论文摘要
我们报告了具有抛物线偶联分布（也称为JX光子晶格）的光子晶格中非古典光的研究。我们专注于两个光子fock状态，两个光子N00N状态和单模式挤压状态以及连贯的状态作为晶格的输入。我们研究了平均光子数和量子状态从一个波导模式到另一个波导模式的完美传递的可能性。我们研究两个光子N00N状态的光子光子相关性。对于单模式挤压状态，我们详细研究，挤压因子的演变和波导模式之间的纠缠。我们的发现表明，所有情况下的平均光子数量的完美传递，并且仅在两个光子fock状态和两个光子N00N状态的情况下，量子状态的完美传递，而不是在挤压和连贯状态的情况下。我们的结果应在光子连续变量量子信息处理的物理实施中应用。
We report the study of non-classical light in a photonic lattice having parabolic coupling distribution, also known as Jx photonic lattice. We focus on two photon Fock state, two photon N00N state, and single mode squeezed state along with coherent state as input to the lattice. We investigate the possibility of perfect transfer of mean photon number as well as quantum state from one waveguide mode to other. We study photon-photon correlation for two photon N00N state. For single mode squeezed state we study in detail, the evolution of squeezing factor and entanglement between the waveguide modes. Our findings suggest perfect transfer of average photon number for all cases and perfect transfer of quantum state in case of two photon Fock state and two photon N00N state only and not in the case of squeezed and coherent state. Our results should have applications in physical implementation of photonic continuous variable quantum information processing.
