New : Overlap-ADAPT-VQE: Practical Quantum Chemistry on Quantum Computers via Overlap-Guided Compact Ansätze. Great work by ( & M. Hassan; nice theochem/maths interdiscipl. collab. with Y. Maday


2/ By avoiding building the ansatz in the energy landscape strewn with local minima, the Overlap-ADAPT-VQE produces ultra-compact ansätze suitable for high-accuracy initializations of a new ADAPT procedure resulting in massive savings in circuit depth

3/ The Overlap-ADAPT-VQE can be used as a compression strategy for ADAPT but can also be initialized with accurate Selected-Configuration Interaction classical target wave-functions paving the way for chemically accurate simulations of larger systems.
