However\, the exponential scaling of the basis size wi th the number of degrees of freedom hampers a direct numerical solution fo r heavy nuclei. In this talk\, I present a quantum annealing protocol to o btain nuclear ground states. I propose a tailored driver Hamiltonian that preserves a large gap and validate our approach in a dozen nuclei with bas is sizes up to 10^5 using classical simulations of the annealing evolution . I show the relation between the spectral gap and the total time of the a nnealing protocol\, assessing its accuracy by comparing the fidelity and e nergy relative error to classical benchmarks. While the nuclear Hamiltonia n is non-local and thus challenging to implement in current setups\, the e stimated computational cost of our annealing protocol on quantum circuits is polynomial in the many-body basis size\, paving the way to study heavie r nuclei.\n LOCATION:https://researchseminars.org/talk/TalentQ/20/ END:VEVENT END:VCALENDAR
