Quantum resistor-capacitor circuit with Majorana fermion modes in a chiral topological superconductor.

Physical review letters

Lee M, Choi MS.
PMID: 25170724
Phys Rev Lett. 2014 Aug 15;113(7):076801. doi: 10.1103/PhysRevLett.113.076801. Epub 2014 Aug 13.

We investigate the mesoscopic resistor-capacitor circuit consisting of a quantum dot coupled to spatially separated Majorana fermion modes in a chiral topological superconductor. We find substantially enhanced relaxation resistance due to the nature of Majorana fermions, which are their...

Superconducting qubits coupled to torsional resonators.
