It is still orders of magnitude away from breaking RSA 2048 even under the most optimistic assumptions. And qubits double waaay slower than transistors so far.

AES128 / Grover?

Still requires thousands of logical qubits, which would correspond to millions of physical qubits. And this machine isn't even fully there for the physical qubit part. It's like the first step to physical qubits.

Thanks. What order of magnitude qbits would be needed for RSA 2048?
