Xanadu will leverage the advanced 300mm GF Fotonix™ silicon photonics platform for mass manufacturing of key components needed for quantum error correction and fault tolerance

TORONTO, March 7, 2022 /CNW/ – Xanadu today announced a collaboration with GlobalFoundries® (GF®) to take the first steps towards the large-scale fabrication of photonic chips for universal and fault-tolerant quantum computers. Leveraging the sophistication and rich functionality offered by GF Fotonix™, Xanadu now designs integrated photonic devices, used to implement quantum error correction, for 300mm wafer fabrication.

Error correction is an essential procedure for achieving fault tolerance, which is necessary to fulfill the promise of quantum computing to solve computational problems previously thought to be unsolvable. This exponential increase in computing power will transform a wide range of industries, driving major advances in everything from cancer therapies to high-performance battery materials.

Unlike other approaches, Xanadu’s architecture implements error correction on silicon photonic chips that operate entirely at room temperature, using photodetector technology borrowed from the optical telecommunications and LIDAR industries. This makes Xanadu’s approach uniquely compatible with existing silicon photonic fabrication capabilities, such as those developed and perfected by GF.

GF Fotonix is ​​a monolithic platform, the industry’s first to combine its 300mm differentiated photonics capabilities and 300GHz class RF-CMOS on a silicon wafer, delivering the best large-scale performance.

“GF Fotonix moves data at the speed of light using our advanced processes that combine the advantages of affordable, efficient and proven CMOS manufacturing with the optical capabilities of silicon photonics,” said Anthony You, Vice President of IT and Cable Infrastructure at GF. “We’re excited to partner with Xanadu to use GF Fotonix’s capabilities for error correction, which is critical to advancing quantum computing.”

The first fully functional devices designed by Xanadu and manufactured by GF will be ready by the end of 2023.

“Many chips, working in parallel and networked, are needed to process the large number of qubits involved in fault-tolerant quantum computing algorithms,” said Zachary Vernon, head of hardware at Xanadu. “Leveraging an existing advanced 300mm platform like GF Fotonix gives us a huge advantage in the race to deliver a useful, error-corrected quantum computer.”
