A recent study from the University of California has identified a stress-induced source of phonon bursts and quasiparticle poisoning that affects the performance of superconducting qubits. The research found that a silicon crystal glued to its holder exhibited a higher rate of low-energy phonon events compared to a crystal suspended in a low-stress state. The excess phonon event rate in the glued crystal decreased over time, suggesting that relaxation of thermally induced stress between the glue and crystal is the cause of these events. This research provides valuable insights into the degradation of superconducting qubits and could have implications for quantum circuits and cryogenic calorimeters. [Extracted from the article] |
