Really agree with the point that quantum computing is all hype and no substance, for the things that we are "worried" about.

I did my bachelors thesis in physics on quantum computing 10 years ago. It was as obvious now as it was back then, that the number of qubits required to break anything significant is way too many to withstand the background radiation anywhere in the universe while at the same time being measureable at some point.

The thing is that what we need are entangled qubits, at will as described by the algorithm that we need to perform. When articles come out describing the new number of qubits reached by Intel, they are talking about isolated qubits that are not entangled. Can't do anything fancy with those.

256 qubits that can be entangled however we want would mean something. But it will never happen. We are limited by the physical world we live in.

Were the universe at 0.0001 degrees Kelvin, with no background radiation, we might have stood a chance. But then, we wouldn't be alive.
