Bolometer operating at the threshold for circuit quantum electrodynamics

Understand

Radiation sensors based on the heating effect of the absorbed radiation are typically relatively simple to operate and flexible in terms of the input frequency.

• Consequently, they are widely applied, for example, in gas detection, security, THz imaging, astrophysical observations, and medical applications.
• A new spectrum of important applications is currently emerging from quantum technology and especially from electrical circuits behaving quantum mechanically.
• This circuit quantum electrodynamics (cQED) has given rise to unprecedented single-photon detectors and a quantum computer supreme to the classical supercomputers in a certain task.
