Cryptography and Quantum Computing Concerns
summary
Claims that Google Project Willow demonstrates error correction and finishes a calculation in under five minutes versus decades on classical machines, and that breaking a 2048‑bit RSA key needs on the order of 2,000–3,000 qubits, while current devices show ~80 qubits but vendors like D‑Wave announce 4,000–5,000 qubits this year. Shows practical tests: national labs and a Lithuanian university group demoed quantum key distribution but report distance and error‑correction limits, and cloud sandboxes (IBM, Google, Azure, AWS) host early experiments.
