论文摘要
我们通过利用属于独特的空间光学模式的联合传播光子的刺激的模式间brillouin散射来探讨纳米级电线中光子孔纠缠状态的可能性。在纳米线内部，由于辐射压力，光子 - 音波偶联显着增强。 Stokes和Anti-Stokes过程被解耦，因为它们涉及导致对称性破坏的不同声子模式，这是由于不同的相匹配要求而导致的。对于Stokes工艺，在存在经典泵场的情况下，光子 - 音波对被歼灭或创建，对于反stokes过程，我们获得了光子和声子之间的相干振荡。纠缠状态的外观可以扩展使用纳米线的使用，例如硅制成的纳米线，涉及涉及光子和声子的量子信息处理，这些信息可以轻松地集成到片上网络中。
We explore the possibility of the formation of photon-phonon entangled states in nanoscale wires by exploiting stimulated inter-modal Brillouin scattering of co-propagating photons that belong to distinct spatial optical modes. Inside nanowires, the photon-phonon coupling is significantly enhanced owing to radiation pressure. The Stokes and anti-Stokes processes are decoupled as they involve different phonon modes that lead to symmetry breaking, which results from different phase-matching requirements. For the Stokes process photon-phonon pairs are annihilated or created, in the presence of a classical pump field, and for the anti-Stokes process we obtain coherent oscillations between photons and phonons. The appearance of entangled states can extend the use of nanowires, for example, those made of silicon, into quantum information processing involving photons and phonons in a setup that can be easily integrated into an on-chip network.
