    "abstract": "We show how to achieve perfect quantum state transfer and construct effective\ntwo-qubit gates between distant sites in engineered bosonic and fermionic\nnetworks. The Hamiltonian for the system can be determined by choosing an\neigenvalue spectrum satisfying a certain condition, which is shown to be both\nsufficient and necessary in mirror-symmetrical networks. The natures of the\neffective two-qubit gates depend on the exchange symmetry for fermions and\nbosons. For fermionic networks, the gates are entangling (and thus universal\nfor quantum computation). For bosonic networks, though the gates are not\nentangling, they allow two-way simultaneous communications. Protocols of\nentanglement generation in both bosonic and fermionic engineered networks are\ndiscussed.",
