8T is not required if the TLS is decoupled from phonons such as in spin systems. See, e.g., C. Durkan, M. E. Welland, Appl. Phys. Lett. 80, 458 (2002).

Usually the bandwidth is in the kHz to MHz range, due to the long cabling between the low temperature device and room temperature equipment and additional filtering against room temperature noise.

SIS detectors are sensitive up to frequencies ∼2Δ/h. For aluminum junctions, which are used in this work, this is around 100 GHz. Niobium junctions are used in astronomy and go up to THz.

SiS>2Δ, the SIS detector is sensitive to (ω > 0. In this case, the PAT is a small correction on a large background current and difficult to measure.

The strong asymmetry in the JQP peak regarding emission and absorption was observed by Y. Nakamura et al. (30). It is also consistent with recent theoretical predictions (31, 32).
