Divergences in classical and quantum linear response and equation of motion formulations

2024 · The Journal of Chemical Physics

Calculating molecular properties using quantum devices can be performed through the quantum linear response (qLR) or, equivalently, the quantum equation of motion (qEOM) formulations. Different parameterizations of qLR and qEOM are available, namely naïve, projected, …
Understanding and mitigating noise in molecular quantum linear response for spectroscopic properties on quantum computers

2025 · Chemical Science

The promise of quantum computing to circumvent the exponential scaling of quantum chemistry has sparked a race to develop chemistry algorithms for quantum architecture. However, most works neglect the quantum-inherent shot noise, let alone the …
