Causation Counterfactuals Relativity Entanglement
2016/6/13
We investigate whether standard counterfactual analyses of causation (CACs) imply that the outcomes of space-like separated measurements on entangled particles are causally related. While it has somet...
Thinking Outside the Box: The Essence and Implications of Quantum Entanglement
spin mind pixel quantum entanglement interconnectedness inseparableness
2015/8/3
Many experiments have shown that quantum entanglement is physically real. In this paper, we will discuss its ontological origin, implications and applications by thinking outside the standard interpre...
The Existence of Quantum Entanglement Catalysts.
Entanglement catalysts entanglement states entanglement
2012/11/29
Without additional resources, it is often impossible to transform one entangled quantum state into another with local quantum operations and classical communication. Jonathan and Plenio (Phys. Rev. Le...

Multipartite Quantum Entanglement Evolution Photosynthetic Complexes
2012/2/28
We investigate the evolution of entanglement in the Fenna-Matthew-Olson (FMO) complex based on simulations using the scaled hierarchy equation of motion (HEOM) approach. We examine the role of multipa...
The Super Operator System Structures and their applications in Quantum Entanglement Theory

Abstract: An operator system $\cl S$ with unit $e$, can be viewed as an Archimedean order unit space $(\cl S,\cl S^+,e)$. Using this Archimedean order unit space, for a fixed $k\in \bb N$ we construct...

We present an information geometric analysis of quantum entanglement generated by an s-wave scattering event between two minimum uncertainty Gaussian wave packets.
Quantum entanglement between a nonlinear nanomechanical resonator and a microwave field
Quantum entanglement nonlinear nanomechanical resonator microwave field
2010/11/11
We consider a theoretical model for a nonlinear nanomechanical resonator coupled to a superconducting microwave resonator. The nanomechanical resonator is driven parametrically at twice its resonance ...
Measurement-induced quantum entanglement recovery
Measurement-induced quantum entanglement recovery
2010/11/4
By using photon pairs created in parametric down conversion, we report on an experiment, which demonstrates that measurement can recover the quantum entanglement of two qubit system in a pure dephasi...

Quantum Entanglement Initiated Super Raman Scattering
2010/10/21
It has now been possible to prepare chain of ions in an entangled state and thus question arises — how the optical properties of a chain of entangled ions differ from say a chain of independent partic...
Quantum entanglement and entropy in particle creation
Quantum entanglement particle creation entropy
2010/3/18
We investigate the basic theoretical issues in the quantum entanglement of particle pairs created from the vacuum in a time-dependent background field or spacetime. Similar to entropy generation from ...
Quantum entanglement in a many-body system exhibiting multiple quantum phase transitions
Quantum phase transitions Many body systems
2010/7/5
We investigate the quantum entanglement-related features of the many-body model of Plastino and Moszkowski [N. Cimento 47 (1978) 470]. This is an exactly solvable N-body, SU2 two-level model exhibitin...

Nonlinear Functions Quantum Entanglement Generation Silicon Photonic Wire Waveguides
2015/7/16
Nonlinear optical phenomena are remarkably enhanced in silicon photonic wire waveguides with ultra-small cores. Efficient nonlinear functions, such as a wavelength conversion and high-purity entangled...
Quantum entanglement and a metaphysics of relations

2008/4/22
This paper argues for a metaphysics of relations based on a characterization of quantum entanglement in terms of non-separability, thereby regarding entanglement as a sort of holism. By contrast to a ...
