Quantum Resource Estimator: Qubits to Break RSA

Interactive resource-estimation simulator: dial an RSA key size and a physical qubit error rate, and watch the surface-code distance, physical-qubit overhead and total fault-tolerant qubit count needed to run Shor's algorithm scale in real time, benchmarked against IBM's qubit roadmap.

Every claim about quantum computers threatening RSA or ECC encryption hides a hardware bill: Shor's algorithm needs real logical qubits, and every logical qubit needs a surface-code patch of many noisy physical qubits underneath it. This simulator makes that bill explicit and interactive — pick an RSA key size and a physical gate error rate, and watch it compute the logical qubit count, the surface-code distance required to hit a target success probability, the physical-to-logical overhead, and the grand total physical qubit count, rendered as a live 3D cube of glowing qubit nodes and checked against IBM's own public qubit-count roadmap.

Dial an RSA key size and a physical qubit error rate to see the surface-code distance, physical-to-logical qubit overhead, and total fault-tolerant qubit count Shor's algorithm would need, checked live against IBM's public qubit-count roadmap.
