Entanglement 25 Years after Quantum Teleportation: Testing Joint Measurements in Quantum Networks [PDF]
Entropy, 2019 Twenty-five years after the invention of quantum teleportation, the concept of entanglement gained enormous popularity. This is especially nice to those who remember that entanglement was not even taught at universities until the 1990s.

Overcoming noise in quantum teleportation with multipartite hybrid entanglement. [PDF]
Sci Adv, 2022 Quantum entanglement and decoherence are the two counterforces of many quantum technologies and protocols. For example, while quantum teleportation is fueled by a pair of maximally entangled resource qubits, it is vulnerable to decoherence.
