• Abstract: We perform nanosecond-resolution multiplexed readout on six same-chip superconducting microwave resonators. This allows us to pinpoint the impact positions of ionizing radiation on the chip by measuring the differential time of flight of the generated phonons, inducing correlated errors in the device, thereby implementing an on-chip seismic array. We correlate the phase response of each resonator - a proxy for the absorbed energy - to the distance from the impact point to uncover a millimetric decay length for the phonon-mediated radiation poisoning.

• Attaining near-ideal Dicke superradiance in expanded spatial domains [0.0]
  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.
