论文摘要
多粒子纠缠对量子计量学和量子信息处理具有重要意义。我们在这里提出了一个有效的方案，以在固态设置中生成稳定的多粒子纠缠，其中将一系列硅离散中心嵌入准二维的声学钻石波导中。在此方案中，声子模式的连续体诱导SIV中心之间可控的耗散耦合。我们表明，通过适当选择SIV中心之间的距离，可以由于破坏性干扰而关闭偶极 - 偶极相互作用，从而实现了DICKE超平稳型模型。这引起了具有高保真度的SIV中心的纠缠稳定状态。该协议为在固态系统中生成多粒纠缠提供了可行的设置。
Multiparticle entanglement is of great significance for quantum metrology and quantum information processing. We here present an efficient scheme to generate stable multiparticle entanglement in a solid state setup, where an array of silicon-vacancy centers are embedded in a quasi-one-dimensional acoustic diamond waveguide. In this scheme, the continuum of phonon modes induces a controllable dissipative coupling among the SiV centers. We show that, by an appropriate choice of the distance between the SiV centers, the dipole-dipole interactions can be switched off due to destructive interferences, thus realizing a Dicke superradiance model. This gives rise to an entangled steady state of SiV centers with high fidelities. The protocol provides a feasible setup for the generation of multiparticle entanglement in a solid state system.
