Quantum Computing: The Important Stuff
summary
Claims that quantum computers will break RSA tomorrow get tempered by specifics: current devices are noisy and non error corrected with around 50 qubits demonstrated, Google’s 52 qubit chip likely shows quantum supremacy for a tailored test but does not solve practical problems, and useful chemistry requires roughly 160 logical qubits after error correction. Hardware paths differ — superconducting chips need dilution refrigerators, trapped ions use lasers — and real, scalable advantage remains an engineering gap, not a solved physics barrier.
