Actually the idea that quantum computing can solve the travelling salesman or other similar problems is a myth mostly propagated by journalists and others with a poor understanding of the subject. Some QC researcher cynically avoid undermining this myth because the myth is good for their funding!
Famously QC CAN factor big numbers very fast - but that is only because factorisation is NOT one of the general set of problems to which the travelling salesman belongs. Factoring has more structure than NP complete problems and hence is "easier". It is this structure that Shor's algorithm exploits. So I'd say that the final link in the article is misleading rubbish.
YOu are right - although of course one has to be clear what analog actually means - it DOESN'T mean "continuous" it means "by analogy" as you sort of point out.
To talk about quantum computers "outperforming" classical computers is of course nonsense. Quantum computers are horrendously difficult to "program" effectively. The entire research community has managed to create a set of algorithms that you can count on the fingers of one hand in the last 20 years.
What they can do is provide effective simulation for quantum mechanical systems.

Because H.R. 699 in its current form imposes burdens that will make our job harder without offering any relief in other areas, Hey - I get stuff from our management that make my job harder on a regular basis. I don't get to lobby to change the law - I just have to klive with it. Why should they be any different!
(Especially as it seems that in this case there is a good reason for it. Most of the things I have to put up with don't even have that.)
the UK is one such country that is shutting down websites, all on the say-so of the entertainment industries
Just like the US then - only maybe a bit less so - as usual and almost certainly it is US companies that are dictating.
remembering that the UK has put in place a dedicated police force, using tax payers money, to find and sue as many people as possible.
You're talking about the City of London Police here I assume.
Well it wasn't set up for that - you can't really blame our government directly. It was set up to police fraud in the City of London. However it has taken upon itself the role of copyright cop without anyone (other than the entertainment industry) asking it to do so.
Perhaps it's different in the U.K. Their geography, (Island) combined with their Orwellian style of government, allows them to protect the people while simultaneously removing their freedoms. If that is what they chose to do, then good for them, it is their choice. We on the other hand, had forefathers that had the forethought to write it into our constitution so those freedoms will never be taken away from the people.
Our government is no worse than yours in general - and in many ways it is often better. Only lack of knowledge could lead you to that accusation.
Your forefathers had the stupidity not to realise that times would change and allowing everyone to arm themselves would in the end just result in more death - often accidental.
Plus you don't really follow the 2nd amendment anyway because not ALL types of weapons are allowed.
Plus - your law enforcement is more aggressive and extreme than ours. Reading all the articles about police brutality and asset seizure in the US and comparing it with the UK where these things are somewhere on the spectrum between rare and unknown has convinced me of that.
Plus many of the worse cases of injustice in the UK in frecent years have occurred at the instigation of US corporations or the US government.
Actually it would make more sense to turn the no-fly list into a no gun list and stop using it as a no fly list. That way at least, fewer people would be affected and it would be less disruptive to their lives!
The fact that the republicans want to do the opposite just shows how messed up their thinking is.
