Quantum Key Distribution
The new age of secure communication, powered by quantum physics
Our vision is to secure the world’s communications from the threats posed by advances in computing and mathematics. At a time when technological progress has created an almost constant state of data proliferation, the need for the secure transmission of sensitive information has never been more significant. It is essential to protect and future-proof data communication now through the advancement of reliable and ultra-secure quantum cryptography solutions.
At Toshiba, we are committed to delivering world’s leading cyber-physical-system technology to protect the private information of citizens and companies. Our Quantum Key Distribution (QKD) offering applies the fundamental laws of Quantum Physics to secure network communications. Based on decades of scientific research, our industry leading approach to information technology provides organizations with the ability to revolutionize their IT infrastructure with the most secure communications known today.
What is QKD
Keeping data safe and secure is one of the greatest challenges posed by the rapid development of today’s information technology. More and more sensitive data is stored on remote computer servers, for example in the cloud, making secure access to this data a predominant concern. Securing the transmission and retrieval relies on encryption of information sent over public networks.
Quantum Key Distribution
Quantum key distribution is gaining momentum to deploy and implement in real world use cases to prepare for threats brought by quantum computers. Toshiba’s quantum cryptography solutions support the safety and security of the new network society.
Why Toshiba QKD
We started research into quantum cryptography in 1999 at the Cambridge Research Laboratory of Toshiba Research Europe Limited. Since then we have demonstrated a number of notable world firsts. We were the first to announce quantum key distribution over 100 km of fiber in 2003 and the first with a continuous key rate exceeding 1 Mbit/second in 2010 and 10 Mbit/second in 2017.
Products and Services
Hardware Products
Toshiba offers two advanced QKD system variants to meet a wide range of network requirements:
Multiplexed QKD System;
Designed to operate alongside conventional data on the same optical fiber, this solution enables secure key distribution without the need for dedicated infrastructure, optimizing both cost and efficiency.
Long-Distance QKD System;
Engineered for high key rate and extended transmission range, this system is ideal for high-performance, long-haul quantum networks.
Software Products
Toshiba’s Quantum Key Management System (Q-KMS) is a robust software platform built to scale QKD networks with ease and efficiency.
Q-KMS enables secure key routing between any connected locations across the QKD infrastructure, making large-scale, quantum-safe communication practical and efficient.
It supports key delivery through standard APIs, including ETSI (European Telecommunications Standards Institute) and SKIP (Secure Key Integration Protocol), to ensure seamless integration with existing network environments.
Professional Services
Toshiba offers comprehensive maintenance and support services for both hardware and software solutions.
Our expertise also includes QKD network design and construction consulting. We provide on-site installation and training to ensure seamless implementation and long- term performance.

Use Cases
Securing the high speed transfer of large scale sensitive genome data between two remote sites
Genome researchers have always been concerned about the security of transferring large-scale genome sequence data. Indeed, there have been examples where they have physically transported hard disks in locked security boxes, which is clearly problematic in terms of cost and time.
