Quantum entanglement is a complex topic where two particles' states cannot be expressed as independent product states, with Bell states being a key example. Recommended resources for understanding this concept include Valerio Scarani's paper on quantum information and the mathematics of entanglement by Brandao et al. For a more accessible introduction, the Physics Today article is suggested, along with Asher Peres' book "Quantum Theory: Concepts and Methods." These materials cater to undergraduate students seeking a deeper understanding of quantum entanglement. Engaging with these resources can enhance comprehension of this fundamental phenomenon in quantum physics.
