Abstract

We consider a two-spin qubit that is subject to the orderparameter field of a symmetry broken manipulation device. It is shown that the thin spectrum of the manipulation device limits the coherence of the qubit.

Keywords

qubit manipulation spontaneous symmetry breaking order parameter thin spectrum coherence
