For quantum computers to break RSA2048, the current quality of physical qubits needs to go up 10x and the quantity needs to go up 10000x. These are rough numbers. The next major milestone to watch for is a logical qubit with fidelity 1000x better than the physical qubits making it up. That will signal the physical qubits are good enough that you could start only scaling quantity.
