Photon Efficiency of High-Dimensional Quantum Key Distribution
Vera Uzunova, Marcin Jarzyna
We investigate entanglement-based quantum key distribution protocols, with particular emphasis on their efficiency under realistic conditions of satellite quantum communications, w…
Nontrivial Aharonov-Bohm effect and alternating dispersion of magnons in cone-state ferromagnetic rings
Vera Uzunova, Lukas Körber, Agapi Kavvadia +4
Soft magnetic dots in the form of thin rings have unique topological properties. They can be in a vortex state with no vortex core. Here, we study the magnon modes of such systems…
Analytic density of states of two-dimensional Chern insulator
Vera Uzunova, Krzysztof Byczuk
We present analytic expressions for the density of states and its consistent derivation for the two-dimensional Qi-Wu-Zhang (QWZ) Hamiltonian, a generic model for the Chern topolog…
Nonlinear spin dynamics of ferromagnetic ring in the vortex state and its application for spin-transfer nano-oscillator
Vera Uzunova, Boris A. Ivanov
We study a nonlinear spin dynamics of a ferromagnetic ring in a vortex state induced by the spin-polarized current. We also suggest to use the ferromagnetic ring as a free layer of…
Realistic photon-number resolution in generalized Hong-Ou-Mandel experiment
V. Ye. Len, M. M. Byelova, V. A. Uzunova +1
We consider realistic photodetection in a generalization of the Hong-Ou-Mandel experiment to the multimode case. The basic layout of this experiment underlies boson sampling -- a p…
