Simulating Bell inequalities with Qibo

Abstract

Abstract We present educational material about Bell inequalities in the context of quantum computing. In particular, we provide software tools to simulate their violation, together with a guide for classroom discussion. The material is organized in three modules of increasing difficulty, and the relative implementation has been written in Qibo, an open-source software suite to simulate quantum circuits with the ability to interface with quantum hardware. The topic of inequalities allows us to not only introduce undergraduate or graduate students to crucial theoretical issues in quantum mechanics, such as entanglement, correlations, hidden variables and non-locality, but also to practically put hands on tools to implement a real simulation, where statistical aspects and noise coming from current quantum chips also come into play.
