No... perhaps the methods we use now will be obsolete but that doesn't mean there aren't (or can't be) ciphers too complicated for even quantum computers to figure out in a short enough time.

This is no good explanation at all. The only explanation about quantum computing that he gives is that we can have bits that are in a) multiple states at the same time and b) more than just two states. I accept that some people didn't know that so it might be new information, but it doesn't tell us anything about how quantum computing works.

It explains the quantum, but doesn't even begin to explain the computing.

The day we do get quantum computing, encryption will be a thing of the past. There really will be no such thing as an uncrackable code (where is said code is recallable and usable again).

In other words, it would be a cold day in hell before we get quantum computing.

Your video, Quantum Computing Explained, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

Interesting...but i would have wanted to hear more about the new quantum computers he started to talk about at the end...

I stand corrected. The video was nice (you should post to the sift with the 40 minute offset, and mark as related to this video). But the link you sent mentions (just before the footnotes) that Virtual Currency is not considered "legal tender", and with that, you wouldn't have the same legal problems that the Liberty Dollar had. It also mentions the banking regulations apply to those that convert to/from real currency, not to users.

So, invest all you like in Bitcoin. It will be nice until a (reasonably sized) quantum computer comes around. After that, Bitcoins will be useless (along with all other systems built around asymmetric cryptography).

Of course the entire universe is a quantum computer! When using the earth as one failed, the mice re-contracted to have the entire universe rebooted as one.
Of course, the answer is still 42.
(Douglas Adams)

Women are quantum computers. How else can a man can be wrong even when he's right?

Interested in hearing what sort of potential application this can have. Computing? Communications? A new type of vibrating/non-vibrating Dildo?


Quantum computing, first off. But, putting even larger objects in superposition could allow us to do truly awesome and odd things; especially, if combined with entanglement.

But, for now the first things up are quantum cpus, communications (cryptography), nanotechnology, etc...

Quantum Computation is child's play...

It's the math that kills you!

@MaxWilder "But until it affects my life directly in one way or another, I have no reason to believe it either. I am neutral on the subject."

But what if I ask you directly : Does something like a Universe-level consciousness exists? Even if you answer that you don't have an opinion about it, you must believe in something: that the chances for its existence are 50-50, etc. And then, if you are an astronomer and must construct a theory on the workings of the Universe, then you MUST be believing either that the Universe forms a consciousness or that it doesn't since either theory imply many things as to the functioning of the Universe. Of course, it all depends on the definitions of "consciousness" and "Universe",etc. but if you don't like the definitions, tell us yours and whether you thus believe that the "Universe" is "conscious" or not. You may cry foul and go to quantum physics, but the brain is not a quantum computer. Your brain has a belief about a Universe-level consciousness, in one form or another, you simply just don't admit it.

Anyway, what I was trying to say is that there is nothing wrong in believing that God doesn't exist. Believing that the act of believing itself is wrong is already conceding to the theists' argument that belief is somehow strictly part of the religious phenomenon. "Beliefs" are a mental shortcut we humans have and need to function efficiently. Belief in something does not imply blindness to the shortcomings of beliefs. Thinking there are shortcomings to beliefs is a belief in itself. What I am saying is that there is no problem with beliefs, only problems with certain kinds of beliefs.

Beliefs are more general than you think, and this may be why you believe you can have a "no belief" about something. What you must understand is that a belief is not an opinion, nor is it a logical or statistical argument.

This explains my relationship with Jesus Christ to the T. When I go door to door, I bring my Bible and a box of whip-its.

Just dont do what I did, I went to Best Buy and bought the Nvidia Quantum Computing card, which comes with a can of Rubidium, but then we all huffed the Rubidium because you get to meet Jesus for about 10 minutes.

I did my master's thesis on some of the weird quantum effects he mentions at the very end. Such a cold cloud of gas can actually work as a quantum computer.
