Abstract
We have demonstrated stable running-mode operation of a superconducting quantum interferometer whose Josephson junction shunts are capacitively blocked in order to cut the signal-band noise currents. An intrinsic energy resolution of 26 times the Planck's constant was reached, which is compared against a numerical estimate obtained in the noise downmixing picture.
