Abstract
We present a MgB2-based Microwave Kinetic Inductance Detector (MKID) featuring a quality factor Qi ~ 105 and noise equivalent power NEP ~ 10−14 (Formula presented.) at 2 K. In comparison to YBCO-based MKIDs, the MgB2 detector shows greater sensitivity to both temperature and magnetic field, a result of its two-gap nature and relatively low critical (Formula presented.) field. Our data indicate that MgB2 is more advantageous for MKID applications at temperatures lower than 3 K.
