Arqit joins Tomorrow Street portfolio with quantum security

Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW) (“Arqit”), global leader in PQC migration tooling and quantum-safe encryption, has been selected to join the Tomorrow Street portfolio as a Scaleup Partner. Arqit is the first quantum security company to join the portfolio. Tomorrow Street is a joint venture between Vodafone and Luxembourg's technology incubator Technoport.

This milestone follows Arqit’s participation in Tomorrow Street’s 2025 Scaleup X programme, where it engaged with technology stakeholders and demonstrated the relevance of its solutions in addressing emerging cybersecurity challenges across Tomorrow Street’s ecosystem.

As part of the portfolio, Arqit joins a group of technology companies working across areas such as data, security, and digital infrastructure. The addition reflects growing demand for solutions that can support organisations in preparing for the transition to post-quantum security environments.

Scaling capabilities

Through Tomorrow Street’s ecosystem, Arqit will have the opportunity to develop and scale its capabilities further, supporting organisations in understanding cryptographic risk, identifying vulnerabilities, and planning for quantum-resilient security strategies. Customers can also benefit from a clear path to securing data and achieving data sovereignty in the post-quantum era utilizing Arqit’s NetworkSecure™. 

Arqit brings strong expertise in an area that is becoming increasingly important for organizations as they prepare for the future of security.

Andy Leaver, CEO at Arqit, says: "We’re proud to be the first quantum security company to join the Tomorrow Street Scaleup Partners portfolio. This has been driven by growing customer demand due to the acceleration of PQC migration timelines. Arqit’s selection is a strong endorsement of the comprehensive, end-to-end solution we provide to help organizations meet these fast-evolving requirements."
