Unlike photons, which travel through empty space or optical fibers, magnons propagate within a magnetic solid. Their wavelengths can be reduced to the nanometer range, meaning that magnonic circuits could, in principle, fit onto a chip no larger than those found in today\u2019s smartphones. Furthermore, as an excitation of a solid, a magnon naturally couples to numerous other fundamental quasi-particles\u2014phonons, photons and others\u2014making it an ideal building block for hybrid quantum systems and quantum metrology.<\/p>\n<p>Until now, there has been one major obstacle: magnons have had a very short lifetime. This lifetime\u2014the period during which they can reliably carry quantum information\u2014was limited to a few hundred nanoseconds at best. Far too short for any practical quantum computation. The team led by Wiener has now achieved a breakthrough: the physicists were able to measure magnon lifetimes of up to 18 microseconds\u2014almost a hundred times longer than any value observed to date.<\/p>\n<p>In this state, magnons are no longer fleeting signals, but become long-lived, reliable carriers of quantum information, comparable to the superconducting qubits used in today\u2019s leading quantum processors.
