Observation of classical-quantum crossover of 1/f flux noise and its paramagnetic temperature dependence
C. M. Quintana, Yu Chen, D. Sank +25
By analyzing the dissipative dynamics of a tunable gap flux qubit, we extract both sides of its two-sided environmental flux noise spectral density over a range of frequencies arou…

Tunable inductive coupling of superconducting qubits in the strongly nonlinear regime
Dvir Kafri, Chris Quintana, Yu Chen +3
For a variety of superconducting qubits, tunable interactions are achieved through mutual inductive coupling to a coupler circuit containing a nonlinear Josephson element. In this…
