We have demonstrated coherent dynamics of a coupled superconducting two-level plus …

… superconducting transmon qubits with coherence times up to ∼60 μs, significantly improved
over those obtained with lift-off aluminum. The remaining limits to the observed coherence …

… that an array of strongly coupled qubits can display coherent collective quantum oscillations.
We have considered a particular example of an array of superconducting qubits (rf SQUIDs) …

… We demonstrate that high qubit coherence (T 1 , T 2,echo > 20 μs) is maintained in a flip-chip
geometry in the presence of galvanic, capacitive, and inductive coupling between the chips…

… We report coherence measurements of a superconducting qubit with a nonlinear dispersive
readout. Our approach involves coupling the “quantronium” qubit1 to the Josephson …

… rates of these TLS and observe the coherent coupling between an individual TLS and a
transmon qubit. Finally, we find evidence that the qubit’s frequency stability produces a 0.8 ms …

… coherence of coupled flux qubits in the context of quantum annealing. In particular, we
investigate the effect of flux noise in the coupler loop on qubit coherence. … superconducting qubits …

… superconducting coherence length. Furthermore, we show that when two double-dot singlet-triplet
qubits are tunnel coupled to a superconductor … in coupling superconducting qubits via …
