So when does this break crypto and Bitcoin and how to best prepare for this? Is there any way to secure at all?
Earlier quoted context omitted.
Based on what i read it seems a lot of algorithmic work is required to even make them useful. New algorithms have to be discovered and still they will only solve only a special class of problems. They cant do classical computing so your NVIDIA GPU probably may never be replaced by a Quantum GPU.
Quantum computing is a generalization of classical computing. Thus, they CAN do classical computing. But, in practice, it'll be not as fast, more error prone and at a bigger cost.
Can you explain more or share some resources?
What do they mean by >can create an entirely new state of matter – not a solid, liquid or gas but a topological state
See https://en.wikipedia.org/wiki/Topological_order .
Any word if it works without a Microsoft account?
RSA in trouble when?
Please someone give input on this. It's extremely important and worrying.
However, this announcement is a nothing-burger. As I mentioned down-thread, you should view any QC announcement/press-release with extreme skepticism unless it includes replicable (read: open-source targeting hardware other researchers can test on) benchmarks for progress on real-world use-cases (e.g., Shor, Grover, or a newly-identified actually-interesting use-case). OP does not. Nothing to see here.
Worth saying, I am not a cryptographer—I do cryptography-adjacent research engineering. However, given the level of hype going around this industry, I think it's fair to at least expect to see the spec-sheet as it were.
All the best,
My first scan parsed that as "Marijuana 1 quantum processor". Very high performance ...

No. The long explanations boil down to this: quantum computers ( so far ) are better ( given a million qubits ) than classical computers at ( problems that are in disguise ) simulating quantum computers.
given a million qubits ... also last time I checked the record was 80 qubits and with every doubling of the cubits the complexity of the system and the impurities and the noise are increasing. so it's even questionable whether there will ever be useful quantum computers
Microsoft's technology is pretty far behind as far as capacity but the scaling limitations are less significant and the error-correction overhead is either eliminated or smaller.

So what is it called then
It's a topological superconductor.
