In the future, our society and our lives will become even more reliant on networks, so it will be vital that information is transmitted quickly and safely. However, the rise of quantum computers, with their overwhelming computational capabilities, will pose a threat to the security of cryptographic communications. Hopes are high for quantum key distribution as a method of secure encrypted communication. According to information theory, quantum key distribution, which uses the principles of quantum mechanics, is an unbreakable form of encryption.
Toshiba is leading the world in developing unique technologies for accelerating and stabilizing quantum key distribution. In this running feature, we'll explain this technology over the course of several articles.
