In statistics, Bayesian techniques are known to be good candidates for the optimization of functions that are hard to evaluate and, at the same time they are known to show a reduction in the total number of measurements required, as compared to non-adaptive methods.  
We develop such technique for problems whose solution can be encoded in a cost quantum Hamiltonian of which one wants to find the ground state via a parameter-dependent evolution, such as  the Quantum Approximate Optimization Algorithm (QAOA) as applied for example to MaxCut or other combinatorial problems. 
Our central focus is the implementation of such a Bayesian adaptive protocol on a NISQ device,  more specifically on the PASQAL platform.
