相互作用固态发射体确定性产生大规模纠缠光子团簇态

Mercedes Gimeno-Segovia, Terry Rudolph, Sophia E. Economou

摘要:

创造大的高度纠缠的“簇”态的能力对于基于测量的量子计算是至关重要的。我们发现,确定性的多光子纠缠可以从耦合的固态量子发射器创建,而不需要任何两个量子比特门,无论发射器是否相同。特别是,我们提出了一个通用的方法,通过直接使用的始终在线的交换相互作用,结合单量子比特操作的控制纠缠创建。这是用来提供一个配方,用于产生二维,集群状态纠缠光子,可以进行与现有的实验能力在量子点。

英文摘要:

The ability to create large highly entangled `cluster' states is crucial for measurement-based quantum computing. We show that deterministic multi-photon entanglement can be created from coupled solid state quantum emitters without the need for any two-qubit gates and regardless of whether the emitters are identical. In particular, we present a general method for controlled entanglement creation by making direct use of the always-on exchange interaction, in combination with single-qubit operations. This is used to provide a recipe for the generation of two-dimensional, cluster-state entangled photons that can be carried out with existing experimental capabilities in quantum dots.
