High Coherence Superconducting Artificial Atom

Long Nguyen

University of Maryland

Long is a graduate student in the Superconducting Circuit group led by Vladimir Manucharyan at the University of Maryland, College Park. He has been working on fluxonium qubit since 2014, being one of the lab's founding members. Long has been working on investigating the effect of environment on qubit's coherence, engineering qubits' coupling to cavity and between themselves, as well as improving the shelving readout scheme.


Fluxonium [1] is a versatile multilevel superconducting artificial atom. It consists of a capacitor, a superinductor [2], and a Josephson junction in parallel. The three elements can be tuned to reach different regimes with... [ view full abstract ]
