ColdQuanta recently announced that it can trap and address 100 qubits in a large, dense 2-D cold atom array. What that means is the company is confident that its ultracold atom approach is on the right track and that the cold atom approach offers advantages in terms of scalability and fidelity to power practical quantum computing, according to Paul Lipman, president of quantum computing at ColdQuanta.
While this advance may seem to have appeared out of nowhere, as a modality, the technology behind cold atom-driven quantum computers has been years — if not decades — in the making and has a long research history to back them up.
