Quantum circuits for strongly correlated quantum systems
... In this paper we propose to use a quantum computer in a different way, such that we not only have access to the lowenergy states but to the whole spectrum for certain quantum many-body problems. This allows us to prepare any excited state or thermal state at any temperature, as well as the dynamical ...
