New Performance Benchmarks Achieved
By using a specialized fabrication technique, the partnership has produced new photonic chips with performance never seen before. Key accomplishments include:
- Below 2 dB/m for waveguide losses in Thin Film Lithium Niobate.
- Roughly 20 milli-decibel (mdB) in losses from electro-optic switches.
For photonic quantum computing applications, these numbers reflect some of the lowest loss values ever documented for an electro-optic switch. A semiconductor fabrication plant with a high volume produced this remarkable outcome. Future utility-scale quantum computers will have high demands, and the production of wafers in the quantities needed for commercial photonic quantum computing is essential.
Accelerating the Path to Utility-Scale Quantum Computers
The roadmap that Xanadu has developed for utility-scale quantum computers is greatly aided by these developments. These new photonic chips’ unparalleled capability “sets a new benchmark for performance in the industry and brings us closer to delivering utility-scale photonic quantum computers,” said Zachary Vernon, CTO of Hardware at Xanadu. Additionally, he stated that the performance attained by these new photonic chips facilitates the creation of photonic quantum computers in the future.
The groundwork for Xanadu’s recent display of Aurora, the first fiber-networked photonic quantum computer in history, was laid by this most recent development. HyperLight’s cutting-edge TFLN Chiplet technology was utilized by Aurora, which demonstrated the scalability and networkability of Xanadu’s architecture for a photonic quantum computer. For upcoming generations of photonic quantum computers, the recently created, more efficient circuits are crucial. Achieving Xanadu’s hardware roadmap has been made possible by the extended partnership with HyperLight.
