Quantum implementation of an artificial feed-forward neural network
Francesco Tacchino, Panagiotis Barkoutsos, Chiara Macchiavello +3
Artificial intelligence algorithms largely build on multi-layered neural networks. Coping with their increasing complexity and memory requirements calls for a paradigmatic change i…
Quantum Orbital-Optimized Unitary Coupled Cluster Methods in the Strongly Correlated Regime: Can Quantum Algorithms Outperform their Classical Equivalents?
Igor O. Sokolov, Panagiotis Kl. Barkoutsos, Pauline J. Ollitrault +4
The Coupled Cluster (CC) method is used to compute the electronic correlation energy in atoms and molecules and often leads to highly accurate results. However, due to its single-r…
Non-unitary operations for ground-state calculations in near term quantum computers
Guglielmo Mazzola, Pauline Ollitrault, Panagiotis Barkoutsos +1
We introduce a quantum Monte Carlo inspired reweighting scheme to accurately compute energies from optimally short quantum circuits. This effectively hybrid quantum-classical appro…
Quantum equation of motion for computing molecular excitation energies on a noisy quantum processor
Pauline J Ollitrault, Abhinav Kandala, Chun-Fu Chen +7
The computation of molecular excitation energies is essential for predicting photo-induced reactions of chemical and technological interest. While the classical computing resources…
Variational Quantum Simulation of Ultrastrong Light-Matter Coupling
Agustin Di Paolo, Panagiotis Kl. Barkoutsos, Ivano Tavernelli +1
We propose the simulation of quantum-optical systems in the ultrastrong-coupling regime using a variational quantum algorithm. More precisely, we introduce a short-depth variationa…
Resource-Efficient Quantum Algorithm for Protein Folding
Anton Robert, Panagiotis Kl. Barkoutsos, Stefan Woerner +1
Predicting the three-dimensional (3D) structure of a protein from its primary sequence of amino acids is known as the protein folding (PF) problem. Due to the central role of prote…
