Generation and estimation of symmetric states in quantum computersIn this work we address the problem of the generation and estimation of symmetric states in different architectures of quantum computers. We will discuss the results of the implementation of the methodology developed in [1,2,3] in processors from IonQ, Rigetti and Oxford Quantum Computing, as well as its possible applications to the problem of certification of quantum devices.[1] M.
