We present a protected superconducting qubit based on an effective circuit element that only allows pairs of Cooper pairs to tunnel. These dynamics give rise to a nearly degenerate ground state manifold indexed by the parity of tunneled Cooper pairs. We show that, when the circuit element is shunted by a large capacitance, this manifold can be used as a logical qubit that we expect to be insensitive to multiple relaxation and dephasing mechanisms.

Spectrum and Coherence Properties of the Current-Mirror Qubit
A quantitative analysis of the current-mirror qubit predicts coherence times above one millisecond in its protected regime, with charge noise and dielectric loss as the limiting channels.
