In one of the largest quantum simulations ever performed, up to 53 trapped ion qubits have been used to simulate properties of many body magnetic interactions. The qubits are each prepared with individual control, and measured in a single shot with nearly 100% efficiency. This allows the observation of arbitrary correlation functions that cannot be calculated. This restricted quantum computer becomes fully programmable and reconfigurable with straightforward modifications in the control lasers.
