Abstract
Hybrid classical-quantum protocols for quantum simulations on NISQ platforms. The project focuses on hybrid classical-quantum protocols devised for quantum simulations, and it is structured to navigate through two different but intertwined dimensions: i) numerical algorithms and related methodological issues, ii) physical description and control of many body Hamiltonians, while keeping in mind and exploiting available quantum devices. In particular, we plan to utilize the quantum annealer technology of D-Wave and the Rydberg atom platform developed by Pasqal. Expected results: • Development of hybrid protocols for some relevant Physical Models, such as: 1a. Random spin models; 1b. Long range spin Hamiltonians; 1c. Finite group lattice gauge theories. • Applications of hybrid protocols to Numerical Methods, such as: 2a. Bayesian inference or machine learning approaches for VQA; 2b. Interpolation techniques for smoothness of parameters in optimization schemes; 2c. Quantum annealing or Rydberg atom platform for projective QMC techniques. • Hybrid protocols for Quantum control and dynamics, such as: 3a. Adiabaticity in QAOA/VQA protocols in quantum Ising Hamiltonians as in quantum annealers and Rydberg atom platforms; 3b. Hybrid protocols for the evaluation of time-dependent observables and correlations in simple few-body systems; 3c. TDDFT framework for quantum spin models beyond regimes accessible via unbiased algorithms.
