Some Aspects of Remote State Restoring in State Transfer Governed by XXZ-Hamiltonian
Georgii A. Bochkin, Sergei I. Doronin, Edward B. Fel'dman +4
We consider the remote state restoring and perfect transfer of the zero-order coherence matrix (PTZ) in a spin system governed by the XXZ-Hamiltonian conserving the excitation numb…
Multiple quantum NMR in solids as a method of determination of Wigner-Yanase skew information
S. I. Doronin, E. B. Fel'dman, I. D. Lazarev
A connection of the Wigner-Yanase skew information and multiple quantum (MQ) NMR coherences is considered at different temperatures and evolution times of nuclear spins with dipole…
Simulation of multiple-quantum NMR dynamics of spin dimer on quantum computer
S. I. Doronin, E. B. Fel'dman, E. I. Kuznetsova +1
Dymanics of spin dimers in multiple quantum NMR experiment is studied on the 5-qubit superconducting quantum processor of IBM {Quantum Experience} for the both {pure} ground and th…
Many-particle Entanglement in Multiple Quantum NMR Spectroscopy
S. I. Doronin, E. B Fel'dman, I. D. Lazarev
We use multiple quantum (MQ) NMR dynamics of a gas of spin-carrying molecules in nanocavities at high and low temperatures for an investigation of many-particle entanglement. A dis…
Experimental and theoretical investigations of quantum state transfer and decoherence processes in quasi-one-dimensional systems in multiple-quantum NMR experiments
G. A. Bochkin, S. I. Doronin, S. G. Vasil'ev +2
Multiple quantum (MQ) NMR methods \cite{Baum} are applied to the analysis of various problems of quantum information processing. It is shown that the two-spin/two-quantum Hamiltoni…
Calculation of the quantum discord in many-qubit systems
A. Y. Chernyavskiy, S. I. Doronin, E. B. Fel'dman
For the first time, we compute the quantum discord in bipartite systems containing up to nine qubits. An analytical expression is obtained for the discord in a bipartite system wit…
