Two-level System Loss: significant not only at Millikelvin
Two-level System Loss: significant not only at Millikelvin
Tow-level system (TLS) loss in amorphous dielectric materials has been intensively studied at millikelvin temperatures due to its impact on superconducting qubit devices and incoherent detectors. However, the significance of TLS loss in superconducting transmission lines at liquid helium temperatures remains unclear. This study investigates TLS loss in amorphous $SiO_2$ …
