effect to flux bias the fluxonium
qubit. We demonstrate how this coupling can be used to sensitively identify
topological superconductivity, to measure the state of the Majorana qubit, to
construct 2-qubit operations, and to implement quantum memories with
topological protection.
Proposal for coherent coupling of Majorana and fluxonium qubits
We propose to use an ancilla fluxonium qubit to interact with a Majorana
qubit hosted by a topological 1D wire. The coupling is obtained using the
Majorana qubit controlled $4pi$ Josephson
