Cosmic intruders: Energetic particles from space and natural background radiation can trigger hard-to-correct errors when they collide with chips containing superconducting qubits. (Courtesy: Chris ...

A new academic paper reveals a worrisome tendency for cosmic rays to disrupt quantum computer processors in a way that may be nearly impossible for current error ...

Nearly a fifth of all difficult-to-correct errors in quantum computers are caused by powerful particles from space hitting the machines. While these cosmic ray-induced errors have long been predicted ...

Recently, when researchers were testing error correction on Google’s quantum processor, they noted an odd phenomenon where the whole error-correction scheme would ...
