A graphene based EPR entangler

量子计算和信息的量子隐形传态等许多量子应用的实现都需要实现纠缠态EPR （Einstein-Podolsky-Rosen）对。虽然这已经在适合用于信息传送的光子传输实验中得到了证明，但在固态中的演示将是计算应用的飞跃。在这个项目中，我们的目标是建立一个基于石墨烯的非局部EPR纠缠体，该纠缠体是基于在石墨烯结构中注入分裂库珀对的。通过将铁磁探测引线整合到设备中，我们不仅可以测量电荷相关性来证明分裂库珀对的电流流动，还可以测量减速电子的自旋，从而对真正的量子纠缠进行测试。

An important ingredient for the realization of many quantum applications, such as quantum computing and quantum teleportation of information, is the achievement of entangled EPR (Einstein-Podolsky-Rosen) pairs. While this has been demonstrated in photon transmission experiments appropriate for use in information teleportation, a demonstration in the solid state would be a leap forward for computing applications. In this project, we aim to build a graphene based non-local EPR entangler based on injection a split Cooper pair into the graphene structure. By incorporating ferromagnetic detection leads into the device, we will be able to not only measure the charge correlation to prove the current flows from split Cooper pairs, but also measure the spin of the slowing electrons and therefore perform a test for true quantum entanglement.
