Quantinuum and HQS simulate complex molecule on quantum computer
Quantinuum and HQS Quantum Simulations just used a 42-qubit trapped-ion quantum computer to accurately model the NMR (nuclear magnetic resonance) spectrum of a 22-spin molecule that's tough for classical computers. The setup reproduced subtle features—like a double peak in the 3.9–4.3 ppm range—that previous hardware couldn't resolve. This showcases the potential for quantum computers to tackle advanced spectroscopy and materials science problems.
- Simulation covered 21 effective atomic spins
- Used hardware-efficient mapping to lower gate count
- Hit spectral resolution of about 0.07 ppm
- Matched tricky double-peak signature classical computers miss
