论文摘要
我们考虑将单个Qutrit用于随机生成。这是可能的，因为单QUTRIT具有上下文性特征。我们旨在优化生成序列的熵。为此，我们不依赖KCB的不平等，而是使用特定状态的使用和保真度检查。顺便说一句，我们表明该检查可以被视为应用于光子对或旋转1/2颗粒的CHSH不等式的变体（Qutrits通常被视为一对难以区分的量子）。该随机发电机的物理实现应通过仅实施旋转操作和测量所需的事实来减轻，而不是一般$ \ su（3）$ qutrit操纵。
We consider the use of a single qutrit for random generation. This is possible because single qutrits exhibit contextuality features. We aim to optimize the entropy of the generated sequence. To do this, we do not rely on the KCBS inequality but instead on the use of a specific state and a check for fidelity. By the way, we show that this check can be considered as a variant of the CHSH inequality applied to pairs of photons or spin-1/2 particles (qutrits are often realized as a pair of indistinguishable qubits). The physical realisation of this random generator should be eased by the fact it needs only to implement spin operations and measurement, not general $\SU(3)$ qutrit manipulations.
