Quantum computing has the potential to solve problems beyond the capabilities of conventional supercomputers. It could revolutionise the advancement of several fields, including biochemistry, finance, logistics, and artificial intelligence. Two photonic quantum computers have reached the milestone of quantum advantage (Jian-Wei Pan’s group at the University of Science and Technology of China, and Xanadu in Toronto, Canada). Building a quantum computer using integrated silicon photonics provides the advantage of a scalable platform based on silicon manufacturing.
The NSERC CREATE Quantum BC program and CMC Microsystems bring to you a workshop on the design, fabrication, and testing of quantum silicon photonic circuits used in quantum computer hardware. We invite you to join the workshop taking place in person at The University of British Columbia from February 20 to 24, 2023.
The workshop will teach participants how to design, simulate, fabricate, and test their own quantum silicon photonic circuits. Students will gain an understanding of the fundamentals of quantum optics and how photonics can be used for quantum computing, and about the types of problems that can be solved on photonic-based processors, particularly with Xanadu’s cloud-accessed quantum processor. During the workshop, students will practice creating a design and layout of a quantum silicon photonic circuit. Students will brainstorm and pitch their circuit idea to researchers at leading universities and industry. After the workshop, students will have several months to complete their design, and submit their circuits for fabrication by a foundry (Applied Nanotools) facilitated by CMC. Participants will test their chips using equipment at their own university, or by their own arrangements such as via a collaboration with the workshop instructors and/or visits with their facilities.
The focus of the workshop is on devices and circuits that can be fabricated in the chosen silicon photonics processes. The processes are based on silicon wafers with a choice of either Si or SiN waveguides surrounded by silicon oxide cladding (SiNOI or SOI), metal heaters for phase shifters, and a deep trench etch for edge coupling or photonic wire bond packaging to optical fibres.
Organized by
Important Notes:
- The representing organizations of the interested participants will have to sign a 3-way Non-Disclosure Agreement (NDA) with CMC Microsystems and Applied Nanotools Inc. This will provide presenters and participants with an opportunity to delve deeper into topics of interest in the course of the workshop. For access and more information regarding this document, please contact Jennifer Draper. The document submission deadline is February 6, 2023.
- In addition to the 3-way NDA, each participant is required to sign an Access to Intellectual Property NDA. This individual-based NDA is set in place to protect each designer’s intellectual rights from potential exposure to other participants during the design competition review sessions and other relevant group activities. For access and more information regarding this document please contact Sarah J. Neville. The submission deadline is February 6, 2023.
