Quantum Computers and blockchain
-
I have been asked my opinion on quantum computers and the blockchain.
I have done a lot of “work / research” on Quantum theory, which was part of my physics degree, resonance and impacts (bangs), as part of my PhD and industrial consultancy.
I was also an industrial EngD / PhD supervisor for numerous Artificial Intelligence techniques, agents and data fusion frameworks projects at Manchester University.
My current opinion on Bitcoin and Quantum computing is, once Bitcoin is effected by QC, every other system in the world would already be wide open.
However, I believe the current state of Quantum computers and Data fusion (spying on population and categorizing people by their beliefs / threat level …) is sectret (sic), so it is already cracked. Like with “Enigma”, they can’t use the crack as we’d know and do something about it like change the algorythm … Probably the easiest hard fork too get agreement for, FTC would ever do …
Interested to hear anyone else’s qualifications to comment. :)

If someone has a secret like that it would only be a matter of time before 1 someone else does it or 2 people figure out it is known for the very reason that things people shouldn’t know are known or 3 it is leaked.
This is all pretty moot as we know it is a matter of time before generic quantum computers are created/sold. As soon as they are there will be ramp up time to become wide spread, mean while a migration to a new technology that doesn’t use the difficulty to factor large numbers made of two primes as it’s core security. (General Quantum computers crack this using shor’s algorithm)
In short, if someone has this they are their own bottle beck right now and it means the trillions of various encrypted systems are for the most part completely safe. Especially considering the fleeting nature and re-encryption on a message by message nature of so many communications
