Quantum technology has reached a turning point, echoing the early days of modern computing. Researchers say functional quantum systems now exist, but scaling them into truly powerful machines will require major advances in engineering and manufacturing. By comparing different quantum platforms, the study reveals both impressive progress and steep challenges ahead. History suggests the payoff could be enormous—but not immediate.
There’s an area of research producing “quantum ready encryption”, which uses algorithms that are believed to be secure against quantum attacks. There’s been no wholesale migration to this yet, and the protection remains hypothetical until the attacks actually happen.
