As competition for development intensifies with China and other countries, we would like to partner with major European and American telecommunications companies to take over most of the world.
Toshiba has officially announced that it will commercialize this quantum encrypted communication in Japan, Europe and the United States next year.
In Japan, we have received an order from the government as a security measure for communication networks, and this is the first commercialization in Japan.
In terms of overseas marketing, we have partnered with “British Telecom” in the UK and “Bellaison Communications” in the US.
International competition for quantum crypto is intensifying, with China’s policy to spread it across the country by 2025.
Toshiba has been leading research and development and the number of patents in this field is the largest in the world, but we aim to be the first to develop business in Japan and abroad and have the largest share in the world.
Why can’t you figure it out?
Currently, commonly used ciphers are made up of a combination of numbers called “prime numbers,” and it has been noted that the risk of being cracked increases as the computing power of the computer increases dramatically.
In these circumstances, “quantum cryptography” is attracting attention for being “absolutely unbreakable” with any computer.
The “quantum code” is a technology that applies the “quantum mechanics” of physics that shows the movement and behavior of extremely small substances such as the “photon”, which is the smallest unit of light.
Apart from the encrypted data
We will send you the information that will be the “key needed to crack the code.”
According to Masahiro Takeoka, director of the Information and Communication Research Organization, which has been working in quantum cryptography for many years, the characteristic is that this “key” information is divided and sent in each “photon”.
According to quantum mechanics, the state of the “photons” changes when they are observed, so the moment someone steals the information from the “key”, the state of the “photons” changes, which is why it was stolen. You can notice it.
With this technology, when it is detected that it has been stolen, that information is automatically invalidated and a new key is automatically recreated using only the remaining information that has not been stolen.
Director Takeoka said that Japan is the world leader in the field of quantum cryptography. “Europe, the United States and China are competing with development, but Toshiba products have the ability to send ‘key’ information. It is many times higher than the previous ones and has the highest reliability in the world. which is a new technology, the problem is how to incorporate it into society, and in Japan, we are the first in the world to work on a demonstration experiment to protect medical information. In the future, it will be necessary to cooperate with the infrastructure business of communications to turn it into a business. “
Toshiba “The best standard in the world”
Mr. Murai said that it is at the highest level in the world in terms of communication speed and stable communication distance, and said, “From the point of handling extremely confidential information such as government agencies, financial institutions or medical institutions. I think We will get in. Ultimately, we would like to aim to provide services on a broad range nationwide. “
Intensification of competition for development in the world
Therefore, in the future, to protect highly confidential information not only from private enterprise but also from national security aspect, “quantum cryptographic communication” which is absolutely unbreakable using quantum is said to be indispensable. Toshiba expects the global market to exceed 2 trillion yen by 2035.
In these circumstances, China has already put it into practice in the fields of finance and justice, and is making efforts to spread it throughout China by 2025. Furthermore, South Korea is also a Swiss company whose local telecommunications giant has quantum cryptographic communication technology. International competition for development, such as the acquisition and commercialization of.
Secretary General Kato “Important Technology to Support Future Economic Society”
At a morning press conference, Secretary of State Kato said: “‘Quantum cryptographic communication’ has been promoting research and development as an important technology that will support the future economic society, and related domestic companies, including Toshiba. , they are participating in this. I know it is an important security technology and I would like to continue to support research, development and practical application. “
