Variational dynamics as a ground-state problem on a quantum computer
We propose a variational quantum algorithm to study the real-time dynamics of quantum systems as a ground-state problem. The method is based on the original proposal of Feynman and Kitaev to encode time into a register of auxiliary qubits. We prepare the Feynman-Kitaev Hamiltonian acting on the comp...
