Xanadu raises $100 million for photonic quantum computing

Xanadu, a start-up based in Toronto, announced US$100 million in Series C financing to advance its photonic quantum computing.

Founded in 2016, Xanadu's photonic approach to building quantum computers leverages of modern chip manufacturing facilities, the application of optical components developed by the pre-existing telecommunications industry and the use of fibre optics to network photonic chips together. The copmany also leads the development of PennyLane, an open-source software library for quantum computing and application development.

Canada's largest growth equity firm, Georgian, led the round with participation from Porsche Automobil Holding SE, Forward Ventures, Alumni Ventures, Pegasus Tech Ventures, Silicon Valley Bank, along with previous investors Bessemer Venture Partners, Capricorn, BDC Capital, and Tim Draper. To date, Xanadu has raised $250M USD, bringing the company valuation to $1B USD.

"The continued support from top-tier investors in this uncertain economic climate is a testament to the belief in our exceptional team, our photonic technology, and our ability to execute," said Xanadu founder and Chief Executive Officer, Christian Weedbrook.

"These achievements have fostered the growth of the quantum community and enabled researchers and developers globally to access the most cutting-edge computational tools to create new algorithms that will eventually solve real-world problems, such as next generation battery development, a highly strategic area for Volkswagen Group's NEW AUTO strategy," said Dr. Arne-Christian Voigt, Future Research Volkswagen AG.

Xanadu and imec target photonic qubits in silicon nitride waveguides

Xanadu, a start-up based in Toronto, announced a partnership with imec to develop photonic qubits based on ultra-low loss silicon nitride (SiN) waveguides.

imec is a leading research and innovation center in nanoelectronics and digital technologies based in Belgium. 

Xanadu is developing a unique type of quantum computer powered by photonic qubits based on squeezed states - a special type of light generated by chip-integrated silicon photonic devices. Such an approach uses particles of light to carry information through photonic chips, rather than electrons or ions used by other approaches. 

Xanadu said its photonic approach offers the benefits of scalability to one million qubits via optical networking, room temperature computation, and the natural ability to leverage fabrication R&D centers such as imec. Xanadu is using silicon nitride to enable the generation of squeezed states, which replace single photons as the basic resource for synthesizing qubits. Squeezed states are deterministically generated, and can be used to distill error-resistant qubits called 'GKP states'. When multiplexed and implemented in Xanadu's architecture, these offer a more promising path to fault-tolerant quantum computing. 

Amin Abbasi, business development manager at imec: "We are pleased to see that imec's wafer-scale low loss SiN photonics platform, initially developed for communication, is finding its way towards other advanced applications, like quantum computing. We look forward to working with Xanadu to drive further development of this platform for their particular needs."

"We are pleased to partner with Xanadu, one of the most exciting companies working in the quantum computing space." said Philippe Helin, specialty components program manager at imec. "Xanadu's mission to build photonic quantum computers matches perfectly with imec's track record of and commitment to pushing the leading edge of integrated technologies," adds Haris Osman, VP R&D and head of department.

"One of the most critical challenges in building a photonic quantum computer is finding the right fabrication partner that can simultaneously deliver cutting-edge process development and volume production of high performing photonic chips," said Zachary Vernon, who heads up Xanadu's Hardware team. "Imec is one of the few semiconductor R&D centers that does advanced technology R&D on advanced 200mm and 300mm lines, as well as volume manufacturing on their 200mm line, capable of delivering up to a thousand wafers per year per customer on a few platforms including ultralow-loss photonic platforms. The seamless transfer offered by imec of new processes to production is especially critical for rapid scaling of our technology."
