Quantum Winter Is Coming

[ny_quant]

"The most likely scenario (call it “Quantum Winter”) quantum computing devices remain noisy and never scale to a meaningful quantum advantage… After a tremendous amount of public and private monies are spent pursuing quantum technologies, businesses in the field are limited to research applications or simply fail, and career paths wither."

“The number of known quantum algorithms, which promise advantage over classical computation, is just a few (and none of them will "solve global warming" for sure). More importantly, exactly zero such algorithms have been demonstrated in practice so far and the gap between what’s needed to realize them and the currently available hardware is huge, and it's not just a question of numbers. There are qualitative challenges with scaling up, which will likely take decades to resolve (if ever).”

“As more money flowed [into quantum computing], the field grew, and it became progressively more tempting for scientists to oversell their results… After a few years of this, a highly exaggerated perspective on the promise of quantum computing reached the mainstream, leading to… the formation of a classical bubble.”

В то же самое время 4 дня назад Белый Дом объявил о подготовке к переходу всех федеральных агенств на quantum-resistant cryptography :)

Пока планируется, хы-хы, планирование и анализ, и всё еще может закончится пшиком, но наводить шухер во всей федеральной бюрократии - это само по себе серьезно.
