Toshiba has worked with US bank Wells Fargo and other partners to test a fully operational QKD deployment that demonstrates how different products and technologies can successfully work together to provide quantum-secure communications.

Quantum Key Distribution (QKD) technology offers a powerful way to securely transmit data without risk of decryption, even by quantum computers. But integrating the technology into existing telecommunication networks has previously posed problems for deployment and compromised performance – until now. This whitepaper outlines how Toshiba technology enables businesses to easily integrate quantum-safe technologies into existing telecoms infrastructure without dedicated fibres.

Toshiba researchers have demonstrated a new network architecture for global-scale information-theoretic secure communication, combining QKD and Distributed Symmetric Key Establishment (DSKE), including the extension of draft emerging standards for vendor-interoperable quantum key relay (ETSI 020).

Toshiba has deployed Hungary's first multi-node Quantum Key Distribution Network, providing an blueprint for other operations taking part in the EuroQCI initiative to protect communications in Europe from quantum-based attacks.

A trackside fibre communication link in the Czech Republic has recently been upgraded to a quantum-secure connection using Toshiba’s multiplexed QKD technology. Despite heavy railway traffic in close proximity, the…
