Babcock and Arqit Demonstrate Quantum-Safe Encryption for Defence Communications

Insider Brief

• Babcock and Arqit demonstrated secure transmission of scenario data between two sites at DVD 2026 using Arqit’s encryption technology.
• The demonstration transferred data from Millbrook to Babcock’s Ground Deployed Advanced Mortar System through a layered encryption network without physical inline encryptors.
• The demonstration follows an MoU between Babcock and Arqit covering potential collaboration on secure networking, systems integration, digital engineering and cryptographic technologies.

PRESS RELEASE — Babcock International Group (Babcock), the defence company, has demonstrated its systems integration expertise by securely transferring scenario data using advanced encryption technology from Arqit Quantum Inc, a global leader in quantum-safe encryption, helping safeguard sensitive information from future cyber threats.

Data was collected at one site in Millbrook at DVD 2026, encrypted by Arqit software and securely transmitted to Babcock’s Ground Deployed Advanced Mortar System (GDAMS), located at another site at the event.

It demonstrated how critical operational information could be exchanged securely in a layered encryption network between a headquarters and a deployed platform in a contested environment, enabling rapid and better-informed decision-making on the battlefield without the use of physical inline encryptors.
