Quantum Heat Pump Made From Particles of Light
by Brian Wang from NextBigFuture.com on (#633WY)
Physicists from TU Delft, ETH Zurich and the University of Tubingen have built a quantum scale heat pump made from particles of light. This device brings scientists closer to the quantum limit of measuring radio frequency signals, useful in for example the hunt for dark matter. Above-An illustration of the device, which consists of two ...
