Proof-of-Concept Passes Quantum Keys from End-to-End Over Photonic Network Spanning Heart of Chicago to NW Indiana CHICAGO (Dec. 9, 2025) — Quantum Corridor, in collaboration with Toshiba International Corporation and…

3rd June 2025 – Purdue University School of Nuclear Engineering, in collaboration with the Department of Energy’s Oak Ridge National Laboratory (ORNL) and Toshiba, has successfully completed the demonstration of…

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.

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…

LONDON, 5 July: HSBC is the first bank to join BT and Toshiba’s quantum-secured metro network – connecting two UK sites using Quantum Key Distribution (QKD) to prepare its global…

This paper covers a commercially-ready QKD metro network built in London, complete with customer access tails and an aggregated central metro node, able to support multiple customers. The solution includes a full Key Management System; encrypted classical Ethernet data on the same fibre and a Data Communications Network (DCN) for full remote monitoring at BT’s Network Operations Centre (NOC).

Toshiba and Orange demonstrate the viability of deploying Quantum Key Distribution (QKD) on existing commercial networks to protect transmissions from quantum computers

This article describes experimental research studies conducted toward understanding the implementation aspects of high-capacity quantum-secured optical channels in mission-critical metro-scale operational environments using quantum key distribution (QKD) technology.

Discover how multiplexing can help you to easily integrate quantum-safe technologies into your existing telecoms infrastructure without dedicated fibres

The power of quantum computing technology can challenge the security of any system reliant on certain mathematical algorithms, meaning it could undermine the security that blockchain promises. Quantum Key Distribution is the answer. This paper will explore the evolution of QKD, its future, and a real-world application research study with Toshiba, JPMorgan Chase and Ciena.
