【 摘 要 】

The development of a working quantum computer utilizing electron-spin states as qubits is a major goal for many theorists and experimentalists. The future applications of quantum information technology would also require a reliable method for the transportation of information between different parts of the system. One such promising method is the propagation of electrons by a surface acoustic wave (SAW). In this paper, we simulate the SAW transfer of two interacting electrons through a Y-shaped junction. Our results show that the singlet and triplet states can be differentiated in the Y junction by an electrostatic detuning potential, an effect that could be used in, for example, measuring the state of a two-spin qubit.
