Tiny magnetic waves could unlock quantum computers the size of a penny
Physicists have significantly extended the lifespan of magnons, which are tiny magnetic waves used to carry quantum information. This breakthrough could enable the development of ultra-compact quantum computers that fit on a chip.
Why it matters
Increasing the stability of quantum information carriers is a critical step toward making practical, portable quantum computing technology a reality.
A team of physicists has overcome a major obstacle in quantum computing by dramatically increasing the lifetime of magnons, tiny magnetic waves that can carry quantum information. The researchers extended their lifespan from just a few hundred nanoseconds to as long as 18 microseconds, nearly 100 times longer than previously achieved. The advance could eventually help make ultra-compact quantum computers, potentially as small as a 1-cent coin.
