Quantum Computing from Hype to Game Changer
Hiroyuki Mizuno
Abstract
This paper describes the current state of quantum computer development in the world (including the hype) from three perspectives and introduces our research and development of quantum computers. The first is the complex market structure. While investments in quantum computers are increasing, these investments do not always immediately bring value to consumers, and this delay results in hype. CMOS annealing technology to fill this delay is described. The second is the accountability of the impact produced by a quantum computer that does not yet exist. This paper discusses why so many people continue to question the value of quantum computers despite their clear applications, and our struggles. The third is technology development, which includes many research aspects. This paper introduces our top-down approach that takes full advantage of semiconductor technologies. Some of our activities including “Shuttling qubit” for the next milestone in the development of silicon quantum computers, which is qubit operation in a scalable qubit array structure, are also described.
