Large-scale NMR simulation on a trapped-ion quantum computer
Researchers used Quantinuum's System Model H2 trapped-ion quantum computer to perform an end-to-end digital simulation of NMR spectra for 1,2-di-tert-butyl-diphosphane, a molecule they describe as classically challenging. The implementation is reported as hardware-efficient, though the abstract does not include quantitative accuracy results.

This could make trapped-ion devices a reference method for calculating NMR parameters of small organophosphorus molecules that classical DFT struggles with, if simulated shifts and couplings match experimental values.
System Model H2 is currently operational and the chosen molecule is a known benchmark for classical NMR prediction. The near-term path is to validate simulated spectra against experimental data, and chemistry groups already use quantum hardware for small-molecule electronic structure.
