In this work, we show that the well-known Bell test calledClauser-Horne-Shimony-Holt (CHSH) does not only exhibit non-local correlationsbut also contextual ones. For this purpose, we investigate the symmetricsubgroup of two-qubit states corresponding to qutrit states (three-levelquantum states), which exhibit the KCBS-type (non-)contextuality. Later, weapply the CHSH test to them and find a new non-contextuality bound for thistest. This shows us that the CHSH inequality can be modified by changing thelimit to use it as a contextuality test. Also, the number of measurementsrequired is four, less than the number of measurements in the KCBS test (Thatis five).

The CHSH Test is Sufficient to Observe Quantum Contextuality
