  • Quantum Entanglement

    Introduction Quantum entanglement is a quantum mechanical phenomenon in which two or more particles become linked and instantaneously affect each other’s state no matter how far apart they are. This entanglement is a fundamental aspect of quantum mechanics, with broad implications in areas such as quantum computing, quantum cryptography, and quantum teleportation. Basics of Quantum…

  • CHSH Inequality Test

    Introduction The CHSH inequality, named after John Clauser, Michael Horne, Abner Shimony, and Richard Holt, is a specific case of Bell’s inequalities and is used to test whether the predictions of quantum mechanics about entangled particles are borne out by experiment, or whether local hidden variable theories can be sustained. Bell’s Theorem and Local Hidden…

  • Bell’s Theorem

    Introduction Bell’s theorem, proposed by physicist John Bell in 1964, is a pivotal result in quantum mechanics. It deals with the concept of local realism, a principle stating that physical processes occurring at one location do not depend on the properties of objects at other locations. Statement of Bell’s Theorem Bell’s theorem states that: “No…
