A simple test for hidden variables in spin-1 system
Alexander A. Klyachko, M. Ali Can, Sinem Binicioğlu +1
We resolve an old problem about the existence of hidden parameters in a three-dimensional quantum system by constructing an appropriate Bell's type inequality. This reveals a noncl…
Quantification of entanglement via uncertainties
Alexander A. Klyachko, Barış Öztop, Alexander S. Shumovsky
We show that entanglement of pure multi-party states can be quantified by means of quantum uncertainties of certain basic observables through the use of measure that has been initi…
Entanglement of a Single Spin-1 Object: An Example of Ubiquitous Entanglement
Sinem Binicioglu, M. Ali Can, Alexander A. Klyachko +1
Using a single spin-1 object as an example, we discuss a recent approach to quantum entanglement. The key idea of the approach consists in presetting of basic observables in the ve…
General entanglement
Alexander A. Klyachko, Alexander S Shumovsky
The paper contains a brief review of an approach to quantum entanglement based on analysis of dynamic symmetry of systems and quantum uncertainties, accompanying the measurement of…
Measurable entanglement
Alexander Klyachko, Barış Öztop, Alexander S. Shumovsky
Amount of entanglement carried by a quantum bipartite state is usually evaluated in terms of concurrence (see Ref. 1). We give a physical interpretation of concurrence that reveals…
Single-particle entanglement
M. Ali Can, Alexander Klyachko, Alexander Shumovsky
Using the approach to quantum entanglement based on the quantum fluctuations of observables, we show the existence of perfect entangled states of a single "spin-1" particle. We giv…
