Development of a ``qubit'' that has the ability to correct calculation errors caused by malfunctions, which are essential for the practical application of next-generation computers ``quantum computers'', by putting pulses of light into a special state. The University of Tokyo and others announced that it was a success. This achievement is said to be a major step forward toward the practical application of quantum computers that use light.
Quantum computers, which are expected to be the next generation of computers due to their extraordinary computational power, are susceptible to noise from the surrounding environment and can cause malfunctions. Providing a "correction" function is considered to be one of the essential issues for practical application.
A research team led by Professor Akira Furusawa of the University of Tokyo, who is conducting research on quantum computers that use light, is creating error correction in the quantum bits that perform calculations by putting pulses of light into a special state. They published a paper in an American scientific journal stating that they had succeeded in providing the ability to do this.
If the "error correction" function of this "qubit" can be further improved, it will be possible to reduce calculation errors much more efficiently than other types of quantum computers, and in the future quantum computers using light will become practical. This means that you can expect to raise your level.
Professor Furusawa of the research team said, ``This is a paradigm shift that demonstrated a completely new method, and a milestone in the development of optical quantum computers.''
