Time crystals may make quantum computers more reliable

Time crystals could be used to build a more reliable kind of quantum computer.

In conventional computers, printed circuit boards consist of solid materials like plastic. A circuit board made from time crystals would involve thousands of atoms almost as cold as absolute zero, one of the conditions required for quantum phenomena to unfold. Krzysztof Sacha at the Jagiellonian University in Poland and his colleagues developed a mathematical blueprint for such “temporal printed circuit boards”.
