# Coherent oscillations between classically separable quantum states of a superconducting loop

@article{Manucharyan2009CoherentOB, title={Coherent oscillations between classically separable quantum states of a superconducting loop}, author={Vladimir E Manucharyan and Jens Koch and Markus Brink and Leonid I. Glazman and Michel H. Devoret}, journal={arXiv: Mesoscale and Nanoscale Physics}, year={2009} }

Ten years ago, coherent oscillations between two quantum states of a superconducting circuit differing by the presence or absence of a single Cooper pair on a metallic island were observed for the first time. This result immediately stimulated the development of several other types of superconducting quantum circuits behaving as artificial atoms, thus bridging mesoscopic and atomic physics. Interestingly, none of these circuits fully implements the now almost 30 year old proposal of A. J… Expand
