Abstract:	We report measurements of the energy resolution of superconducting bolometric detectors with sufficient sensitivity to count single terahertz photons. The detector is a superconducting titanium nanobridge with niobium contacts. The larger superconducting energy gap in the niobium confines excitations in the titanium nanobridge, and the thermal relaxation time is set by electron-phonon coupling in the titanium. A fast microwave pulse is used to simulate a single higher-frequency photon, where the absorbed energy of the pulse is equal to the photon energy. Present devices have a measured intrinsic energy resolution of 6 terahertz, near the predicted value due to intrinsic thermal fluctuation noise.
