Quantum Time Crystals Could Be Useful for Quantum Computing
Quantum time crystals are systems characterized by spontaneously emerging periodic order in the time domain. Lancaster University researchers experimentally studied two adjacent quantum time crystals realized by two magnon (magnetic particles) condensates in superfluid 3He-B. They saw an exchange of magnons between the time crystals leading to opposite-phase oscillations in their populations—a signature of the AC Josephson effect—while the defining periodic motion remains phase-coherent throughout the experiment. The results demonstrate that time crystals obey the general dynamics of quantum mechanics and offer a basis to further investigate the fundamental properties of these phases and they could be for real-life applications
