This breakthrough extends the lifetime of magnons—the magnetic waves used to carry quantum data—by nearly 100 times, proving that material purity rather than physical laws limits their utility. By overcoming this decoherence barrier, researchers pave the way for ultra-compact hybrid quantum systems and chips potentially as small as a penny.

Tiny magnetic waves could unlock quantum computers the size of a penny

ScienceDailyJuly 2, 20264 min read

A major breakthrough in quantum technology has turned magnons, tiny magnetic waves once considered too short-lived for practical use, into promising carriers of quantum information. Researchers extended their lifetime by nearly 100 times, reaching up to 18 microseconds, and discovered that the main limitation is not a law of physics but the purity of the material itself. That means future improvements could come from better manufacturing rather than entirely new discoveries.

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…
