Quantum computers cannot reduce anything. Quantum computers are just a scam hidden behind weird probabilistic equations, which are very conveniently excluding almost all real life noise. Quantum computers are so weak, that cannot factor a 6-bit number using the almighty Shor's algorithm - which "breaks ECDLP" - the number 35 turned out just too big for reliable factorization
Quantum Computers do not equal Shor's algorithm. I'm pretty sure if they really wanted to they could factor something bigger than 35 though. We're way past that.
Please show me anything quantum, that could factor big numbers (or even small); besides the obvious random search (adiabatic, annealing, etc), which doesn't scale, and is in fact faster on classical computers.
Who is this "we"? All I see is random buzzwords and utter failure. They wanted to factor, and failed miserably. Now there are 127 qbit computers. And they cannot factor 6 bit numbers.
Repeating buzzwords doesn't make it truth.
