A full-vortex flux qubit for charged particle optics

Quantum Physics 2018-04-30 v4

Abstract

We introduce a design of a superconducting flux qubit capable of holding a full magnetic flux quantum ϕ0\phi_{0}, which arguably is an essential property for applications in charged particle optics. The qubit comprises a row of NN constituent qubits, which hold a fractional magnetic flux quantum ϕ0/N\phi_{0}/N. Insights from physics of the transverse-field Ising chain reveal that properly designed interaction between these constituent qubits enables their collective behavior while also maintaining the overall quantumness.
