Exact rate analysis for quantum repeaters with imperfect memories and entanglement swapping as soon as possible [PDF]
Physical Review Research, 2022 We present an exact rate analysis for a secret key that can be shared among two parties employing a linear quantum repeater chain. One of our main motivations is to address the question whether simply placing quantum memories along a quantum ...

Continuous Variable Entanglement Swapping [PDF]
Physical Review Letters, 1999 Summary: We investigate the efficacy with which polarization entanglement can be teleported using a continuous measurement scheme. We show that by using the correct gain for the classical channel the degree of violation of locality that can be demonstrated (using a CH-type inequality) is not a function of the level of entanglement squeezing used in the

Multiparticle generalization of entanglement swapping [PDF]
Physical Review A, 1998 We generalize the procedure of entanglement swapping to obtain a scheme for manipulating entanglement in multiparticle systems. We describe how this scheme allows to establish multiparticle entanglement between particles belonging to distant users in a communication network through a prior distribution of singlets followed by only local measurements ...

Relativistic entanglement of single and two particle systems [PDF]
, 2013 One of the defining features of quantum theory is entanglement, the notion that quantum systems can display correlations that are impossible from the classical point of view.

Quantum dialogue without information leakage based on the entanglement swapping between any two Bell states and the shared secret Bell state [PDF]
, 2022 In order to avoid the risk of information leakage during the information mutual transmission between two authorized participants, i.e. Alice and Bob, a quantum dialogue protocol based on the entanglement swapping between any two Bell states and the ...

Delayed-Choice Experiments and the Metaphysics of Entanglement [PDF]
, 2012 Delayed-choice experiments in quantum mechanics are often taken to undermine a realistic interpretation of the quantum state. More specifically, Healey has recently argued that the phenomenon of delayed-choice entanglement swapping is incompatible with ...

Coherent Control of Entanglement with Atomic Ensembles [PDF]
, 2011 Quantum networks are composed of quantum nodes which coherently interact by way of quantum channels. They offer powerful capabilities for quantum computation, communication, and metrology. A generic requirement for these realizations is the capability to

Optimal entanglement distribution policies in homogeneous repeater chains with cutoffs
npj Quantum Information, 2023 We study the limits of bipartite entanglement distribution using a chain of quantum repeaters that have quantum memories. To generate end-to-end entanglement, each node can attempt the generation of an entangled link with a neighbor, or perform an ...
