R. G. Herb Condensed Matter Seminar
Suppression of energy relaxation in a superconducting qubit by the spectrum engineering
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: Vladimir Manucharyan, University of Maryland
Abstract: We have designed a superconducting circuit around the fluxonium artificial atom such that it has transitions with both very large and very small transition dipoles. A small dipole decouples the corresponding transition from conventional dissipation sources (e.g. dielectric loss) while the large dipole transitions couple the weak one to a microwave cavity thereby allowing to read out its quantum state. By tuning the circuit parameters with a magnetic flux, we have tuned the frequencies and dipole moments of the transitions and achieved T1 > 0.5 ms. In this talk we will discuss how the multi-level spectrum of the fluxonium artificial atom can be utilized for quantum information processing in analogy with atomic clocks.
