We present basics of mixed-state entanglement theory. The first part of the article is devoted to mathematical characterizations of entangled states. In second part we discuss the question of using mixed-state entanglement for quantum communication. In particular, a type of entanglement that is not directly useful for quantum communcation (called bound entanglement) is analysed in detail.

Discussion (0). Continue with ORCID to comment.

  1. Distribution Relationship of Quantum Battery Capacity

    quant-ph 2025-02 conditional novelty 5.0 of 10

    For X-states, quantum battery capacity obeys a monogamy inequality, and the leftover capacity can be redistributed to subsystems by a global unitary.
