1000-qubit QC can't break a RSA-2048 key Neither any classical computer can. We don't even have enough harddrive to store all quantum information in a 100 qubi

1000-qubit QC can't break a RSA-2048 key Neither any classical computer can. We don't even have enough harddrive to store all quantum information in a 100 qubit QC, let alone 1000qubit. QC is limited to solve a subset of problems do not automatically equals to QC is useless comparing to classical ones. Also not able to invalidate the powerfulness of QC beyond 100 qubits.
