Quantum Information Group

Quantum Communication Research explores disruptive protocols and technologies to securely exchange information between remote parties, which will remain secure even after the advent of the quantum computers that will be capable of breaking classical encryption methods. We use Quantum Key Distribution (QKD) to securely share encryption keys utilizing the unique properties of quantum mechanics to alert for the presence of an eavesdropper.

Applications in quantum information technology, such as quantum cryptography and quantum computing, require new devices that generate and detect light at the quantum level. Toshiba have developed technology for single photon generation and detection using semiconductor structures.

The Quantum Technology Business Unit builds secure communication products underpinned by quantum physics and rigorously tested in field trials around the world. These commercial quantum secure products are designed to allow seamless integration into today’s network architectures, thus paving the way to straightforward adoption of quantum secured technology by customers.
