From Wavefunction Regularity to Eigenvector Conditioning: Accuracy--Cost Trade-offs of Quantum Algorithms for Non-Hermitian Transcorrelated Hamiltonians
Cheng-Lin Hong, Emiel Koridon, Paul K. Faehrmann +3
The electron--electron Coulomb singularity forces cusp structure in electronic wavefunctions. This cusp structure limits wavefunction regularity and slows the convergence of expans…
Learning Minimal Representations of Fermionic Ground States
Felix Frohnert, Emiel Koridon, Stefano Polla
We introduce an unsupervised machine-learning framework that discovers optimally compressed representations of quantum many-body ground states. Using an autoencoder neural network…
Ab Initio Polaritonic Chemistry on Diverse Quantum Computing Platforms: Qubit, Qudit, and Hybrid Qubit-Qumode Architectures
Even Chiari, Wafa Makhlouf, Lucie Pepe +5
Trying to export ab initio polaritonic chemistry onto emerging quantum computers raises fundamental questions. A central one is how to efficiently represent both fermionic and boso…
Learning Density Functionals from Noisy Quantum Data
Emiel Koridon, Felix Frohnert, Eric Prehn +3
The search for useful applications of noisy intermediate-scale quantum (NISQ) devices in quantum simulation has been hindered by their intrinsic noise and the high costs associated…
FragPT2: Multi-Fragment Wavefunction Embedding with Perturbative Interactions
Emiel Koridon, Souloke Sen, Lucas Visscher +1
Embedding techniques allow the efficient description of correlations within localized fragments of large molecular systems, while accounting for their environment at a lower level…
A hybrid quantum algorithm to detect conical intersections
Emiel Koridon, Joana Fraxanet, Alexandre Dauphin +3
Conical intersections are topologically protected crossings between the potential energy surfaces of a molecular Hamiltonian, known to play an important role in chemical processes…
Analytical nonadiabatic couplings and gradients within the state-averaged orbital-optimized variational quantum eigensolver
Saad Yalouz, Emiel Koridon, Bruno Senjean +3
In this work, we introduce several technical and analytical extensions to our recent state-averaged orbital-optimized variational quantum eigensolver (SA-OO-VQE) algorithm (see Ref…
Orbital transformations to reduce the 1-norm of the electronic structure Hamiltonian for quantum computing applications
Emiel Koridon, Saad Yalouz, Bruno Senjean +3
Reducing the complexity of quantum algorithms to treat quantum chemistry problems is essential to demonstrate an eventual quantum advantage of Noisy-Intermediate Scale Quantum (NIS…
