The superconducting quasicharge qubit
Webpair tunneling, i.e. a charge qubit. In such a case, the quasicharge looses dynamics and it can be interpreted as an external charge-o set. For EL=EC. 1, we get ux-onium26,27, a high-coherence implementation of a ux qubit, where a superconducting loop is disrupted by the tunneling of a single ux quantum.
