As they warm up, quantum computers can slow down or stop working altogether. A new kind made with specially engineered diamonds cools as it calculates

Quantum computers made from imperfect diamonds could stop themselves from overheating just by running an algorithm. Most quantum machines must be kept at low temperatures, but “algorithmic cooling” might allow quantum computers to perform well at room temperature in the future.
Conventional computers slow down as they warm up, and quantum computers can even stop working if they get too hot. While classical computers are typically cooled by fans, quantum computers generally require much …
