Researchers at Chalmers University of Technology , Sweden , and the University of Maryland , USA , have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures.
The refrigerator is powered by heat from the environment, powered by interactions between different qubits, specifically between the target qubit to be cooled and two quantum bits used for cooling.
The studied device was fabricated in Myfab , Chalmers University of Technology in Sweden , a nanofabrication laboratory.
The study received support from the Swedish Research Council , the Knut and Alice Wallenberg Foundation through the Wallenberg Center for Quantum Technology (WACQT), the European Union , the National Science Foundation and the John Templeton Foundation .
