  • Record cold quantum refrigerator paves way for reliable quantum computers/
  • The image illustrates the working principle of the quantum refrigerator. The device, composed of two qubits - one hot and one cold - cools a third, target qubit. Powered by heat from a nearby hot environment, the quantum refrigerator extracts thermal energy from the target qubit autonomously and dumps it to a cold environment. As a result, the target qubit reaches a high-quality ground state with minimal error, primed for efficient quantum computation. The device was fabricated in the nanofabrication lab Myfab at Chalmers University of Technology in Sweden.
