Observation of Regular Oscillations in Magnetization with a Quantum Computer

A research group including Senior Research Scientist Tomonori Shirakawa demonstrated that discrete time crystals and discrete time quasicrystals can be stably realized for up to 100 time steps on a 133-qubit two-dimensional lattice using IBM’s superconducting quantum computer (here, one time step corresponds to one period of the drive).

This result is expected to contribute to experimental validation toward digital quantum simulation of two-dimensional nonequilibrium quantum many-body systems, which are difficult to simulate using classical computation.
