One of the dreams for security experts is the creation of a quantum internet that allows perfectly secure communication based on the powerful laws of quantum mechanics.

The basic idea here is that the act of measuring a quantum object, such as a photon, always changes it. So any attempt to eavesdrop on a quantum message cannot fail to leave telltale signs of snooping that the receiver can detect. That allows anybody to send a

Is there anything that doesnt sound better with Quantum in front of it?

Quantum diarrhea. It definitely sounds a lot worse than regular diarrhea.

Quantum diarrhea...how would you know when you're finished, given that the moment you try and observe it changes...nevermind, that's too disturbing to think about for the moment.

So will quantum Internet offer anything other than better security? Obviously the security aspect is great, but I'm wondering if there aren't other things that can be achieved using the same mechanics...

So as long as the hub is secure, then the network should also be secur

There is always that. Can't guarantee everything.

They're not just hiding it ;)

Somehow I'm thinking my Verizon Fios Quantum was derived from said quantum??????

I once owned a VW Quantum. It was a turbo diesel.

Would have been nice if it couldn't be detected or changed just by looking at it.

Hmm if you can develop a commercial quantum router (reading->routing a quantum packet without changing it), what's stopping someone develop a quantum snooper (only reading not routing)?

The moment you observe it, it collapses to a classical state |finished> or |unfinished> and the measured value is the corresponding eigenvalue. Yes, measuring disturbs the state, but I think in this case that would be desirable.

Well, not quantum internet, but quantum computing, yes. Pretty cool things happen when you apply quantum computing to, for instance, genetic algorithms, but in the end it doesn't actually help... the no-cloning theorem is a total roadblock there. But the moment you measure the fitness of a specific chromosome, the chromosome collapses to a superposition of all chromosomes with that fitness.

You cannot read it without changing its state, thereby letting the original recipient know it's been read.
