Quantifying Entanglement

  title={Quantifying Entanglement},
  author={Vlatko Vedral and Martin Bodo Plenio and Markus Rippin and P. L. Knight},
We have witnessed great advances in quantum information theory in recent years. There are two distinct directions in which progress is currently being made: quantum computation and error correction on the one hand (for a short survey see [1,2]) and non–locality, Bell’s inequalities and purification on the other hand [3,4]. There has also been a number of papers relating the two (e.g. [5,6]). Our present work belongs to this second group. Recently it was realised that the CHSH (Clauser…

Detecting Violation of Bell Inequalities using LOCC Maximized Quantum Fisher Information and Entanglement Measures

The violation of Bell's theorem is a very simple way to see that there is no underlying classical interpretation of quantum mechanics. The measurements made on the photons shows that light signal

Uncertainty, monogamy, and locking of quantum correlations

The results lead to the conclusion that both measures can drop by an arbitrary amount when only a single qubit of a local system is lost.

General Paradigm for Distilling Classical Key From Quantum States

It is demonstrated that all quantum cryptographic protocols can be recast in a way which looks like entanglement theory, with the only change being that instead of distilling Einstein-Podolsky-Rosen (EPR) pairs, the parties distill private states.

Multipartite Entanglement: Transformations, Quantum Secret Sharing, Quantum Error Correction

This thesis investigates transformations between multipartite entangled states that only use local operations and classical communication, and proves the existence of AME states for any number of parties, if the dimension of the involved quantum systems is chosen appropriately.

Entanglement - A Queer In The World Of Quantum: Some Perspectives

The work is intended to represent some interesting and apparently peculiar features of entangled system in both pure as well as mixed states level. In the pure state level, we are largely concerned

Private States, Quantum Data Hiding, and the Swapping of Perfect Secrecy.

It is shown that for protocols that first distill private states, it is essentially optimal to use the standard quantum repeater protocol based on entanglement distillation and entanglements swapping, a setting called the quantum key repeater.

Distribution of quantum entanglement : principles and applications

The main focus of this thesis is to study the distribution of quantum entanglement via continuous interactions with ancillary particles, which I will call mediators, which includes, among others, indirect probing of the quantum nature of optomechanical mirrors, photosynthetic organisms, and gravitational interactions.

Local approach to quantum entanglement

A new approach to the analysis of entanglement, especially in continuous-variable states, is introduced and it is shown that it leads to the first systematic quantification of the (local)Entanglement in arbitrary bipartite non-Gaussian states.

Quantifying Entanglement

Since the revolutionary EPR-Bohm thought experiment, researchers inspired by Bell’s theorem have been experimentally generating and employing nonclassical correlations in the laboratory. Recently, on

Quantifying quantum coherence with quantum Fisher information

It is verified that the well-known quantum Fisher information (QFI) can be utilized to quantify the quantum coherence, as it satisfies the monotonicity under the typical incoherent operations and the convexity under the mixing of the quantum states.



Quantum correlations, local interactions and error correction

We consider the effects of local interactions upon quantum mechanically entangled systems. In particular we demonstrate that non-local correlations cannot increase through local operations on any of

Elements of Information Theory

The author examines the role of entropy, inequality, and randomness in the design of codes and the construction of codes in the rapidly changing environment.
