Summary

Story summary

Companies say they will deliver useful, error-corrected quantum computers by 2028.
Thousands of high-quality hardware qubits are needed to provide redundancy for error detection and correction.
About 100 logical qubits could model simple chemicals, while tens of thousands could break encryption.
Current qubit technologies provide either high quality or large quantity, leading roadmaps to estimate a five-to ten-year timeline.
