Toshiba has been awarded a quantum-based network development contract by the National Institute of Information and Communications Technology (NICT).The network will be based on a quantum key distribution (QKD) model.

It’s currently working on quantum cryptography projects involving Verizon and the UK’s BT Group. The company’s endeavor, as relayed by its top brass, is to provide unhackable quantum-based communication solutions to telecommunication clients.

Its quantum computing segment targets vulnerable sectors such as finance, health care, and defense. Quantum key distribution (QKD) technology will be used to connect trusted remote partners through a dedicated network that utilizes photon technology for security.

Quantum technology uses the behavioral properties of photons and electrons to secure data. It also leverages these elements to speed up information processing.

The technology is among the next frontiers in data security. As such, major US tech behemoths such as IBM, Microsoft, and Google are already involved in related projects.

The rapid development of quantum processing capabilities is currently critical to network security, especially now that state actors such as Russia and China are getting involved. The primary weakness of conventional networks is that data transmitted can be easily intercepted and decrypted using futuristic brute-force decryption algorithms run by powerful quantum computers. This drives the need for quantum-based distributed-key solutions.

There are fears that the current advances in quantum computing will make current encryption methods obsolete.
