Запутанность на простейших примерах

Entanglement isn't just for spin: https://arxiv.org/abs/1703.10620

Quantum entanglement occurs not just in discrete systems such as spins, but also in the spatial wave functions of systems with more than one degree of freedom. It is easy to introduce students to entangled wave functions at an early stage, in any course that discusses wave functions. Doing so not only prepares students to learn about Bell's theorem and quantum information science, but can also provide a deeper understanding of the principles of quantum mechanics and help fight against some common misconceptions. Here I introduce several pictorial examples of entangled wave functions that depend on just two spatial variables. I also show how such wave functions can arise dynamically, and describe how to quantify their entanglement.

С примерами недопонимания простых вещей, возникающего у тех, кто только начинает изучать квантовую механику. Эта статья направлена в Am.J.Phys., очень клевый журнальчик учебно-методического направления, уже не раз я находил там что-то полезное для работы.
