    "abstract": "We present a model of quantum teleportation protocol based on a double\nquantum dot array. The unknown qubit is encoded using a pair of quantum dots,\ncoupled by tunneling, with one excess electron. It is shown how to create\nmaximally entangled states with this kind of qubits using an adiabatically\nincreasing Coulomb repulsion between different pairs. This entangled states are\nexploited to perform teleportation again using an adiabatic coupling between\nthem and the incoming unknown state. Finally, a sudden separation of Bob\u0027s\nqubit enables a time evolution of Alice\u0027s state providing a modified version of\nstandard Bell measurement. Substituting the four quantum dots entangled state\nwith a chain of coupled DQD\u0027s, a quantum channel with high fidelity arises from\nthis scheme allowing the transmission over long distances.",
