Phonon-Trapping-Enhanced Energy Resolution in Superconducting Single-Photon Detectors

Pieter J. de Visser et al.

Summary: Superconducting detectors with low excitation energy promise high resolving power for visible wavelengths; however, experimental results show that the resolving power is limited by hot phonon loss. By suspending the sensitive part of the detector on a thin SiN membrane, the resolving power can be significantly improved due to stronger phonon trapping on the membrane, indicating a route towards the Fano limit through phonon engineering.

Reducing the impact of radioactivity on quantum circuits in a deep-underground facility

L. Cardani et al.

Summary: As the coherence times of superconducting circuits have increased, they have become a leading platform for quantum information processing, but further improvements are needed. Environmental radioactivity is a significant source of nonequilibrium quasiparticles, introducing time-correlated bursts in resonators and complicating quantum error correction. Operating in a lead-shielded cryostat underground reduces quasiparticle bursts by a factor of thirty, highlighting the importance of radiation abatement in future solid-state quantum hardware.
