Shor resource estimator

How many physical qubits and how long does a quantum machine need to factor your RSA? Realistic inputs, order-of-magnitude outputs.

RSA modulus bits Typical: 2048. Migration: 3072 or 4096. Physical gate error rate 2026 hardware: ~1e-3. 2030 roadmap: ~3e-4.

These are order-of-magnitude figures. The real number depends on circuit implementation, lattice-surgery routing, and magic-state factory throughput.
