SUMMARY:QBC Seminar Series - Stephanie Simmons
DESCRIPTION:The Quantum BC Seminar Series is a monthly talk given by faculty in BC on various topics related to quantum computing. The talks happen on the second Tuesday of each month at 2pm. \nPlease join us for our first seminar with Dr. Stephanie Simmons on Tuesday\, March 14\, 2023 at 2pm. Dr. Simmons will speak about Silicon Colour Centres. \nSilicon Colour Centres:  \nThe future global quantum internet will require high-performance matter-photon interfaces. The highly demanding technological requirements indicate that the matter-photon interfaces currently under study all have potentially unworkable drawbacks\, and there is a global race underway to identify the best possible new alternative. For overwhelming commercial and quantum reasons\, silicon is the best possible host for such an interface. Silicon is not only the most developed integrated photonics and electronics platform by far\, isotopically purified silicon-28 has also set records for quantum lifetimes at both cryogenic and room temperatures [1]. Despite this\, the vast majority of research into photon-spin interfaces has notably focused on visible-wavelength colour centres in other materials. \nIn this talk I will introduce a variety of silicon colour centres and discuss their properties in isotopically purified silicon-28. Some of these centres have zero-phonon optical transitions in the telecommunications bands [2]\, some have long-lived spins in their ground states [3]\, and some\, including the newly rediscovered T centre\, have both [4] and can be integrated into silicon photonics chips at scale [5]. \n[1] K.

Chartrand et al. Nature 607:266 (2022). \n\nBiography: \nDr Stephanie Simmons is an Associate Professor\, Canada Research Chair\, CIFAR Quantum Information Science Fellow\, Co-chair of the National Quantum Strategy Advisory Council\, based out of the Department of Physics at Simon Fraser University (SFU)\, and is the Founder and Chief Quantum Officer of Photonic Inc. Her work on silicon quantum technologies was awarded a Physics World Top Ten Breakthrough of the Year of 2013 and again in 2015\, and she is one of only 5 individuals to have ever won this award twice. She was named one of Canada’s Top 40 Under 40 for 2020\, and her work has been covered by the New York Times\, CBC\, BBC\, Scientific American\, the New Scientist\, and many others. \n\nTuesday\, March 14 at 2pm: \nJoin in Person (Dr. Simmons will be joining virtually and the talk will be broadcast with refreshments): \nSFU Burnaby\, WAC Bennett Library Room 7200 \n  \nJoin on Zoom: \nhttps://ubc.zoom.us/j/69443327772?pwd=TGhhTXFIQ3ZiUmNrN0pUa3FObTNydz09 \nMeeting ID: 694 4332 7772 \nPasscode: 996727
