Quantum Computers Constantly Hampered by Cosmic Rays

New Scientist

In separate studies, researchers found that nearly a fifth of all difficult-to-correct errors in quantum computers are caused by powerful particles from space hitting the machines. Researchers at the Massachusetts Institute of Technology set up an array of 10 superconducting qubits inside an extremely cold fridge with radiation detectors close by, and found that 17% of the qubit errors detected were attributable to cosmic rays. A team at the Beijing Academy of Quantum Information Sciences in China also identified a link between cosmic rays and quantum computing errors during their experiment on an array of 31 superconducting qubits.
