Probing flux and charge noise with macroscopic resonant tunneling
Alexander M. Whiticar, Anatoly Y. Smirnov, Trevor Lanting +8
We report on measurements of flux and charge noise in an rf-SQUID flux qubit using macroscopic resonant tunneling (MRT). We measure rates of incoherent tunneling from the lowest en…
Multilevel resonant tunneling in the presence of flux and charge noise
Anatoly Y. Smirnov, Alexander Whiticar, Mohammad H. Amin
Macroscopic resonant tunneling (MRT) in flux qubits is an important experimental tool for extracting information about noise produced by a qubit's surroundings. Here we present a d…
Signatures of a topological phase transition in a planar Josephson junction
A. Banerjee, O. Lesser, M. A. Rahman +12
A growing body of work suggests that planar Josephson junctions fabricated using superconducting hybrid materials provide a highly controllable route toward one-dimensional topolog…
