A graphene based EPR entangler

纠缠EPR（Einstein-Podolsky-罗森）对的实现是实现量子计算和量子信息传输等量子应用的重要组成部分。虽然这已经在光子传输实验中证明了适合用于信息传送，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本地EPR纠缠的基础上注入分裂库珀对到石墨烯结构。 通过将铁磁检测引线纳入设备，我们不仅能够测量电荷相关性以证明电流从分裂的库珀对中流过，而且还可以测量慢电子的自旋，从而进行真正的量子纠缠测试。

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.
