Quantum Computing Inc. to Showcase Quantum Secure Communications Beyond Quantum Key Distribution at ECOC 2026

• First-time live demonstration combines quantum encryption and authentication on a single platform, alongside quantum key distribution and advanced instrumentation for secure optical communications

HOBOKEN, N.J., Sept. 18, 2026 /PRNewswire/ -- Quantum Computing Inc. ("QCi" or the "Company") (Nasdaq: QUBT), a vertically integrated quantum company pioneering photonics and semiconductor manufacturing, today announced it will showcase, for the first time, an integrated quantum security platform that brings encryption and authentication together in a single solution, at the ECOC Exhibition 2026, September 21–23 at FYCMA in Málaga, Spain. At Booth #1436, QCi will demonstrate live quantum communication solutions leveraging time-frequency and polarization-based approaches, highlighting how quantum technologies are moving from research and development toward practical solutions for securing the communications infrastructure of the future.

As organizations prepare for the post-quantum era, the challenge is no longer understanding the value of quantum-secure communications, but overcoming the barriers that have limited deployment. Traditional QKD systems often face challenges associated with scalability, operational complexity, infrastructure cost, and dependence on classical authentication methods. As a result, many quantum communication technologies have remained confined to specialized research environments.
