Spectral response of Josephson junctions with low-energy quasiparticles
Spectral response of Josephson junctions with low-energy quasiparticles
We study nanowire-based Josephson junctions shunted by a capacitor and take into account the presence of low-energy quasiparticle excitations. These are treated by extending conventional models used to describe superconducting qubits to include the coherent coupling between fermionic quasiparticles, in particular the Majorana zero modes that emerge in topological superconductors, …
