high-Q microwave resonator in the ultra-strong
dispersive limit where the dispersive shifts largely exceed the spectral
linewidth. In this limit, we show how to map the two eigenvalues of an
arbitrary weight M < N Pauli operator, onto two quasi-orthogonal coherent
states of the cavity. Together with a fast cavity readout, this enables the
efficient measurement of stabilizer operators.
Stabilizer quantum error correction toolbox for superconducting qubits
We present a general protocol for stabilizer measurements and pumping in a
system of N superconducting qubits. We assume always-on, equal dispersive
couplings to a single mode of a
