Toshiba Quantum Technology

Securing our
quantum future

At Toshiba, we’re committed to delivering world-leading technology that protects the private information of citizens and organisations.

As quantum computing becomes more widely available, the volume and severity of cyber attacks will put sensitive data under threat like never before. Only quantum-secure solutions will be able to withstand decryption from quantum computers, which will have the power to bypass current encryption methods in minutes.

Our quantum cyber security solutions, based on decades of scientific research, apply the fundamental laws of quantum physics to deliver provably secure network communications that will remain resilient even in the age of quantum computing.

We’re Quantum
Security Pioneers

Toshiba has been at the forefront of quantum computing technology since 1999. Our solutions underpin the world’s first quantum-secured metro network, and we’ve created a quantum-secure communication platform that makes existing data-carrying networks safe from attack by quantum computers, without any compromise to performance.

We’ve achieved a series of world firsts in quantum technology deployment, developing quantum-secure and future-proof network communications infrastructures that can protect data from any threat – even those posed by quantum computers.

Our Quantum Technology team in Singapore is thrilled to be participating in Asia Tech x Singapore – TechXLR8's Quantum Technology Summit, Asia’s flagship tech event which brings together quantum industry experts to explore the development of digitally secured communications across industries.
As part of the event, we’ve had the privilege of collaborating with our strategic partner for Quantum Key Distribution (QKD) in Southeast Asia, SpeQtral, to showcase the immense potential of quantum technology and how we’re working together to secure data online.
Our Chief Evangelist of the QKD Business Development Office, Mr. Katsuro Ejima, and the Co-Founder, and CEO of SpeQtral, Mr. Chune Yang Lum Yang, delivered an insightful presentation on "Empowering Southeast Asia's Digital Future with Quantum-Secure Communications Networks." This showcased how QKD integrates into today's secure communication networks, the future of data protection in the era of quantum computing, and how this is made possible through the partnership between Toshiba and SpeQtral.
