Decoherence in a Pair of Long-Lived Cooper-Pair Boxes
V. Zaretskey, S. Novikov, B. Suri +3
We have investigated the decoherence of quantum states in two Al/AlOx/Al Cooper-pair boxes coupled to lumped element superconducting LC resonators. At 25 mK, the first qubit had an…
Spectroscopy of a Cooper-Pair Box Coupled to a Two-Level System Via Charge and Critical Current
V. Zaretskey, B. Suri, S. Novikov +2
We report on the quadrupling of the transition spectrum of an Al/AlOx/Al Cooper-pair box (CPB) charge qubit in the 4.0-7.3 GHz frequency range. The qubit was coupled to a quasi-lum…
Decoupling a Cooper-pair box to enhance the lifetime to 0.2 ms
Z. Kim, B. Suri, V. Zaretskey +5
We present a circuit QED experiment in which a separate transmission line is used to address a quasi-lumped element superconducting microwave resonator which is in turn coupled to…
Anomalous avoided level crossings in a Cooper-pair box spectrum
Z. Kim, V. Zaretskey, Y. Yoon +5
We have observed a few distinct anomalous avoided level crossings and voltage dependent transitions in the excited state spectrum of an Al/AlOx/Al Cooper-pair box (CPB). The device…
