On January 24, 2020, KCG, KCGI and the Kyoto Small and Medium Enterprise Technology Center held the Kyoto Information Industry Association New Year Seminar, which was sponsored by the Kyoto Information Industry Association, chaired by Mr. Wataru Hasegawa, chairman of the KCG Group, which includes Kyoto Computer Gakuin (KCG) and Kyoto College of Information and Graduate Institute of Technology (KCGI), and co-sponsored by KCG, KCGI and the Kyoto Small and Medium Enterprise Technology Center.The lecture was titled "Quantum Computers and Their Applications" and covered the principles of quantum computers, which are currently being developed by companies around the world, and their applications to solving various problems facing modern society.

Dr. Nakamura explained the principle and characteristics of quantum computers, saying that while conventional computers calculate with 0 or 1, quantum computers calculate probabilistically by superimposing 0 and 1, and are not general-purpose computers that can be used for any purpose, but rather computers that excel at solving "combinatorial optimization problems" such as those that seek the "maximum value" or "minimum value" from among vast combinations of data.As examples of familiar applications, he cited preliminary simulations of drug synthesis, minute-by-minute instructions to a large number of taxis on traffic congestion circuits, and the creation of work schedules with various restrictions on salary and qualifications.The current issue is that quantum superposition, which is a phenomenon that does not exist in nature, can finally be realized near absolute zero (minus 273 degrees) and disappears even with a small amount of noise, so the challenge is to develop technology to generate this state on a large scale in a sustained manner.The audience of KCG and KCGI students listened with great interest to Dr. Nakamura's lecture, in which he explained the mysterious mechanism of quantum computers using easy-to-understand analogies.
