‘Time crystals’ work around laws of physics to offer new era of quantum computing

The connecting of two “time crystals” in a superfluid of helium-3 barely one-ten-thousandth of a degree above absolute zero could be a huge step towards a new kind of quantum computer.

Time crystals are bizarre structures of atoms, the existence of which was only predicted as recently as 2012, with experimental proof following a few years later. In a normal crystal, such as diamond or salt, the atoms are arranged in a regularly repeating spatial pattern – a lattice or similar framework. And like most materials, when the atoms are in their ground state – their lowest possible energy level – they stop jiggling.
