<About the Research>
Quantum computers are now attracting much attention as next-generation computers. We are developing an optical quantum computer based on our original method and exploring real-world applications of our technology.
A quantum computer is a computer with a new computational principle that utilizes quantum mechanics, the physical laws of the microscopic world, in its calculations. Quantum computers are expected to be applied to various fields such as the development of new materials and drugs, optimization problems such as route search for car navigation systems, and performance improvement of artificial intelligence. We are working on the realization of a quantum computer using photons, the smallest unit of light. This is because the unique properties of photons make it possible to realize an all-around quantum computer that can operate at room temperature and in the atmosphere, can run at high clock speeds, and can even be used for optical communications. In addition to quantum computers, photons open up a variety of new possibilities for information processing. For example, photons can be used for absolutely unbreakable cryptographic communications, high-capacity communications that exceed conventional physical limits, and improved sensitivity in biological imaging and gravitational wave telescopes. Thus, in the field of optical quantum information processing, which is my specialty, we can enjoy the pleasure of experiencing the physical laws of the microscopic world of light, controlling them with engineering techniques, and creating new value. It is an exciting field of research that is full of the true joy of “applied physics.”
Thus far, we have developed a method to efficiently perform calculations using photons, and proposed an original scheme for optical quantum computing. In the future, we will work on the development of optical quantum computers using our original approach and explore practical applications using the technology.


<Future aspirations>
In the field of quantum computers, where the competition for the development is heating up all over the world, we believe that Japan can lead the world in the field of optical quantum computers. We aim to realize the world's first practical quantum computer originating from Japan by taking a unique approach.
