potential for Shor’s algorithm for 2K public encryption keys 16K — potential for Shor’s algorithm for 4K public encryption keys 32K 64K 256K 1M — unclear what people might actually use 1M qubits for 10M When can we expect even a single logical qubit? Nobody knows for sure, but maybe sometime within
