Trapped atomic ion crystals are a leading platform for quantum simulations of spin systems, with programmable and long-range spin-spin interactions mediated by excitations of phonons in the crystal. We describe a complementary approach for quantum simulations of bosonic systems using phonons in trapped-ion crystals, here mediated by excitations of the trapped ion spins. The scheme features a high degree of programability over a dense graph of bosonic couplings and is suitable for hard problems such as boson sampling and simulations of long range bosonic and spin-boson Hamiltonians.
