A quantum computer can own this **** up in like maybe a day. maybe less


I knew physics 805 would teach me something
At 1MHz, it would take a quantum computer under 15 seconds to have it cracked wide open.

What is a "Quantum" computer? Quantum is a pretty general word to describe a technology. All modern microprocessors are "Quantum" computers.

Thats just the media talking, people say everything is "quantum" because it makes them look smart.

The main difference is in the way it reads information. Normal computer use bits which are basically just 1s and 0s. I don't fully understand it myself, but Quantum computers have more than just 1s and 0s and as such, that makes them perform differently and enables them to do things that seem impossible on standard computers.

Modern microprocessors are in fact "quantum" computers.

Perhaps what you are referring to is optical processors that use fiber optics and replace 1's and 0's with difference frequencies of light.

Not really, microprocessors are still operating in binary. If you have only two achievable states with a transistor, there's not too many things that transistor can do. If you have more achievable states in a bit, then it becomes worth significantly more.


I end up taking a lot of this junk from Wikipedia, but on the more technical articles it's pretty well written and in depth (although it can require a lot of reading to actually understand it)

I had these on pg4 of this thread btw

(On testing random possibilities)
"Meeting this scalability condition is possible for a wide range of systems. However, the use of error correction brings with it the cost of a greatly increased number of required qubits. The number required to factor integers using Shor's algorithm is still polynomial, and thought to be between L and L2, where L is the number of bits in the number to be factored; error correction algorithms would inflate this figure by an additional factor of L. For a 1000-bit number, this implies a need about 10^4 qubits without error correction.[9] With error correction, the figure would rise to about 10^7 qubits. Note that computation time is about L2 or about 10^7 steps and on 1 MHz, about 10 seconds."

It's an interesting read, at least.
