Kochen-Specker定理的13条射线状态无关证明

State-independent proof of Kochen-Specker theorem with 13 rays

Sixia Yu, C. H. Oh

摘要:

量子语境性,正如Kochen和Specker以及Bell所证明的那样,应该在任何具有两个以上可区分状态的系统中的任何状态中表现出来,并且最近已经在各种物理系统上得到了实验验证。然而,对于最简单的系统,能够表现出的上下文,quutrit,量子上下文验证只有状态依赖的实验中,因为太多(至少31)的可观测量涉及在所有已知的状态无关的测试。在这里,我们报告了一个实验可检验的不等式,只涉及13个观测值,满足所有非上下文的现实模型,而被违反的所有quutrit状态。因此,我们的不等式实际上将促进一个不可分的量子系统的量子上下文的状态无关的测试。我们还提供了一个破纪录的状态独立的证明Kochen-Specker定理与13个方向确定的26个点的表面上的3 × 3魔方。

英文摘要:

Quantum contextuality, as proved by Kochen and Specker, and also by Bell, should manifest itself in any state in any system with more than two distinguishable states and recently has been experimentally verified on various physical systems. However for the simplest system capable of exhibiting contextuality, a qutrit, the quantum contextuality is verified only state-dependently in experiment because too many (at least 31) observables are involved in all the known state-independent tests. Here we report an experimentally testable inequality involving only 13 observables that is satisfied by all non-contextual realistic models while being violated by all qutrit states. Thus our inequality will practically facilitate a state-independent test of the quantum contextuality for an indivisible quantum system. We provide also a record-breaking state-independent proof of the Kochen-Specker theorem with 13 directions determined by 26 points on the surface of a three by three magic cube.
