用qutrit的自旋随机生成

Random generation with the spin of a qutrit

François ARNAULT, Don ANOMAN

摘要:

我们考虑使用一个单一的quutrit随机生成。这是可能的,因为单个qutrits表现出语境特征。我们的目标是优化生成的序列的熵。要做到这一点,我们不依赖于KCBS不等式,而是使用特定的状态和保真度检查。顺便说一下,我们证明了这种检查可以被认为是应用于光子对或自旋1/2粒子(qutrits通常被实现为一对不可区分的qubit)的CHSH不等式的变体。这种随机发生器的物理实现应该是容易的,因为它只需要实现自旋操作和测量,而不是一般的$\SU(3)$ quutrit操作。

英文摘要:

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.
