Sooner than expected? Useful quantum error correction promised for 2028.
Summary
Ars Technica covers near-term promises of useful, error-corrected quantum computing by 2028, highlighting Amazon and QuEra's Libra hardware and advances in neutral-atom and trapped-ion qubits. The piece explains logical qubits and error correction, discusses how quantum advantage may differ from classical algorithm improvements, and notes the potential implications for cryptography and scientific computing.
