Electronic Cooling Technology Enables Miniaturization of Quantum Computers

Researchers at VTT Technical Research Centre of Finland have successfully demonstrated a new electronic refrigeration technology that can enable major leaps in the development of quantum computers. Current quantum computers require large, complicated cooling infrastructures based on mixtures of different isotopes of helium. The new electronic cooling technology could replace these cryogenic liquid mixtures and enable miniaturization of quantum computers. The discovery was published in Science Advances. The researchers have developed a purely electrical refrigeration method where cooling and thermal isolation operate effectively through the same point-like junction. In the experiment, the researchers suspended a piece of silicon from...
