Strictly localized orbitals from spatial partitioning with the discontinuous Galerkin method
César Feniou, César Feniou, Julien Toulouse
We present a rigorous electronic-structure theory of strictly localized orbitals associated with a spatial partition of the one-electron Hilbert space that remains well defined in…
The Convergence Frontier: Integrating Machine Learning and High Performance Quantum Computing for Next-Generation Drug Discovery
Narjes Ansari, César Feniou, Nicolaï Gouraud +13
Integrating quantum mechanics into drug discovery marks a decisive shift from empirical trial-and-error toward quantitative precision. However, the prohibitive cost of ab initio mo…
High Performance Quantum Emulation for Chemistry Applications with Hyperion
Olivier Adjoua, Siwar Badreddine, César Feniou +4
The strategic demand for quantum hardware currently outpaces the availability of near-term devices, necessitating high-performance software emulators to validate novel protocols. W…
Logarithmic-depth quantum state preparation of polynomials
Baptiste Claudon, Alexis Lucas, Jean-Philip Piquemal +2
Quantum state preparation is a central primitive in many quantum algorithms, yet it is generally resource intensive, with efficient constructions known only for structured families…
An Optimized Construction of Lie Algebra Generator Pools for Variational Quantum Eigensolvers in Chemistry
Yaromir Viswanathan, Olivier Adjoua, César Feniou +2
Lie algebras are essential mathematical structures used in physics to describe sets of quantum operators. Identifying a minimal set of generators to construct these algebras is a c…
Real-Space Chemistry on Quantum Computers: A Fault-Tolerant Algorithm with Adaptive Grids and Transcorrelated Extension
César Feniou, Christopher Cherfan, Julien Zylberman +3
First-quantized, real-space formulations of quantum chemistry on quantum computers are appealing: qubit count scales logarithmically with spatial resolution, and Coulomb operators…
