IBM is one of many companies working on quantum computers.

About a fifth of all hard-to-correct errors in quantum computers are caused by powerful particles from space hitting the machines. While these cosmic ray errors have been around for a long time. Predictions by scientiststhis first accurate measurement of how often they occur could help future devices to be error-proof.

Normal computers are also prone to it. Cosmic Ray Errorsbut the delicate components that power quantum computers, called qubits, are at greater risk because their fragile quantum states are easily perturbed…
