Advancing NMR Spectroscopy on Noisy Quantum Devices

Understanding and Overcoming Noise in Quantum Simulations of NMR

Simulating nuclear magnetic resonance (NMR) spectroscopy on current quantum computers requires tackling the inherent noise found in today’s devices.

In this collaborative study, HQS Quantum Simulations tested small organic molecule NMR simulations on both IBM superconducting qubits and IonQ trapped ion systems.
We systematically analyzed how device noise impacts NMR spectra and introduced a quantitative decoherence threshold to assess algorithmic robustness.

Our noise analysis enables improved spectral accuracy, guiding the way for more effective, application-driven quantum chemistry simulations on Noisy Intermediate-Scale Quantum (NISQ) devices.
