W-Class States—Identification and Quantification of Bell-CHSH Inequalities’ Violation [PDF]
EntropyWe discuss a family of W-class states describing three-qubit systems. For such systems, we analyze the relations between the entanglement measures and the nonlocality parameter for a two-mode mixed state related to the two-qubit subsystem.

Dephasing Process of a Single Atom Interacting with a Two-Mode Field [PDF]
Entropy, 2021 We consider the interaction of a qubit system with a two-mode field in the presence of multi-photon transition and phase damping effect. We use the master equation to obtain the density operator when the qubit is initially prepared in its excited state ...

Classical Data in Quantum Machine Learning Algorithms: Amplitude Encoding and the Relation Between Entropy and Linguistic Ambiguity [PDF]
EntropyThe Categorical Compositional Distributional (DisCoCat) model has been proven to be very successful in modelling sentence meaning as the interaction of word meanings. Words are modelled as quantum states, interacting guided by grammar.

Photon losses depending on polarization mixedness [PDF]
European Physical Journal D, 2009 We introduce a quantum channel describing photon losses depending on the degree of polarization mixedness. This can be regarded as a model of quantum channel with correlated errors between discrete and continuous degrees of freedom. We consider classical information over a continuous alphabet encoded on weak coherent states as well as classical ...

Bounds on Mixed State Entanglement [PDF]
Entropy, 2020 In the general framework of d 1 × d 2 mixed states, we derive an explicit bound for bipartite negative partial transpose (NPT) entanglement based on the mixedness characterization of the physical system.

Research Paper: Investigation of the Relationship of the Degree of Mixedness and Entanglement of the Bipartite Spin Coherent States [PDF]
فیزیک کاربردی ایران, 2021 In this work, superposition of spin coherent states composed of two qubits is formed and by calculating the geometric measure of mixing of the system introduced in this work, the degree of mixedness of the studied state is investigated. In the following,

Genealogy, 2022 Developments in reproductive (e.g., assisted reproduction, surrogacy) and genetic technologies (commercial DNA ancestry testing) have opened new routes to mixedness that disrupt the relationship between multiracialism and family.
