• Abstract: Field emission can cause significant problems in superconducting radio-frequency linear accelerators (linacs). When cavity gradients are pushed higher, radiation levels within the linacs may rise exponentially, causing degradation of many nearby systems. This research aims to utilize machine learning with uncertainty quantification to predict radiation levels at multiple locations throughout the linacs and ultimately optimize cavity gradients to reduce field emission induced radiation while maintaining the total linac energy gain necessary for the experimental physics program. The optimized solutions show over 40% reductions for both neutron and gamma radiation from the standard operational settings.

  Superradiance for arrays of inverted emitters in free space requires interactions far beyond the nearest-neighbor. Epsilon-near-zero (ENZ) materials, which exhibit infinite effective wavelengths, can mediate long-range interactions between emitters. We employ a general method to assess the occurrence of superradiance, which is applicable to various coupling scenarios. The findings of this work have prospective applications in quantum information processing and light-matter interaction.

• Disentangling the sources of ionizing radiation in superconducting qubits [0.0]
  Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. We measure levels of radioactivity present in a typical laboratory environment (from muons, neutrons, and gamma's emitted by naturally occurring radioactive isotopes) and in the most commonly used materials for the assembly and operation of state-of-the-art superconducting qubits. We propose mitigation strategies for the operation of next-generation qubits in a radio-pure environment.
