Influence of environment on quantum correlations in two-spin systems with dipole-dipole interactions
G. A. Bochkin, E. B. Fel'dman, E. I. Kuznetsova +1
An influence of environment on quantum correlations (entanglement and quantum discord) is studied in a two-spin-1/2 system with dipole-dipole interactions on the basis of Lindblad…
Transfer of 0-order coherence matrix along spin-1/2 chain
G. A. Bochkin, E. B. Fel'dman, I. D. Lazarev +2
In this work, we study transfer of coherence matrices along spin-1/2 chains of various length. Unlike higher order coherence matrices, 0-order coherence matrix can be perfectly tra…
Calculation of on the IBM quantum computer and the accuracy of one-qubit operations
G. A. Bochkin, S. I. Doronin, E. B. Fel'dman +1
A quantum algorithm for the calculation of is proposed and implemented on the five-qubit IBM quantum computer with superconducting qubits. We find . The error…
The exact solution for the free induction decay in a quasi-one-dimensional system in a multi-pulse NMR experiment
G. A. Bochkin, E. B. Fel'dman, S. G. Vasil'ev
The exact solution for the free induction decay in a one-dimensional system in the multi-pulse experiment is obtained at both high and low temperatures in the approximation of near…
Entanglement in block-scalable and block-scaled states
G. A. Bochkin, S. I. Doronin, A. I. Zenchuk
There is a special class of so-called block-scalable initial states of the sender whose transfer to the receiver through the spin chain results in multiplying {their} MQ-coherence…
Transfer of scaled multiple quantum coherence matrices
G. A. Bochkin, E. B. Fel'dman, A. I. Zenchuk
Multiple quantum (MQ) NMR coherence spectra, which can be obtained experimentally in MQ NMR, can be transferred from the sender to the remote receiver without mixing the MQ-coheren…
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…
Optimization of remote one- and two-qubit state creation via multi-qubit unitary transformations at sender and receiver sides
G. A. Bochkin, A. I. Zenchuk
We study the optimization problem for remote one- and two-qubit state creation via a homogeneous spin-1/2 communication line using the local unitary transformations of the multi-qu…
Remote one-qubit state control by pure initial state of two-qubit sender. Selective-region- and eigenvalue-creation
G. A. Bochkin, A. I. Zenchuk
We study the problem of remote one-qubit mixed state creation using a pure initial state of two-qubit sender and spin-1/2 chain as a connecting line. We express the parameters of c…
