AI 中文摘要
我们提出了一种最小量子光学方案，用于在半导体量子盘中产生光子偏振与电子轨道角动量之间的混合纠缠。自旋 - 轨道结构的双光子态激发同一盘中的两个通道：辐射复合的零轨道角动量通道和存储电子轨道量子比特的有限轨道角动量通道。有效的相干映射制备选定的双激发态，随后发射一个光子，其偏振与剩余电子轨道态纠缠。主方程分析表明，在选定输出模式的单光子占据条件下的预示态在理想相干极限下接近目标纠缠态。我们还讨论了轨道弛豫以及与分支相关的库仑位移、轨道角动量混合和有限轨道角动量辐射泄漏的微扰有效性条件。这个原理验证有效模型为半导体纳米结构中结构化光介导的光子 - 电子混合纠缠提供了一条途径。
英文摘要
We propose a minimal quantum-optical scheme for generating hybrid entanglement between photon polarization and electronic orbital angular momentum in a semiconductor quantum disk. A spin--orbit structured two-photon state excites two channels in the same disk: a radiatively recombining zero-orbital-angular-momentum channel and a finite-orbital-angular-momentum channel that stores the electronic orbital qubit. An effective coherent mapping prepares a selected two-excitation state, followed by emission of a photon whose polarization is entangled with the residual electronic orbital state. A master-equation analysis shows that the heralded state conditioned on single-photon occupation of the selected output mode approaches the target entangled state in the ideal coherent limit. We also discuss orbital relaxation and perturbative validity conditions for branch-dependent Coulomb shifts, orbital-angular-momentum mixing, and finite-orbital-angular-momentum radiative leakage. This proof-of-principle effective model suggests a route toward structured-light-mediated photon--electron hybrid entanglement in semiconductor nanostructures.
