Are Molecules Magical? Non-Stabilizerness in Molecular Bonding
Matthieu Sarkis, Alexandre Tkatchenko
Isolated atoms as well as molecules at equilibrium are presumed to be simple from the point of view of quantum computational complexity. Here we show that the process of chemical b…
Magic Steady State Production: Non-Hermitian, Dissipative, and Stochastic Pathways
Pablo Martinez-Azcona, Matthieu Sarkis, Alexandre Tkatchenko +1
Universal quantum computers require entanglement and non-stabilizerness, a resource known as \textit{quantum magic}. Here, we introduce a protocol that prepares magic steady states…
Star Topology Optimizes the Charging Power of Quantum Batteries
Matthieu Sarkis, Oskar A. ProÅniak, Samuel Nigro +1
Quantum batteries are quantum systems that store energy and deliver it on demand, and their practical value hinges on how fast they can be charged. While collective charging protoc…
Multipartite Non-local Magic and SYK Model
Vinay Malvimat, Matthieu Sarkis, Yena Suk +1
We investigate the structure of quantum magic in interacting disordered fermionic systems, quantifying non-stabilizerness via the fermionic stabilizer Rényi entropy (SRE). To reso…
Magic for Hybrid Boson-Fermion Systems: A Grassmann Phase-Space Approach
Matthieu Sarkis, Pablo Martinez-Azcona, Alexandre Tkatchenko
Non-stabilizerness enables universality beyond Gaussian/Clifford dynamics, yet no resource theory exists for systems combining bosonic and fermionic degrees of freedom. Using the G…
