Photonic Demonstrates Distributed Entanglement Between Modules, Marking Significant Milestone Toward Scalable Quantum Computing and Networking

Technology / Press Release June 1, 2024

VANCOUVER, British Columbia, May 30, 2024 -- Photonic Inc., a leader in distributed quantum computing in silicon, today 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. In this way, Photonic’s architecture provides a unique solution to one of the primary challenges on the road to large-scale quantum adoption—scalable entanglement distribution—and literally goes “outside the box” to open avenues for transformative applications in fields such as materials science and drug discovery.

“The crucial role that entanglement distribution will play in unlocking the commercial promise of quantum computing cannot be overstated. Large-scale quantum algorithms running across multiple quantum computers require enormous amounts of distributed entanglement to work well,” said Dr. Stephanie Simmons, Founder and Chief Quantum Officer at Photonic. “These demonstrations highlight the promise of our distinctive architectural approach to solve the challenge of scaling beyond single nodes. While there is still much work ahead, it’s important to acknowledge the pivotal role that entanglement distribution must play in shaping quantum system designs.”

“Last November, we announced a strategic collaboration with Photonic to co-innovate on quantum technologies to accelerate scientific discovery. These recent developments showcase a fundamental capability: entanglement distribution over long distances. With these advancements, we’re progressing toward the next stages of networked quantum computing.” Krysta Svore, Distinguished Engineer and Vice President of Advanced Quantum Development at Microsoft.

Photonic’s approach is based on optically-linked silicon spin qubits with a native telecom networking interface, meaning that it can integrate with the infrastructure, platforms, and scale of today’s global telecommunications networks, including the Microsoft Azure cloud. Three demonstrations, culminating in the teleported CNOT gate sequence, established and consumed distributed quantum entanglement—entanglement between qubits not adjacent to one another or even in the same cryostat.
