20.500.12556/RUL-171584 Variational ground-state quantum adiabatic theorem We present a variational quantum adiabatic theorem, which states that, under certain assumptions, the adiabatic dynamics projected onto a variational manifold follow the instantaneous variational ground state. We focus on low-entanglement variational manifolds and target Hamiltonians with classical ground states. Despite highly entangled intermediate states along the exact adiabatic path, the variational evolution converges to the target ground state. We demonstrate this approach with several examples that align with our theoretical analysis. adiabatic quantum optimization quantum algorithms quantum algorithms and computation adiabatic approximation variational approach adiabatna kvantna optimizacija kvantni algoritmi kvantni algoritmi in računanje adiabatska aproksimacija variacijski pristop true false true Angleški jezik Slovenski jezik Članek v reviji 2025-08-28 11:58:32 2025-08-28 11:58:33 2025-09-08 03:35:13 0000-00-00 00:00:00 2025 0 0 Str. 1-9 iss. 13, art. 130601 Vol. 134 Mar. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004 0031-9007 10.1103/PhysRevLett.134.130601 230918403 PhysRevLett.134.130601.pdf PhysRevLett.134.130601.pdf 1 4C9E14FB77E7DA384B73749788678C39 ac74b4a219da9c299b743a41d7ba8b12915a45345173ec9605108658ee4a46d6 2fc980d3-83f6-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214957 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.134.130601 1 6e265e23-83f5-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214956 Fakulteta za računalništvo in informatiko 0 0 0
