaborators Yuri Pashkin and Jaw-Shen Tsai demonstrated "electrical coherent control of a qubit in a solid-state electronic device" and in 2001 "realized the first measurement of the Rabi oscillations associated with the transition between two Josephson levels in the Cooper pair box" in a  configuration developed by Michel Devoret and colleagues in 1998. In 2000, Nakamura was featured as a "Younger Scientist" by the Japan Society of Applied Physics for his work at NEC in "quantum-state control of nanoscale superconducting devices." From 2001-2002, he visited the group of at TU Delft on a sabbatical from NEC, where he worked with Irinel Chiorescu, Kees Harmans, and Mooij to create the first flux qubit. In 2003, he was named one of MIT Technology Review's top innovators under 35 years old, in which editors noted that "Nakamura and a collaborator got two qubits to  interact in a manner that had been predicted but never demonstrated" at the time. Current work. , the Japan Science and Technology Agency (科学技術振興機構) announced funding for Nakamura's work through their Exploratory Research for Advanced Technology (ERATO) program. The project, entitled Macroscopic Quantum Machines, seeks to dramatically improve quantum state control technology to further the field of quantum computing. Of principal focus is the development of a highly scalable platform for implementing quantum information processing techniques, as well as the creation of hybrid quantum systems which interface with microwave quantum optics. In an article in in 2018, it was announced  that work towards the construction of a quantum computer with 100 superconducting qubits was underway. In 2019, the Japanese Ministry of Education, Culture, Sports, Science and Technology launched a quantum technology project known as QLEAP, with Nakamura as the team leader for the quantum information processing component. The project aims to develop superconducting quantum computers and other quantum technologies over a ten-year period, by increasing collaboration between academia and industry. More recently, results have been published in which superconducting qubits were used to resolve quanta of magnon number states, to create a quantitatively non-classical photon number distribution, to  measure fluctuations in a surface acoustic wave (SAW) resonator, and to measure an itinerant microwave photon in a quantum nondemolition (QND) detection experiment. A superconducting circuit was later used to realize information-to-work conversion by a Maxwell's demon, radio waves and optical light were optomechanically coupled to surface acoustic waves, and an ordered vortex lattice in a Josephson junction array was observed. Nakamura has spoken several times at quantum information science conferences and seminars, including at the University of Vienna, the Institute for Theoretical Atomic Molecular and Optical Physics at Harvard University, the National Center of Competence in  Research's Quantum Science and Technology Monte Verità conference, the Institute for Quantum Computing at the University of Waterloo, the Institute for Molecular Engineering at the University of Chicago the Institute for Quantum Optics and Quantum Information (IQOQI), and the Yale Quantum Institute at Yale University. In 2020, Nakamura was named as a fellow of the American Physical Society for "the first demonstration of coherent time-dependent manipulation of superconducting qubits, and for contributions to the development of superconducting quantum circuits, microwave quantum optics, and hybrid quantum systems".
