The Chinese claim they can break RSA 2048, not that they have broken RSA 2048 https://arxiv.org/pdf/2212.12372.pdf According to the article the Chinese have used classical lattice reduction factoring techniques with quantum approximate optimization algorithms to reduce the number of qubits from what we previous thought would take several million qbits to factor down to 372 qbits. D-Wave has announced their 2,000 qbits Advantage 2 Quantum Computer and IBM has announced their 477 qbits "Osprey" Quantum Computer both of which might be useful to test the if the Chinese approach to factoring RSA 2048-bit integers is possible using 372 qbits The Chinese group did not have a large quantum computer to work on so they used 48-bit numbers on a 10qbit quantum computer and extrapolated their findings. Shor’s algorithm is thought possible to scale, however the scaling problems are unknown, however Schneier says there are not obvious barriers to doing it.
