论文摘要
展示了用于光学横向空间模式上的高维线性量子操作的简单灵活的方案。通过对称信息完全正面运算符值（SIC POVM）的对称信息的量子傅立叶变换（QFT）和量子状态层析成像（QST）以15的尺寸实现。QFT的矩阵保真度为0.85，而SIC POVMS和QST的统计保真度为QST和QST的统计，QST和fidelity qst and QST的忠诚度为〜0.97和0.97和0.853。我们认为，我们的设备具有进一步探索非线性晶体中自发参数降低转换提供的高维空间纠缠的潜力。
A simple and flexible scheme for high-dimensional linear quantum operations on optical transverse spatial modes is demonstrated. The quantum Fourier transformation (QFT) and quantum state tomography (QST) via symmetric informationally complete positive operator-valued measures (SIC POVMs) are implemented with dimensionality of 15. The matrix fidelity of QFT is 0.85, while the statistical fidelity of SIC POVMs and fidelity of QST are ~0.97 and up to 0.853, respectively. We believe that our device has the potential for further exploration of high-dimensional spatial entanglement provided by spontaneous parametric down conversion in nonlinear crystals.
