Just adding my humble piece here.
Quantic-based computing is only a very vague theory that has been translated into very early practical use-cases.
If I would need to pick an example of the past, it would be like saying that 1946's first computer is able to unlock the 2020 Iphone.
Joke apart, this is not far from this.
Most of the Quantum Computing is made currently within very specific universities and there are around a dozen of startups trying to surf on the wave.
Bitcoin and other cryptographic-based digital assets are safe... for now.
