Demonstration of quantum violation of realism

[ikkoham]

Abstract

Einstein, Podolsky, and Rosen (EPR) pointed out that quantum theory (QT) is not a "complete" theory[1]. Well-known Bell[2] and Clauser-Horne-Shimony-Holt[3] inequalities showed inconsistency between the local realism and QT, and Bell[4] and Kochen-Specker[5] discussed the inconsistency between noncontextual realism and QT.
In this project, our goal is a demonstration of such a violation on a quantum computer.

Description

There is a tutorial that introduces Bell-CHSH inequality.
Various methods are known for the violation of the local hidden variable model (e.g. Svetlichny's inequality, Mermin-Klyshko inequalities, or google "Bell-like inequalities"...).

On the other hand, for contextuality, the Bell-Kochen-Spaecker scenario cannot be tested directly.
Some noncontextual inequalities were proposed to verify contextuality in quantum theory [6, 7].

You can choose such inequality and implement a violation of it on a quantum computer.

Quantification of entanglement can be also a good project. For example, we compute some entanglement measure on a quantum computer. (if you are interested)
