time 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(3d vectors instead of 2d)
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.
firstly the path of bits a quantum system follows to get to the destination is different then the path a binary system would. so trying to go from a binary problem to a qubit puzzle thenback to a binary solution will not always get the intended binary result

take for instance
needing to get to 256
in binary its answer is 11111111
in quantum(0,1,2,3) it could be
3333 using jsut 4 bits, where if 3 represents 1v in qubit would be 1v in binary thus 1111
thus not the answer a binary system would recognise as 256 but instead as 16
thus a translater that turns each qubit into 2binary bits.
q0=b00
q1=b10
q2=b01
q3=b11
thus reducing the efficiency of the process by having to decompress quantum to binary per try

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


p.s
those who have read stories that its wormhole tech/alternative universe/different dimension sci-fi.. its not. its just the patent owners are deliberately trying to be deceptive about the meaning of different dimension. to avoid competitors from stealing the real concepts and making better alternatives faster and cheaper before the patent owners get their competitive head start

if you want to avoid the myths.
binary has 2 'gates' quantum has 4 'gates'
(well some researchers are now seeing how practical/possible it would be to measure 8 gates.. but thats for future generations to play with)

hopefully i dumbed things down enough for beginners

I don't think that's accurate - I know we've been here before though. The advantage of quantum processing is in the superposition, the ability to explore many paths at once - but it still resolves to a classical 0/1 outcome.

For Honeywell specifically, I am skeptical because of the metric they've chosen to use:

I've shared this a few times, and make no apology for doing so again - it's all open to discussion of course, I'm not claiming to be any authority on the subject, just an enthusiast - but here's my summary of how quantum computing can and will affect bitcoin:

Well it depends on what they use it for I guess. I am more concered about super computers in general like when a computer is smarter then all the human brains in the world combined we are screwed! we will end up living in a terminator world someday

Certainly. It would be a global cryptography crisis, which would lead even to a cyber security crisis which would lead to an even bigger financial crisis.

Additionally, it is silly to believe that proccessing power would develop and cryptography wouldn't develop at the same time. As proccessing power goes up, cryptographers will create new and more complex solutions for those super computers to solve.

How can one develop a supercomputer if one doesn't have a superbrain? There is no need to be concern at this point and I believe whoever has that much brain, they will not risk human race. They will indeed make sure that it is developed for our interest or they won't develop at all.

The usage of quantum computer are not for public use yet, and the companies that are using building their quantum computer are only on its test phase, like Google for faster webcrawling algorithm and whatnot, the public usage of quantum computer is still a long way because as I said before they are still on the test phase and even if they have it already, they will use it probably for complex equations such as precise landing for space exploration and such, the quantum computing does not pose a threat in my opinion because we are reaching a plateau in computing speed and quantum computing will be the solution.

What if they put a quantum computer inside a bunker?The problem with vibrations might be solved.
Anyway,I think the quantum computers are way over-hyped as a technology,kinda like the blockchain technology.They are still very expensive to create and implement and they still have major flaws.
I'm no expert in quantum computers,but I assume that they will become a thing after 20 years.
There's still time for Bitcoin/blockchain technology to improve .

QCs aren't magical tech given by some unearthly being. While we don't fully understand the realm of quantum physics yet, several advancements on the field has led us to exploiting and perusing quantum superposition in computing. This isn't exactly as scary as some people are trying to imply. Think of it as a very good computer being a lot more accurate and a lot more faster than the fastest computer that we have today, and that's what you get. By the time we reach QCs with enough capability to render most crypto algorithms useless, we are already ahead of said tech and exploits used by QC won't affect said algorithms. Heck, even before a commercially-produced QC is in the market, we are already developing several quantum-resistant algorithms capable of withstanding attacks from a QC. The tech is good and promising, but crypto enthusiasts know that they need to be always ahead of the tech by a mile, and I'm pretty sure BTC devs are in the same line of thinking so I think we'll be good.

Yes Quantum computers are commonly used by hackers to hack This is not a very secure computer they have all the access In that case they get our personal information very easily. With technology, this computer will never be able to rise because its circulation is much less There is not much interest in using this computer when working in crypto.

It isn't just physical vibrations, it's any interaction with the world outside the quantum system. The system needs to be perfectly isolated - or as near perfect as can be managed. Any interaction can lead to loss of information through the collapse of the wave function. Electromagnetic fields or any form of radiation can trigger loss of quantum coherence. This is why quantum computers have to be cooled close to absolute zero.

The biggest challenge to developing a workable, large-scale quantum computer is not simply increasing the number of qubits to increase the processing power, it's reducing decoherence to a manageable level. Obviously as we add qubits then decoherence becomes more of an issue, because we increase heat in the system - but it is this decoherence rather than number of qubits that is the primary obstacle.

We also need to understand that the underlying physics here - interaction with the outside environment leading to collapse of the wave function - is precisely what allows measurement of a quantum system to occur in the first place. Where a normal classical bit can be 0 (off) or 1(on) depending on flow of current, a system of entangled qubits is more of a probabilistic smear of values across 0 and 1 and everything in between. When we then try to take measurement, we collapse the wave function into a definite 0 or 1 value. This is how quantum computers work, and how (in certain circumstances and for certain use cases) they provide a phenomenal advantage over classical computers. QCs can, through entanglement, process many possibilities at once, whilst still, through collapse, evaluating to a definite binary yes/no end state.
