Trend Technology 8: molecular behaviour modelled directly instead of approximated

Summary

Quantum simulation for drug discovery is the report's eighth emerging technology, modelling molecules directly rather than through simplified approximations. A single protein may contain thousands of atoms whose interactions decide whether a drug binds its target, misses it or causes unwanted reactions. Classical computers cut that complexity down to make predictions, which has typically introduced errors. Quantum simulation instead applies the same physical principles that govern how atoms actually interact, producing a far more faithful picture of how a candidate will fold, bind and behave before lab work begins. Better error correction and hybrid quantum-classical systems have recently made the approach more reliable and compatible with existing workflows. The report says it may open disease targets long considered undruggable, though it does not guarantee a drug.
