Record Cold Quantum Refrigerator Paves Way for Reliable Quantum Computers

Record Cold Quantum Refrigerator Paves Way for Reliable Quantum Computers

January 9, 2025
Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero. Now, 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, paving the way for more reliable quantum computation.
