How Shor’s Algorithm Threatens RSA: Quantum Steps to Break Encryption

Shor’s algorithm leverages quantum parallelism to efficiently find integer factors, exposing the vulnerability of RSA encryption by locating periodicity in modular exponentiation, and the article outlines a five-step hybrid quantum‑classical procedure—including quantum Fourier transform—to break RSA keys.
