In a groundbreaking announcement, Photonic Inc, a quantum startup based in Vancouver, has unveiled its new quantum architecture after years of stealth development. The company has not only closed its latest $100M funding round but has also gained Microsoft Corporation as a significant new investor. The collaboration between Photonic Inc and Microsoft aims to bring this revolutionary technology to Microsoft Quantum Azure Elements and explore its potential as a quantum networking solution. These developments mark a pivotal moment in the quantum sector this year.
The existing landscape of quantum research is fragmented, with various groups focusing on different aspects of quantum technologies. However, Photonic Inc’s architecture has the potential to bridge the gap between these disparate fields. By leveraging the T center, a manufactured color center defect in silicon, Photonic Inc has achieved several advantages:
– The use of 28Si promises long qubit lifetimes, even at relatively low temperatures.
– The T centers operate at a wavelength compatible with the telecoms O-band, facilitating seamless integration with existing networking infrastructure.
– The architecture benefits from advanced nanofabrication technologies and components through silicon-on-insulator (SOI).
– The incorporation of waveguides and optical cavities enhances the spin-photon interface.
– The scalable fabrication process allows for the creation of compact arrays with thousands of T centers.
What sets Photonic Inc’s architecture apart is its departure from conventional methods of forming 2Q gates and coupling computational qubits with communication qubits. Instead, Photonic Inc utilizes a flexibly switched optical network and implements 2Q gates via Bell pair measurement. This approach enables high modular scalability, all-to-all connectivity, and the potential use of high-rate Q LDPC codes for error correction.
While Photonic Inc has not disclosed detailed progress publicly, founder Dr. Stephanie Simmons anticipates that the company will be the first to offer a scalable, distributed, and fault-tolerant quantum computing solution within five years. As part of the investment round, GQI conducted technical due diligence and found Simmons’ statement to be ambitious but plausible. However, several key challenges remain, including achieving high rates of entanglement generation, ensuring high component yields, developing a dynamic optical switching system, identifying specific Q LDPC architectures, and securing a source of silicon-28 for manufacturing.
If these challenges can be overcome, Photonic Inc’s architecture holds the promise of scalable fault-tolerant quantum computing (SFTQ). GQI believes this architecture could lead to the development of a cryptographically relevant quantum computer and urges those considering migration to quantum-safe cryptography to reassess their plans. Additionally, the architecture shows great potential for quantum simulation applications in material science, quantum chemistry, and beyond.
