Definition
The term, in context
AI-assisted draft · approved dataset
A sub-zeptojoule bolometric energy sensor is a calorimetric device developed at Aalto University and VTT that measures the heat deposited by individual absorbed photons or microwave pulses with sensitivity below one zeptojoule, using a thin, thermally isolated absorber whose temperature change is read out electrically, a precision suited to characterizing the faint microwave signals used in superconducting quantum circuits.
