Tiny but powerful quantum refrigerator (IMAGE) Chalmers University of Technology Caption The new quantum refrigerator – the square object in the centre of the qubit in the image – is based on superconducting circuits and powered by heat from the environment. It can autonomously cool qubits to record low temperatures, paving the way for more reliable quantum computers. The device was fabricated in the nanofabrication lab Myfab at Chalmers University of Technology in Sweden.
