Can someone splain to me what Quantum Computing is?
A scam.
Traditional computing uses electronic 1’s and 0’s in its language and processes. Pretty much everything you do on a computer amounts to “yes/no”, “is/is not”, “and/or” and “if/then” processing of millions of 1’s and 0’s every fraction of a second.
Quantam Computing uses particles to express a massive number of “states” in the particle that can process data in more ways the a simple binary “yes/no”, etc...
Think of it this way — How much more efficient is it to use our alphabet to communicate instead of an alphabet that looks like this: 011000111010101 11011000011 11100011001101?
No. I can suggest an analogy to what I think, very vaguely, is going on.In an analog “computer,” a circuit is constructed to have the mathematical properties of the problem of interest. Such a circuit has very high-(negative) gain amplifiers in it, and the circuit uses negative feedback to force the amplifiers into the states required. No actual numerical calculation is involved.Apparently the quantum computer concept is vaguely similar, but capable of very complicated discrete states, such that in principle it can converge on the solution to things like the two very large prime numbers which are the only factors of their product. Since the difficulty of that problem underpins som crucial encryption algorithms, any “computer” concept - however exotic - which could solve that problem quickly (rather than in, say, a million years) readily attracts the attention of security people.
