The Smallest Shor’s Algorithm Estimates Rely on Slow Runs and Hardware Not Yet Demonstrated

Researchers have fit Shor's algorithm into 9,739 neutral-atom physical qubits, with elliptic-curve runs that lengthen from 10 days to about 1,000 as the count falls. The authors assumed error rates and clock speeds no machine has shown together.
