What will Quantum Computing Mean?

A largely non-technical view of what Quantum Computing will mean.  Our own minor investigations looked at how very complex combinatorial problems (problems with many, many solutions) that might then be solved with these methods more easily.   These problems also relate to things like cryptography.

You Won't See Quantum Internet Coming   By Ryan F. Mandelbaum   in Gizmodo.

 The quantum internet is coming sooner than you think—even sooner than quantum computing itself. When things change over, you might not even notice. But when they do, new rules will protect your data against attacks from computers that don’t even exist yet.

Despite the fancy name, the “quantum internet” won’t be some futuristic new way to navigate online. It won’t produce any mind-blowing new content, at least not for decades. The quantum internet will look more or less the same as the internet you’re using now, but scientists and cryptographers hope it could provide protection against not only theoretical threats but also those we haven’t dreamed up yet.

“The main contribution of a quantum internet is to allow encrypted communication in a perfectly secure fashion that can’t be broken in principle, even if in the future we develop a more fundamental theory of physics,” Ciarán Lee, a researcher at University College, London, explained to Gizmodo. In short, the quantum internet would hopefully protect us from planned new computers, along with every theoretical computer for the foreseeable future.

So what’s the quantum internet? It’s what happens when you apply the weird rules of quantum mechanics to the way computers communicate with one another.  ... "
