"Quantum computers are coming. Should you be excited or worried?"
Evaluating Shor's algorithm threat to RSA-2048. At 0.1% gate error rate, surface code overhead requires ~1,000 to 2,500 physical qubits per logical qubit.
Surface Code Overhead vs Physical Scaling D3.JS DYNAMIC
Logical Qubits Needed

For Shor RSA-2048 execution
Physical Overhead Required
4.1M
Overhead: ~1,000 physical / logical
Surface Code Physics Note: To suppress logical error rates below $10^{-12}$ using topological surface codes with threshold $p_{th} \approx 1\%$, code distance $d = 2\lfloor \frac{\log(P_L / p)}{\log(p / p_{th})} \rfloor + 1$. Each logical qubit occupies $2d^2$ physical qubits plus syndrome extraction ancillae.
