Quantum heat pump (IMAGE)
Caption
An illustration of the device, which consists of two superconducting circuits: a cold high frequency circuit (in blue) and a hot low frequency circuit (in red). Here, the current that flows in the red circuit generates an oscillating magnetic field which leads to the photon-pressure coupling. By sending in a strong signal to the blue high-frequency circuit, this one is transformed into an amplifier capable of detecting radio-frequency photons flowing in the red circuit with much higher sensitivity.
