摘要

弱超细相互作用和自旋轨道相互作用使得石墨烯量子点量子比特材料优于其他半导体量子比特材料。所以;本文提出了基于石墨烯纳米带被氢原子功能化的石墨烯纳米带双量子点量子比特的哈密顿模型,并在量子计算机上进行了理论研究。我们使用狄拉克方程和海森堡交换法来求解我们的模型。然后我们确定交换交互作用Jex。我们研究了势垒高度和势垒厚度d对交换耦合Jex的影响。我们的结果表明,Jex的变化很大程度上取决于这些参数,以及这些参数在特定值时对Jex的影响。此外,我们可以使用势垒高度和势垒厚度d的变化来表示信息的传输方式,这对量子信息所需的门操作很重要。

Double quantum dot of graphene nanoribbon qubit for Quantum information
Weak hyperfine interaction as well as spin-orbit interaction enforced that graphene quantum dot qubit material rather than other semiconductor qubits material. So; we suggest here a Hamiltonian model of a graphene nanoribbon double quantum dot qubit based on the functionalization of graphene nanoribbon by hydrogen atoms to produce a theoretical studied on a quantum computer. We are using the Dirac equation and the Heisenberg exchange approach to solve our model. Then we determine the exchange interaction Jex. We investigate the effects of potential barrier height and barrier thickness d on exchange coupling Jex. Our results show a great variation of Jex depends on these parameters, and how this parameter affected on Jex at special value. Also, we can use the variation of Jex with both potential barrier height and barrier thickness d to represent how the information can transfer, which is important to gate operation necessary for quantum information.
