Two component Bose-Einstein condensates (BECs) have been recently shown to be viable systems for storing and manipulating quantum information. Unlike standard single-system qubits, the quantum information is duplicated in a large number of identical bosonic particles, thus can be considered to be a “macroscopic” qubit. One of the difficulties with such a system is how to effectively interact such qubits together in order to transfer quantum information and create entanglement. Here we discuss quantum state transfer using cavities containing two-component BECs coupled by optic fiber with a goal to apply this technique for quantum networking with BECs.
