Boffins spin a solid state qubit in a nucleus A group of researchers from the University of New South Wales has produced a functioning solid-state qubit with a read-out fidelity of 99.8 percent, taking the world another step along the path towards a functioning quantum computer. The team used the magnetic spin of the phosphorus nucleus as the basis for their experiment, …

...is how many qubits they can entangle without the whole lot decohering. If they want to break 128 bit keys, they will need 128 bits. This new tech will only be interesting if it leads to a massive increase in the number of entanglable qubits...
I think the top number achieved so far is eight. Just enough for a quantum Commodore 64 :D
Am I the only one who thinks we are not socially ready for quantum computing?
I'm not scientist or a computer technician but everything I've read about quantum computers suggests a working model will be something like an electron microscope and an MRI machine. What I mean is that it will require extreme cold, a lot of energy, a dedicated staff of highly specialized operators and a building or two. In other words only those with the cash of governments, large corporations, major institutions and possibly organized crime and rogue states will be able to afford one. Which leaves all the rest of us at their mercy. Considering how well they've handed all the other responsibilities awarded to them by their largess can we really trust them with the ability to see everything?
Well it no longer requires a mist of metal atoms in a UHV chamber and might be reducible to something that (more or less) fits on a chips.
Quantum computing is shaping up to be the GaAs of the 21st century.
The computing technology of the future.
Always was, always will be.
