Tiny magnetic waves may make it possible to build quantum computers as small as a penny
Physicists have extended the lifespan of magnons—tiny magnetic waves that can carry quantum information—from a few hundred nanoseconds to 18 microseconds, nearly a 100-fold improvement over previous records. This achievement could pave the way for highly compact quantum computers, potentially no larger than a 1-cent coin. Led by Andrii Chumak at the University of Vienna, […]
