Quantum Computing for Polaritonic Chemistry
In quantum computing, the simulation of many-body systems is one of the most promising applications of emerging quantum platforms. While significant progress has been made in developing near-term quantum algorithms for purely fermionic systems—particularly in quantum chemistry—an important gap remains: extending beyond the « bare » electronic structure to include interactions with external environments. This challenge is especially relevant in hybrid fermion-boson systems, where electronic states couple to external bosonic fields, such as photons.
Accurately describing these systems requires capturing entanglement between fermions and bosons, posing a major theoretical challenge and a compelling target for quantum computing. In this presentation, I will discuss recent efforts at the Laboratoire de Chimie Quantique Strasbourg to address this issue. Focusing on Polaritonic Quantum Chemistry, I will outline how we are developing near-term quantum algorithms to accurately describe both ground and excited states of molecules in optical cavities.
