Does testing of Bell or CHSH inequalities show that it is possible that quantum mechanics is local but violates the realism postulate?
Testing of Bell or CHSH (Clauser-Horne-Shimony-Holt) inequalities plays a crucial role in investigating the foundational principles of quantum mechanics, particularly concerning locality and realism. The violation of Bell or CHSH inequalities suggests that the predictions of quantum mechanics cannot be explained by local hidden variable theories, which adhere to both locality and realism. However, it
What are the loopholes that have been addressed in experiments testing the CHSH inequality, and why are they important to eliminate?
The CHSH inequality, named after its authors Clauser, Horne, Shimony, and Holt, is a fundamental concept in the field of quantum entanglement. It provides a means to test the violation of local realism, which is a key characteristic of quantum mechanics. In experiments testing the CHSH inequality, several loopholes have been identified and subsequently addressed
Describe the measurement outcomes of entangled qubits in the bit and sign bases and how they relate to the EPR paradox.
The measurement outcomes of entangled qubits in the bit and sign bases play a crucial role in understanding the EPR (Einstein-Podolsky-Rosen) paradox. The EPR paradox refers to a thought experiment proposed by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935, which highlighted the apparent conflict between quantum mechanics and classical physics. In this paradox,
