Hardware-efficient protocol for measuring complex Loschmidt echoes in a Fermi-Hubbard optical-lattice processor via quench dynamics and tailored imaginary-time pulses.
IV we describe how the unitaryV implementing the (normalized) ITE exp( −HΛϑ), with HΛ =P m Hm can be decomposed into local unitaries Vm as defined in Eq
