Simulating the dynamics of time-dependent Hamiltonians with a truncated Dyson series
Simulating the dynamics of time-dependent Hamiltonians with a truncated Dyson series
We provide a general method for efficiently simulating time-dependent Hamiltonian dynamics on a circuit-model based quantum computer. Our approach is based on approximating the truncated Dyson series of the evolution operator, extending the earlier proposal by Berry to evolution generated by explicitly time-dependent Hamiltonians. Two alternative strategies are proposed to …
