@article{Lewenstein2019QuantumE, title={Quantum Entanglement}, author={Maciej Lewenstein}, journal={Do We Really Understand Quantum Mechanics?}, year={2019} }

Entanglement is a fundamental resource in quantum information theory. It allows performing new kinds of communication, such as quantum teleportation and quantum dense coding. It is an essential ingredient in some quantum cryptographic protocols and in quantum algorithms. We give a brief overview of the concept of entanglement in quantum mechanics, and discuss the major results and open problems related to the recent scientific progress in this field.
