The Cisco Universal Quantum Switch is designed to route quantum information between systems while preserving it, with a Cisco-patented conversion engine that translates between all encoding and entanglement modalities at input and output.

In proof-of-concept experiments, the switch preserved quantum information with less than 4% degradation in encoding and entanglement fidelity. The complete findings are expected to be published in an upcoming research paper on ArXiv.

Cisco Quantum Labs has unveiled a universal quantum switch that routes quantum information via single photons through standard optical fiber without measuring or destroying the quantum state. The device is fully reconfigurable and non-blocking, enabling multiple quantum computers from different vendors to be networked together into a scalable fabric — analogous to how thousands of GPUs are clustered for AI workloads. The broader implication highlighted is that once quantum computing matures, current asymmetric encryption standards like RSA will be rendered obsolete.
