Summary
An international team of physicists at the University of Vienna has discovered a new class of magnons—short-wavelength magnons—that live a hundred times longer than previously known magnons. This breakthrough addresses the key limitation of too-short lifetimes that has held back the use of bosonic quasiparticles like magnons in on-chip quantum information technologies. The extended lifetime could enable scalable quantum technologies at the nanoscale.

· 2 pulledBosonic quasiparticles such as magnons show much promise for enabling on-chip quantum information technologies that can be scaled down to the nanoscale, but their too-short lifetime has held back such applications until now.
An international team of physicists says it has now increased this lifetime by a hundredfold, thanks to the discovery of a new class of magnons known as short-wavelength magnons.
Discovery could help in the development of on-chip quantum information technologies that can be scaled down to the nanoscale
