One of the main challenges of implementing this strategy is minimizing the amount of stray optical radiation that impinges on the superconductor, which generates quasiparticles that cause qubit decoherence. We demonstrate a technique for aligning the optical mode to the BAW resonator near the qubit. We also present our first results from an experiment that studies the detrimental effects of laser light on our microwave circuitry.
