Topic: HONEYWELL Quantum Computer: what does it mean to BTC - page 3. (Read 678 times)

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 do not claim to be an expert in quantum computing or even quantum physics. But I do have some prior knowledge on the subject.

The beauty of bitcoin is that it is open source and allows people to make changes in the code which makes it scalable and relatively adaptable. There are quantum-resistant protocols out there. The threat that quantum computing poses to bitcoin is very much the problem quantum computing poses on any SHA-26 encryption, however, research is already underway to counter this threat.

https://link.springer.com/chapter/10.1007/978-3-030-37110-4_9
This is a link to a research paper that specifically looks into how these protocols can be used to make bitcoin quantum-resistant.

The fact bitcoin uses SHA-26 encryption is nice because it means when an industry-standard algorithm comes out to provide quantum-resistant encryption, it can easily be adopted by the users of the network, and network users will have the incentive to make the switch.

The threat lies between now and when these algorithms are available. I'm not worried so much about Honeywell or another research quantum-computer being used to launch a 51% attack on the BTC network, I'm more worried about a nation-state like China trying to use the technology to take down bitcoin, but I will say that with the power quantum-computers have, I'm sure bitcoin isn't high on the list of targets for quantum-cyber attacks, I would assume China would be more interested in using that technology against other quantum-computing capable nations.

I didn`t claim to have any knowledge or expertise on quantum computer; I am just curious about the industry and how beautiful they are bringing technology from our current state to the future.

However, this topic may supply ideas about how quantum worked as it is. Well to summarize its ultimate function here`s the first, traditional computing bits are in a state of either “0” or “1”, which mean it cannot solved easily the problem. With quantum computer, both 0s` and 1s` are working simultaneously, making it possible to solved problems with multiple probable solutions, this is called “quantum superposition”. This is in fact the science of quantum physics.

As I`ve do the math in google, I found out that it can really poised risk on certain features which is underlying on blockchain technology to mostly in its minimal, to mention few are “How Private Addresses might compromised its encryption and mining capabilities”.

Well, forget about adresses because it is prone to hack but to mining industry, its risky knowing super computer with huge computing power can do the algorithm faster than the actual mining state. If one miner can gain access to quantum computer, they could produce hashes very quickly and gain dominance, leaving the network exposed to 51% attack.

Self Reflection

Which off-course, on my views could possibly be risky, however, given that bitcoin developers are not behind  of such technology - perhaps "quantum resistant encryption scheme" might work...
