Physcial qubits currently suffer from noise problems and so logical qubits have to be simulated. You can't just implement them directly in a scalable way in hardware. So, you could say that a meaningful, scalable quantum computer of any kind has not yet been built. You can certainly say that a quantum computer capable of breaking real world encryption is very far from current reality.
- Misdicorl 8y agoSaying there's a lot of work to do and it's unclear whether there will be a practical solution in our lifetimes is very different from calling it a hoax. Comment even makes an absurd appeal to authority. It's intellectually dishonest and doesn't belong here
- wbhart 8y agoHe/she does go on to explain what they mean by that: press releases deliberately talk up the `magical' aspect of quantum computing, and this is at least in part necessary for further funding. You can argue about whether the word `hoax' is warranted. But I didn't misunderstand the sentiment. It's not an antiscience claim, but merely hyperbole to drive home a point.
