Joseph Salfi (jsalfi-at-ece.ubc.ca)
About Dr. Salfi: I am an experimental quantum physicist and electrical engineer. My research interests centre on the physical properties of spin and superconductor based quantum devices.
I primarily affilaited with the Department of Electrical and Computer Engineering at the University of British Columbia. I am also currently a principal investigator of the Stewart Blusson Quantum Matter Institute, and an affiliate member of the Department of Physics and Astronomy, at the University of British Columbia.
More information on research interests can be found here.
I am distinguished in my research field for the theoretical predictions and first experimental demonstration of ultra-long-lived quantum bits hole valence band hole spin, with strong intrinsic spin-orbit coupling [Nature Materials 2021, PhysOrg Coverage, Physical Review Letters 2016,US patent US9691033B2]. Spin-orbit qubits are advantageous for building large-scale quantum information technologies. I also accomplished the first proof-of-principal experimental demonstration of analog quantum simulation of the Fermi-Hubbard model with spins in silicon. The Fermi-Hubbard model is the quantum mechanical model behind some of the most puzzling phenomena in condensed matter physics [Nature Communications 2016 and Phys.org popular coverage]. My research is industrially relevant because it is based on silicon materials that underpin classical computer technologies .
