The high-coherence fluxonium qubit
Long B. Nguyen, Yen-Hsiang Lin, Aaron Somoroff +3
We report superconducting fluxonium qubits with coherence times largely limited by energy relaxation and reproducibly satisfying T2 > 100 microseconds (T2 > 300 microseconds in one…
Superstrong coupling in circuit quantum electrodynamics
Roman Kuzmin, Nitish Mehta, Nicholas Grabon +2
Vacuum fluctuations fundamentally affect an atom by inducing a finite excited state lifetime along with a Lamb shift of its transition frequency. Here we report the reverse effect:…
Quantum electrodynamics of a superconductor-insulator phase transition
Roman Kuzmin, Raymond Mencia, Nicholas Grabon +3
A chain of Josephson junctions implements one of the simplest many-body models undergoing a superconductor-insulator (SI) quantum phase transition between states with zero and infi…
