A Quote by Seth Lloyd

When you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.
We couldn't build quantum computers unless the universe were quantum and computing. We can build such machines because the universe is storing and processing information in the quantum realm. When we build quantum computers, we're hijacking that underlying computation in order to make it do things we want: little and/or/not calculations. We're hacking into the universe.
The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer.
What has happened is that we have seen a shift in the past twenty years in the very concept of hacking. So hacking twenty years ago was a neutral, positive concept. Somebody who was a hacker was someone with advanced computer skills, which could expose vulnerabilities and could explain why systems worked well or worked badly and they were generally regarded as an asset. Over the past twenty years, a combination of media and law enforcement has changed the perception of the concept so that it has almost always, if not invariably, a pejorative sense attached.
My hacking involved pretty much exploring computer systems and obtaining access to the source code of telecommunication systems and computer operating systems, because my goal was to learn all I can about security vulnerabilities within these systems.
The first thing I think, I was building computers, I started to build a computer when I was 17 or 18 at home, an IBM compatible computer, and then I started to sell computers, and when I sold a computer to a company called Ligo I think, and they were selling systems which became blockbuster.
The Hacker Ethic: Access to computers--and anything which might teach you something about the way the world works--should be unlimited and total. Always yield to the Hands-On Imperative! All information should be free. Mistrust authority--promote decentralization. Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position. You can create art and beauty on a computer. Computers can change your life for the better.
[With quantum computers] you can calculate how many bits are in the universe, how much energy it takes to flip them, how much energy exists, and use that to rule out lots of things about the universe's history. Anything that takes more bit flips couldn't have happened.
If one ox could not do the job they did not try to grow a bigger ox, but used two oxen. When we need greater computer power, the answer is not to get a bigger computer, but . . .to build systems of computers and operate them in parallel.
Computer science doesn't know how to build complex systems that work reliably. This has been a well-understood problem since the very beginning of programmable computers.
To see a hacker actually hacking is not the most interesting thing visually, and it's pretty boring as an actor: a hacker taps on her keyboard. There's really not much more than that.
As we build systems that are more and more complex, we make more and more subtle but very high-impact mistakes. As we use computers for more things and as we build more complex systems, this problem of unreliability and insecurity is actually getting worse, with no real sign of abating anytime soon.
I took this 'how to build computers' course basically because I'm sick and tired of getting ripped off by cheesy computer companies. Software baffles me. I like hardware. I used to change my own oil, and now I want to build my own computer so I can have what I want.
We build our computer (systems) the way we build our cities: over time, without a plan, on top of ruins
If quantum communication and quantum computation are to flourish, a new information theory will have to be developed.
A hacker is someone who enjoys playful cleverness—not necessarily with computers. The programmers in the old MIT free software community of the 60s and 70s referred to themselves as hackers. Around 1980, journalists who discovered the hacker community mistakenly took the term to mean “security breaker.”
