Cosmic rays and radioactivity may present a challenge for scalable quantum computing, as researchers find they interfere with error correction (John Timmer/Ars Technica)

John Timmer / Ars Technica:
Cosmic rays and radioactivity may present a challenge for scalable quantum computing, as researchers find they interfere with error correction  —  For quantum chips, the problems they cause are too big for error correction.  —  Recently, when researchers were testing error correction …
