Digital quantum simulation of real time dynamics of Yukawa coupling

A mapping from Fock space boson states to qubits is given and an underlying digital quantum simulation algorithm of bosons is derived. We realize the algorithm in MPS (matrix product state) which simulating real time dynamics of Yukawa coupling in varies initial states and coupling constants. This proposal may be achieved in superconductivity NISQ (noisy intermediate-scale quantum) computer not far future.
