Quantum teleportation in triangular triple quantum dots
摘要
Quantum teleportation enables the rapid transmission of quantum states. In this paper, we propose a quantum teleportation scheme using triangular triple quantum dots (TTQD). We demonstrate one-qubit teleportation within a triple quantum dot system. The teleportation process involves a series of quantum gates and rotation operations. The primary focus of this work is to control single-qubit gates by applying magnetic fields, while multi-qubit gates are realized through spin coupling between quantum dots and rotation operations. The process is then fine-tuned using single-qubit gates based on the results of projection measurements, enabling the realization of teleportation in triangular triple quantum dots. Due to the geometric symmetry of the TTQD structure, it can lead to more stable. Moreover, in TTQD systems, the time required to complete the quantum teleportation process is significantly reduced by leveraging magnetic fields.
