Protecting coherence is the main difficulty hindering the development of powerful quantum computers. An international team of researchers (Finland, UK, USA – Yale University, Russia) cooled superfluid helium-3 to within one ten thousandth of a degree from absolute zero and created two time crystals inside the superfluid. They observed an exchange of magnons between the time crystals leading to opposite-phase oscillations leading to opposite-phase oscillations in their populations while the defining periodic motion remains phase coherent throughout the experiment. The findings offer a basis to further investigate the fundamental properties of these phases, opening pathways for possible applications in developing fields, such as quantum information processing…read more.
