Superconducting qubits coupled to torsional resonators.

Journal of physics. Condensed matter : an Institute of Physics journal

Hwang MJ, Choi JH, Choi MS.
PMID: 21403280
J Phys Condens Matter. 2010 Sep 08;22(35):355301. doi: 10.1088/0953-8984/22/35/355301. Epub 2010 Aug 10.

We propose a scheme of strong and tunable coupling between a superconducting phase qubit and a nanomechanical torsional resonator. In our scheme the torsional resonator directly modulates the largest energy scale (the Josephson coupling energy) of the phase qubit,...

Nam SY, Choi IJ, Ryu KH, Park BJ, Kim YW, Kim HB, Kim JS.
PMID: 25843077
J Neurogastroenterol Motil. 2015 Mar 30;21(2):247-54. doi: 10.5056/jnm14114.

BACKGROUND/AIMS: Although adipocytes secrete inflammatory cytokines and adipokines, their role in reflux esophagitis is controversial. We investigated the association between visceral fat and inflammatory cytokines or adipokines in reflux esophagitis.METHODS: Abdominal visceral fat and cytokines were measured in 66...
