EE Devices Seminar - Machiel Blok, Univ of Rochester
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.
