Multi-level quantum information processing with Superconducting Circuits
Seminar Series with Machiel Blok

Speaker: Machiel Blok
Host: Zlatko Minev, PhD.

Abstract:
Encoding quantum information in the higher energy levels of the transmon circuit provides a resource efficient way to control large Hilbert spaces and to execute quantum algorithms at reduced circuit complexity. In this talk, I will discuss our recent realization of a ‘qutrit quantum processor’ that manipulates quantum information in three-level systems (qutrits). At UC Berkeley, we used this device to verify the scrambling of quantum information using teleportation and benchmark its gate fidelity using a qutrit randomized benchmarking protocol. Finally, I will discuss our ongoing work at the University of Rochester where we are exploring new qutrit gates and the encodings beyond three-level systems towards a genuine qudit processor.

Bio:
Machiel Blok received his PhD in physics from Delft University of Technology/QuTech (The Netherlands) where he worked with Prof. Ronald Hanson on defect centers in diamond with a focus on quantum measurement, real-time feedback and remote entanglement. During his postdoc at UC Berkeley, in the group of Prof. Irfan Siddiqi, he developed a qutrit quantum processor in superconducting circuits. In 2020 he joined the faculty of Physics and Astronomy Department of University of Rochester as an Assistant professor, where he started a superconducting circuits lab as the inaugural Levinson/Shapiro Faculty Scholar.
