@masteroftheschwartz I am more of a nerd than you lol. I have built processors. They aren't stored in transistors. They are stored in the systems that are created by transistors. Transistors make up logic gates, logic gates make up flip flops and latches. Information 1 or 0 is stored in these. The actual transistors don't store information.

[masteroftheschwartz]

@CronosXIIII Actually you can store information with transistors *nerd alert*; the catch is that you have to keep the circuit powered and it takes a lot more space than storing information other ways. So they're only used when you need very very fast memory, e.g. cache memory or register s in the CPU(if i remember right)

[CronosXIIII]

@drnrqsldch Information is not stored in transistors. Transistors are used to create logic gates which are used to create logical desicions.

[SERSOVI]

Really good programm: nice, understandable and quite complete.

@ikkangeen how can u put information in to a transistor? and this is not about store information in to an atom, is to make atoms calculate things instead of transistors. Storage is other stuff.

[drnrqsldch]

there's any need to treat us like kids?

[nardiax1]

is this quantum computing for 5 year olds? worst video ever

Dual-prime factoring only requires basic algebra. The "Sieve of Eratothenes" method is ok for very small dual-primes, but inefficient for large. A trivial example 44377 is a dual prime, it's square root is just under 211, & 211 x 211 = 44521, and 44521 - 44377 = 144, a perfect square, 12 x 12,  so the two primes are 211 + 12 = 223, and 211 -12 = 199. FACTORED! Larger dual-primes need to be made pseudo-square with a suitable ratio. Check:- "Integer Factorization and The RSA Problem" TechRepublic

how can you put information in to an atom wtf? i don't understand that part...can somebody explain?

@paulinapaulette:

You can measure small groups of synchronised atoms which may indeed turn out to be individual atoms themselves. What they say about superposition is badly tisted and misleading representation of reality. State are NOT in both up and down states simultaneously. What superposition is is a Specific random state somewhere in between which can be represented by the vector combination of the up and down states. cf: the compass direction NW being represented by aN+bW where a=-b.
