Universal Jaynes-Cummings Control of an Oscillator
Jordan Huang, Ethan Kasaba, Thomas J. DiNapoli +2
The Jaynes-Cummings (JC) interaction-the coherent exchange of excitations between a two-level system and a harmonic oscillator-is one of the fundamental interactions of quantum opt…
Universal monitored dynamics in multimode bosonic systems
Shivam Patel, Catherine McCarthy, Ahana Chakraborty +5
We propose a route to study monitored many-body dynamics in multimode bosonic systems using circuit quantum electrodynamics. In this experimental setting, we construct several boso…
Fast Sideband Control of a Weakly Coupled Multimode Bosonic Memory
Jordan Huang, Thomas J. DiNapoli, Gavin Rockwood +9
Circuit quantum electrodynamics (cQED) with superconducting cavities coupled to nonlinear circuits like transmons offers a promising platform for hardware-efficient quantum informa…
Suppression of quasiparticle poisoning in transmon qubits by gap engineering
Plamen Kamenov, Thomas DiNapoli, Michael Gershenson +1
The performance of various superconducting devices operating at ultra-low temperatures is impaired by the presence of non-equilibrium quasiparticles. Inelastic quasiparticle (QP) t…
