ABSTRACT
The temperature dependence of the magnetic penetration depth in a superconductor, in the kinetic inductance limit, is proposed as a basis for a sensitive thermometer. Considered as a bolometer, the noise equivalent power from the sum of the Johnson noise and the preamplifier noise can be reduced to about 7×10-20 W/(Hz)1/2, which is approximately four orders of magnitude below currently realized values.
