It's not nanotech, except in the sense that anything small and interesting enough counts as nanotech. But it's a significant milestone toward a game-changing technology.
An electronic quantum processor with two qubits, each made of about a billion aluminum atoms, has been created at Yale university. They can get the qubits to maintain their state for about a microsecond. And they have a "quantum bus" that can pass information between the bits.
I don't understand all the cool things you can do with a quantum computer, but apparently it can be useful for simulating quantum chemistry. I suspect we'll have covalent-solid molecular manufacturing before this quantum computer technology develops to the point where it can help, but I've been surprised before by how fast technologies can advance.
The problems they note is how to extend the lifetime of the entanglement; a week or so before this annoincement, there was a report of using lasers to extend the lifetimes of entanglements.
In short, I expect to see rapid progress in quantum computing; i'm not sure about your(Mr Phoenix) timetable for quantum computing vs whatever level of nanomanufacturing; but, I'm thinking quantum computing comes certainly before daimondoid nanomanufacturing;

Hi,
Scientists have already built basic quantum computers that can perform certain calculations; but a practical quantum computer is still years away.
