Arqit Quantum Inc. (NASDAQ: ARQQ, ARQQW) has been selected as a partner in Tomorrow Street's portfolio, marking the first quantum security company to join the technology incubator program.

Tomorrow Street, a joint venture between Vodafone Group and Luxembourg's national technology incubator Technoport, added Arqit following the company's participation in the 2025 Scaleup X programme. The selection reflects growing demand for post-quantum security solutions as organizations prepare for transitions in cybersecurity infrastructure.

Through the partnership, Arqit will work within Tomorrow Street's ecosystem to develop capabilities that help organizations identify cryptographic vulnerabilities and plan quantum-resilient security strategies. The company's NetworkSecure™ product aims to secure data in the post-quantum era.

"Arqit brings strong expertise in an area that is becoming increasingly important for organizations as they prepare for the future of security," said Sara Robles Moreno, CEO at Tomorrow Street.

Arqit CEO Andy Leaver stated the selection was "driven by growing customer demand due to the acceleration of PQC migration timelines."

Arqit specializes in post-quantum cryptography migration tools and quantum-safe encryption software. The company's products include Encryption Intelligence, which detects cryptographic exposure and identifies vulnerabilities, and NetworkSecure™, which protects data in transit using post-quantum cryptography.

Tomorrow Street operates as an innovation center based at Vodafone Procure & Connect, supporting technology companies across data, security, and digital infrastructure sectors. The program aims to scale technology solutions across Vodafone's global ecosystem.
