Quantum Computing Inc. (QCi) plans its first public demonstration of an integrated quantum security platform at ECOC Exhibition 2026 in Málaga, Spain, from September 21 through September 23. The system combines high-dimensional quantum key distribution, Quantum Identity Authentication, encryption and key management in a telecom-compatible architecture. QCi says its technology uses direct entanglement verification, quantum zero-knowledge proofs and room-temperature equipment to reduce reliance on classical authentication methods. The company will demonstrate time-frequency and polarization-based quantum communications at Booth 1436 at FYCMA, while also displaying photonics components and quantum testing equipment. QUBT shares traded at $8.35, down 1.07%, after earlier gains faded.
