Circuits and methods related to temperature sensing of regions within a superconducting integrated circuit (IC) using in-situ resonators are described. An example relates to a superconducting IC including a first resonator having a first spatial location in relation to a floor plan of the superconducting IC. The superconducting IC further includes a second resonator having a second spatial location in relation to the floor plan of the superconducting IC. The superconducting IC further includes a feed line configured to provide a test signal to each of the first resonator and the second resonator in order to elicit a frequency response from the first resonator or the second resonator, where the frequency response is correlated with a first region within the superconducting IC corresponding to the first spatial location or with a second region within the superconducting IC corresponding to the second spatial location.
