Demonstration of the Two-Fluxonium Cross-Resonance Gate
Ebru Dogan, Dario Rosenstock, Loïck Le Guevel +7
The superconducting fluxonium qubit has a great potential for high-fidelity quantum gates with its long coherence times and strong anharmonicity at the half flux quantum sweet spot…
Millisecond coherence in a superconducting qubit
Aaron Somoroff, Quentin Ficheux, Raymond A. Mencia +3
Increasing the degree of control over physical qubits is a crucial component of quantum computing research. We report a superconducting qubit of fluxonium type with the Ramsey cohe…
The superconducting quasicharge qubit
Ivan V. Pechenezhskiy, Raymond A. Mencia, Long B. Nguyen +2
The non-dissipative non-linearity of a Josephson junction converts macroscopic superconducting circuits into artificial atoms, enabling some of the best controlled quantum bits (qu…
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…
