Photonic Demonstrates Distributed Entanglement Between Modules — Significant Step Toward Scalable Quantum Computing And Networking

Photonic Inc., a leader in distributed quantum computing in silicon, announced a significant milestone on the path to commercially relevant quantum systems. While many existing quantum architectures achieve entanglement within modules, Photonic has demonstrated entanglement between modules. This architecture provides a unique solution to the primary challenge of scalable entanglement distribution, which is crucial for large-scale quantum computing. Dr. Stephanie Simmons, Founder and Chief Quantum Officer at Photonic, emphasized the importance of entanglement distribution in unlocking the commercial promise of quantum computing. Photonic’s approach, based on optically-linked silicon spin qubits with a native telecom networking interface, integrates with today's global telecommunications networks. Three demonstrations, culminating in the teleported CNOT gate sequence, established and consumed distributed quantum entanglement. This advancement is significant for applications in fields such as materials science and drug discovery. Photonic’s technology sets a new bar for quantum roadmaps, aiming for 200kHz distributed entanglement with 99.8% fidelity, which would enable a wide variety of applications.
