Operational connection between predictability and entanglement in entanglement swapping from partially entangled pure states [PDF]
Physics Letters, Section A: General, Atomic and Solid State Physics, 2022 Complementarity and entanglement are fundamental features of Quantum Mechanics that were recently related in triality equalities that involve quantum coherence, the wave aspect of a qubit, and quantum predictability and quantum entanglement, the particle

Switching and Swapping of Quantum Information: Entropy and Entanglement Level
Entropy, 2021 Information switching and swapping seem to be fundamental elements of quantum communication protocols. Another crucial issue is the presence of entanglement and its level in inspected quantum systems. In this article, a formal definition of the operation

Experimental Diagnostics of Entanglement Swapping by a Collective Entanglement Test [PDF]
Physical Review Applied, 2020 The paper reports on experimental diagnostics of entanglement swapping protocol by means of collective entanglement witness. Our approach is suitable to detect disturbances occurring in the preparation of quantum states, quantum communication channel and imperfect Bell-state projection.

Entanglement Swapping and Quantum Correlations via Symmetric Joint Measurements. [PDF]
Physical Review Letters, 2022 We use hyperentanglement to experimentally realize deterministic entanglement swapping based on quantum elegant joint measurements. These are joint projections of two qubits onto highly symmetric, isoentangled bases.

Quantum Entanglement Swapping between Two Multipartite Entangled States [PDF]
Physical Review Letters, 2016 Quantum entanglement swapping is one of the most promising ways to realize the quantum connection among local quantum nodes. In this Letter, we present an experimental demonstration of the entanglement swapping between two independent multipartite entangled states, each of which involves a tripartite Greenberger-Horne-Zeilinger (GHZ) entangled state of

Entanglement swapping of two arbitrarily degraded entangled states
Physical Review A, 2016 We consider entanglement swapping, a key component of quantum network operations and entanglement distribution. Pure entangled states, which are the desired input to the swapping protocol, are typically mixed by environmental interactions causing a reduction in their degree of entanglement.

Activation of entanglement in generalized entanglement swapping [PDF]
Physical Review AWe study entanglement activation in a generalized entanglement swapping process involving two Bell pairs and generalized measurements. The conventional understanding posits entangled measurements as both necessary and sufficient for establishing entanglement between distant parties.
