Tiny but powerful. The new quantum refrigerator, made of qubits, can be seen as the square chip at the centre of copper housing, and 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.
