Mixed-state entanglement and quantum error correction. [PDF]

Physical Review A. Atomic, Molecular, and Optical Physics, 1996
Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs) provide two ways of protecting quantum states from interaction with the environment. In an EPP, perfectly entangled pure states are extracted, with some yield D, from a

Quantum Entanglement and Its Application in Quantum Communication

Journal of Physics: Conference Series, 2021
Since the concept of quantum entanglement was proposed, quantum entanglement has been paid more and more attention. Especially in recent years, with the interdisciplinary and interdisciplinary development of quantum informatics, the general definition ...

Correcting Quantum Errors with Entanglement [PDF]

, 2006
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error ...

Multidimensional quantum entanglement with large-scale integrated optics [PDF]

Science, 2018
Large-scale integrated quantum optics The ability to pattern optical circuits on-chip, along with coupling in single and entangled photon sources, provides the basis for an integrated quantum optics platform. Wang et al.

The controlled SWAP test for determining quantum entanglement [PDF]

Quantum Science and Technology, 2020
Quantum entanglement is essential to the development of quantum computation, communications, and technology. The controlled SWAP test, widely used for state comparison, can be adapted to an efficient and useful test for entanglement of a pure state. Here

Quantum search without entanglement [PDF]

, 1999
Entanglement of quantum variables is usually thought to be a prerequisite for obtaining quantum speed-ups of information processing tasks such as searching databases.

Quantum entanglement recognition

Physical Review Research, 2021
Entanglement constitutes a key characteristic feature of quantum matter. Its detection, however, still faces major challenges. In this paper, we formulate a framework for probing entanglement based on machine learning techniques. The central element is a

Quantum entanglement in the triangle network [PDF]

Physical Review A, 2020
Beyond future applications, quantum networks open interesting fundamental perspectives, notably novel forms of quantum correlations. In this work we discuss quantum correlations in networks from the perspective of the underlying quantum states and their ...

Entanglement 25 Years after Quantum Teleportation: Testing Joint Measurements in Quantum Networks

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.
