Super cold atoms could solve a quantum computing conundrum

Ultracold atoms that constantly move in repeating patterns, in a form of matter called a time crystal, could be used to build quantum computers that produce fewer errors.
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”.…
