SUMMARY:Quantum BC Seminar Series -  Rogério de Sousa
DESCRIPTION:Join us on Tuesday\, September 12 at 2pm for a seminar by Dr. Rogério de Sousa from the University of Victoria. \nSept.2023.Seminar.RdeSousa \nTitle: Noise in Chip-Based Quantum Computers \nhttps://ubc.zoom.us/j/69443327772?pwd=TGhhTXFIQ3ZiUmNrN0pUa3FObTNydz09 \nMeeting ID: 694 4332 7772 \nPasscode: 996727 \nAbstract: Quantum computers are now available in several different chip-based technologies\, but their quantum evolution is noisy\, hindering demonstrations of quantum advantage over conventional computers. In this talk I will discuss the microscopic origin of electric and magnetic noise in the solid-state environment surrounding qubits. While some noise sources are intrinsic to the surfaces and interfaces within the chip [1]\, others are extrinsic in that they originate from impurities and defects within the materials forming the qubit [2\, 3]. I will describe strategies to reduce the impact of noise on quantum computers using both hardware [4] and software [5] approaches. \n[1] I.

He was a postdoctoral fellow at the Departments of Chemistry and Physics at University of California\, Berkeley\, and moved to Canada in 2007 to join the Dept. of Physics and Astronomy at University of Victoria. His research group focuses on how to design quantum computing hardware and software with less noise.  They are implementing quantum algorithms in the current generation of noisy intermediate-scale quantum devices\, and developing methods to benchmark as well as mitigate the impact of noise in them. \nProf. de Sousa is also interested in making quantum theory more accessible to people with different expertise. At UVic he teaches the course “Introductory Quantum Computing”\, targeted at second-year science and engineering students with no previous exposure to quantum theory.
