Geometry and quantum physics in the design of an electronic device

The article considers a scientific problem in quantum mechanics related to geometry. The famous German mathematician Mobius A.F. has opened a new page in geometry — one-sided surfaces. The first of these surfaces was named after him: a ribbon (or sheet) Mobius. Almost simultaneously with Mobius, another German mathematician, Listing I., discovered this surface. Later, other one-sided surfaces were discovered. However, it turned out that they are a modification of the Mobius sheet. An example is given of how a modern engineer solved a technical problem in an electronic device by accidentally recalling a Mobius tape. Physicists are still trying to scientifically explain the positive effect in the operation of this electronic device. The observed physical phenomenon is called the Einstein-Podolsky-Rosen paradox
