    "abstract": "Preparing many body entangled states efficiently using available interactions\nis a challenging task. One solution may be to couple a system collectively with\na probe that leaves residual entanglement in the system. We investigate the\nentanglement produced between two possibly distant qubits 1 and 2 that interact\nlocally with a third qubit 3 under unitary evolution generated by pairwise\nHamiltonians. For the case where the Hamiltonians commute, relevant to certain\nquantum nondemolition measurements, the entanglement between qubits 1 and 2 is\ncalculated explicitly for several classes of initial states and compared with\nthe case of noncommuting interaction Hamiltonians. This analysis can be helpful\nto identify preferable physical system interactions for entangled state\nsynthesis.",
