New bound on -setting Bell locality of a nonseparable Werner state
Elena R. Loubenets
In many quantum applications it is important to know whether or not a Bell nonlocal two-qudit state exhibits its nonlocality under correlation scenarios with some given numbers $S_…
Modelling optimal implementation of an arbitrary -qubit quantum gate within the generalized Bloch vectors formalism
Elena R. Loubenets, Sergey Kuznetsov
The optimal implementation of quantum gates for closed -qubit systems is one of the key challenges for practical realization of many quantum information processing tasks. In the…
High-spin measurements in an arbitrary two-qudit state
Elena R. Loubenets, Louis Hanotel
Violation of the CHSH inequality by a bipartite quantum state is now used in many quantum applications. However, the explicit analytical expression for the maximal value of the CHS…
Nonviolation of the CHSH inequality under local spin-1 measurements on two spin qutrits
Louis Hanotel, Elena R. Loubenets
In the present paper, based on the general analytical expression [arXiv:2412.03470] for the maximum of the CHSH expectation under local Alice and Bob spin- measurements in a two…
Geometric quantum discord of an arbitrary two-qudit state: the exact value and general upper bounds
Elena R. Loubenets, Louis Hanotel
The geometric quantum discord of a two-qudit state has been studied in many papers, however, its exact analytical value in the explicit form is known only for a general two-qubit s…
