Two atoms inflated to an almost comical size and cooled to a fraction above absolute zero have been used to generate a robust, insanely fast two-qubit quantum gate that could help overcome some of quantum computing's persistent challenges.
Since a two-qubit gate is the fundamental building block of efficient quantum computers, this breakthrough has huge implications. It could lead to a new type of quantum computer architecture that breaks through current limitations for noise-free quantum operations.
