We present a review of the problem of finding out whether a quantum state of two or more parties is entangled or separable. After a formal definition of entangled states, we present a few criteria for identifying entangled states and introduce some entanglement measures. We also provide a classification of entangled states with respect to their usefulness in quantum dense coding, and present some aspects of multipartite entanglement.

    quant-ph 2025-01 unverdicted novelty 5.0

    In this global-measurement Ising protocol the apparent measurement-induced transition at finite τ_c for L≈26-28 recedes to τ_c=0 in the large-L limit with scaling τ_c∼1/√L.
