Encoding quantum information in states of light
"use superconducting circuits to generate, stabilize, and control qubits based on Schrödinger cat states which inherently resist bit-flip errors... bit-flip suppression rises exponentially with number of photons contained in coherent state... 6 order magnitude increased bit-flip time, from few ms to >10 sec... 60X fewer resources... microwave photons propagating in coaxial cables... cooled near absolute 0, to avoid spurious thermal photons... trap microwave using superconductors... 2-photon dissipation to avoid microwave loss"
