Revolutionary Radiation Detector Detects Trillionth of Usual Scale.
Researchers have developed a nanobolometer that can accurately measure power at a scale that's a trillion times smaller than what's possible with standard instruments. The new system could be used to better prepare and calibrate qubits in quantum computers to ensure they're operating as intended and that the readings they produce are correct. The nanobolometer can detect very tiny energy shifts made by very weak microwaves, making it possible to measure radiation temperature without interference from the qubit circuitry. The approach is scalable and doesn't use much energy while eliminating any potential interference for the qubit.
