00:00In 2016, a group from the University of Maryland captured 10 ions of Iterbium and excited them with lasers.
00:07The ions began to flip periodically, not at the excitation period, but at a double period.
00:13This was the first time crystal ever observed.
00:16In 2017, a group from Harvard University used diamond doped with nitrogen.
00:20Again, stable oscillations appeared that did not directly follow the excitation.
00:25Later, other systems were added.
00:27In 2021, Google used its sycamore processor to demonstrate a time crystal phase that lasted thousands of cycles.
00:35In the same year, a group of German and Polish researchers managed to create a space-time crystal the size
00:41of a micrometer made from a spin wave even at room temperature.
00:45With the help of an ultra-precise x-ray microscope, they managed to capture its recurrent periodic magnetization structure on
00:54film.
00:54Time crystals were no longer just a theory.
00:58They had become real.
