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…

Quantum Speedup for Nonreversible Markov Chains
Baptiste Claudon, Jean-Philip Piquemal, Pierre Monmarché
Quantum algorithms can potentially solve a handful of problems more efficiently than their classical counterparts. In that context, it has been discussed that Markov chains problem…

A simple algorithm to reflect through eigenspaces of unitaries
Baptiste Claudon
Reflections are omnipresent tools in quantum algorithms. We consider the task of reflecting through the eigenspace of an implementable unitary. Such reflections are generally desig…
