SUMMARY:Quantum BC Seminar Series - Dr. Malcolm Kennett
DESCRIPTION:Quantum BC Seminar Series Tuesday\, October 14\, 2025 at 2pm BC Time \nSpeaker: Dr. Malcolm Kennett from Simon Fraser University \nJoin on Zoom: https://ubc.zoom.us/j/69443327772?pwd=TGhhTXFIQ3ZiUmNrN0pUa3FObTNydz09 \nMeeting ID: 694 4332 7772 Passcode: 996727 \nJoin in Person At SFU Burnaby: SCP 8445.2 \nSeminar Title: Out of equilibrium dynamics and information spreading in the Bose Hubbard model \n  \nSeminar Abstract: The Bose-Hubbard model (BHM) is the simplest model of interacting bosons on a lattice and  can be realized with ultra-cold \natoms in an optical lattice.   As the ratio of interactions to hopping are tuned in the model there is a quantum phase transition \nbetween a superfluid and an insulating phase that has been observed experimentally.  Out of equilibrium phenomena in the \nBHM\, such as the spreading of correlations\, thermalization and many-body localization have attracted considerable interest in recent years.   While dynamics in one dimension can be solved essentially exactly\, approximate methods are required in higher dimensions.  This has opened up the suggestion of using cold bosons in an optical lattice as a quantum simulator. We have developed a strong coupling approach that allows us to access out of equilibrium phenomena in dimensions higher than one.  I will survey results that we have obtained with this method which include: i) investigating the spreading of correlations in one\, two and three dimensions and comparing to experimental results; ii) studying the effect of disorder on the BHM phase diagram and its implications for experimental claims of many body localization; and iii) \napplying a machine learning approach to obtain quantitative improvements to our calculations of single particle correlations that may be generalizable to out of equilibrium dynamics in other quantum systems. \n  \nShort biography: Malcolm Kennett obtained his B.Sc and M.Sc degrees in Astrophysics from the University of Sydney\, followed by a Ph.D in Condensed Matter Theory at Princeton University.  He was a postdoc in the Theory of Condensed Matter Group at the University of Cambridge before moving to SFU as a faculty member in 2005.  He currently works on out of equilibrium dynamics in strongly interacting quantum systems\, with a focus on ultra-cold atoms\, and on properties of quantum materials. \n  \n  \n  \n

SUMMARY:FABrIC Build Your Own Superconducting Quantum Device Workshop
DESCRIPTION:A growing number of Canadian companies (i.e.\, Qubic\, Xanadu\, Nord Quantique\, DWave\, Anyon Systems) are now building quantum computers based on superconducting technology\, requiring a combination of components such as quantum bits\, couplers\, and control and readout lines in a single chip. A local start-up like Red Blue Quantum\, based in Waterloo\, is providing qubit and superconducting circuit fabrication services to the ecosystem\, and its founders have been involved as instructors\, participants\, or advisers in this event in previous editions. At least one company\, Qubic Technologies\, is leveraging the technology for sensing\, transmitting and receiving applications\, making its mark in the field. All these require an understanding of the hardware they rely upon. A small design or fabrication error may lead to a complete failure of a quantum-computer chip or sensor\, wasting development time and resources. Therefore\, the talent developing these components must master fundamental concepts of physics (quantum mechanics and superconductivity) and state-of-the-art design and simulation tools and techniques to fabricate working devices. Additionally\, earlier established companies\, including Keysight\, Siemens\, and Cadence\, are opening quantum divisions and providing supporting elements such as tools and instrumentations to the quantum ecosystem. And they can use events such as this one to scope out the requirements for their products. Many other companies or organizations focusing on quantum computing can benefit from a better understanding of the issues faced by the hardware in reproducing the quantum states upon which their applications and algorithms are built. \n\n\n\n\nTo train highly qualified personnel to develop state-of-the-art quantum computers\, CMC Microsystems is joining forces with the Institute for Quantum Computing/University of Waterloo\, Institut quantique\, University of Victoria\, and University of British Columbia to deliver the 5th edition of the “Build your Own Superconducting Quantum Device Workshop”. The workshop will provide a training experience for 50 participants from industry\, as well as Canadian and foreign universities\, with relevant science or engineering backgrounds. \n\n\n\n\nThe workshop will teach participants how to design\, simulate\, fabricate\, and test their superconducting circuits. It will cover the fundamentals of superconductors and Josephson junctions\, and how to design circuits such as resonators and qubits. Trainees will brainstorm device ideas with leading Canadian universities and industry researchers. They will use CMC-provided CAD tools to design\, simulate\, and submit devices for fabrication. Most trainees will test their chips at their home institution. \n\n\n\n\nDuring the workshop\, participants will have the opportunity to attend the Quantum Networking Day. Moreover\, attendees are encouraged to participate in the Superconducting Quantum Device Design Awards (See details below). Don’t miss CMC BasecampTM Build Your Own Superconducting Quantum Device workshop\, which will allow you to learn why superconducting devices are at the heart of today’s commercial quantum computers such as those of Nord Quantique\, Anyon Systems\, D-Wave\, and IBM. \n\n\n\n\nSuperconducting Quantum Device Design Awards\n\n\n\n\nParticipants are encouraged to participate in a Device Design Award (a virtual event) in March 2026. The best design ideas will be awarded* for the fabrication of their devices. \nEligibility criteria: \n\nAttend the in-person workshop.\nBe enrolled in graduate studies in Canada.\nSubmit the design layout file for evaluation during the Device Design Award.\nPresent their device ideas to a panel of experts at the Device Design Award event.\nAgree to submit a device test report 4 to 6 months after receiving the fabricated device.\n\n*A limited number of awards are available. \n\nFor More Info And To Register

SUMMARY:Quantum BC Seminar with Dr. Gregor Weihs
DESCRIPTION:Quantum BC Seminar Series Tuesday\, October 28\, 2025 at 2pm BC Time with Dr. Gregor Weihs \nJoin on Zoom: https://ubc.zoom.us/j/69443327772?pwd=TGhhTXFIQ3ZiUmNrN0pUa3FObTNydz09 \nMeeting ID: 694 4332 7772 Passcode: 996727 \nJoin in Person At SFU Burnaby: SCP 8445.2 \nSeminar Title: Quantum Science Austria & Quantum Light Sources \n  \nSeminar Abstract: \nThis presentation will have two parts. For one I would like to introduce Quantum Science Austria\, a large Cluster of Excellence funded by the Austrian Science Fund (FWF). Under its umbrella about 70 research groups at six Austrian institutions pursue cutting-edge research on three topics in fundamental quantum science: “Quantum Physics of Space\, Time and Gravity”\, “New Paradigms of Quantum Information Science”\, and “Physics of Engineered Quantum Many-Body Systems”. In addition to its research the Cluster promotes training of early-stage researchers and knowledge and technology transfer. \nThe second part of my presentation is all about quantum light sources. High-quality single photons\, entangled photon pairs and other quantum states of light are what powers optical quantum information processing and quantum communication. In our research we rely on spontaneous parametric down-conversion in crystals or waveguides and on single semiconductor quantum dots. \nRecent results include photons with unprecedented spectral purity through joint nonlinearity and pump engineering\, ultra-wide-band photon pairs from integrated nonlinear semiconductor waveguides [1]\, single photons from quantum dots with controllable photon-number coherence [2]\, and coherent control of dark states in quantum dots for advanced encoding in quantum communication [3]. \n\nThiel\, L.
