Magnon lifetime extended 100x paves the way for mini quantum computers

Phys · · 525 words · By University

Researchers led by Wiener have increased the lifetime of magnons to 18 microseconds by using short-wavelength magnons and ultra-pure yttrium iron garnet spheres at extremely low temperatures. This development is presented as a significant step toward creating scalable quantum computers and hybrid quantum architectures.
