tie to uncover the myths of quantum

quantum is not some weird SCI-FI extra dimension.
nor is it creating new things.
instead its just measuring the previously before unmeasurable. and being more accurate than previous technology

take for instance the visual spectrum of light. our eyes only see a mixture of a certain amount of the primary colours.. yet we then made tech that measured infrared and ultraviolet and used it for things like night vision goggles and heat detection

thats quantum. where we first thought the only colours were a mix of the primary colours because thats all we seen previously

..
now quantum computers. is not 0's and 1's and maybe 0's and maybe 1's.. but instead its the new ability to not measure things in only 2 dimensions of 0 and 1. but more dimensions/steps/variables.
take for instance binary being 0 volts of electric as 0 and 1 volt of electric as 1.
and in the past volt meters found it hard to measure 0.33v or 0.66v so people just stuck with 0 and 1 volt and only 2 measures they can use predictable/comfortably without much error

now imagine we can accurately without error measure the difference between 0v,0.33v,0.66vand 1v meaning now we can have 4 variables per pulse/transister instead of 2.

now instead of jsut yes or no/on off/true false. we can have more expressive choices in 4 options
so instead of single direction stop forward. we can have
stop, left, right forward
so instead of single options yes or no. we can have
no, sometimes, most times, yes

all of this opens up more options. allowing a base 2 to become base 4
it allows hex to be stored in just 2 'bits' instead of 4 bits
it allows base64 to be stored in 3 'bits' instead of 6 bits
so 8bits can store a numeric of 65536 instead of just 256

its not some sci fi extra dimensional universe. its just standard 'dimensions' of going from 2d to 3d

..
now that simple lesson has sunk in
quantum computers wont do much for the efficiency of 256bit hashing.. at most expect 2x efficiency gain.
so dont worry much about anyone making a quantum super computer to out hash the network
the millions of binary based ASICS far far far outpace any quantum systems of any scale for the forseeable future

but the signature process of the eliptic curve is more vector based than binary/hex based and binary computers are not good at these vectors, but quantum is.
however this is not some massive change.

and keep in mind if it takes a few eons(millions of millions of years) for binary to brute force  bitcoin signature. it will still take thousands of years for quantum.

..
in short quantum is not some new magic that jsut uses magic glitter dust to come to an answer
it just is a transister based system using 4 options instead of 2. and requires the system to be kept at a very very low temperature to keep it able to measure the smaller variables inbetween
