Inspired by the Random Phase Approximation method, our recent article demonstrates how to map molecular problems onto quantum hardware without the need to brute-force the entire Hilbert space: arxiv.org/abs/2603.09631.

System-bath model for quantum chemistry

We propose an approximate mapping of a molecular Hamiltonian to a Hamiltonian of qubits, which allows for high accuracy quantum chemistry calculations of vertical excitation energies of some molecules...

Unlocking quantum computing's potential requires more than hardware; it needs real-world applications like spectroscopy. Our HQS Qorrelator App and HQSpectrum are bridging quantum hardware with industrial value.

My background is in quantum computing, but I also love building practical tools that improve everyday scientific work. With Gibbon, we turn spectroscopy data trapped in PDFs and figures into reusable digital information. This feature is coming soon.

Theoretical simulations are essential for enhancing the insights we obtain from electronic spectroscopy, given its extensive range of applications. This serves as the driving force behind our research endeavors. Check out the full lecture here: www.youtube.com/watch?v=xnLD...

On May 19th, HQS is hosting a webinar focused on extracting structured, reusable knowledge from data. This includes exploring how tools like HQSpectrum can assist with complex systems and challenging tasks such as impurity analysis. Register here: forms.cloud.quantumsimulations.de/hqs-webinar-...

When ratios matter, quantitative NMR is a key solution for mixture analysis. Let us examine how the ¹H NMR spectrum at 500 MHz changes from pure propanol through various concentration ratios to pure butanol. This illustrates an important challenge in qNMR: spectral overlap.

We’ve successfully computed NMR parameters for over 10,000 molecules, putting our task infrastructure to the ultimate test! 🚀 Curious about how we achieved this? Dive into our workflow in this insightful talk: www.youtube.com/watch?v=eI0S...

This figure highlights why NMR is such a compelling application: it combines structure determination and mixture analysis in one workflow and shows that even molecules with the same molecular formula can yield clearly distinct spectra. Check out arxiv.org/abs/2506.15426

We built a classical NMR solver that scales linearly with molecule size and then asked whether a quantum computer could do better. For most standard NMR experiments? Probably not. Check out www.youtube.com/watch?v=F9WX...

Can a Quantum Computer simulate NMR spectra better than a classical one?

HQSpectrum facilitates your workflow from molecule selection to NMR spectrum calculation in just a few simple steps.

Two Alcohols, One Spectrum: NMR analysis of a mixture of ethanol and 2-propanol reveals characteristic regions of the spectrum corresponding to each component. However, the analysis becomes more complex in regions where the signals overlap.

Simulating realistic NMR spectra can be computationally intensive as systems grow. Our approach: compute spectra in the frequency domain, exploit symmetries, and use spin clustering with adaptive grids to dramatically reduce computation time —from hours to minutes on a laptop.

Triphenylphosphine oxide is an unusually challenging molecule to simulate due to its high symmetry and heteronuclear coupling to phosphorus (read more: arXiv:2508.06448). How would the spectrum appear if we removed the effects of the phosphorus couplings?

Conformer generation + careful thermodynamic averaging is not a nice-to-have, but essential—especially when energetically degenerate conformers are involved.

In a recent video, two HQS colleagues break down a “tier list” of numerical methods in quantum chemistry and solid‑state physics. This was a live recording at our summer All-Company meeting in 2025, so the answers are not scripted and somewhat lighthearted. youtu.be/ltOpQ6FwRiQ?...
