M-neighbor approximation in one-qubit state transfer along zigzag and alternating spin-1/2 chains
E. B. Fel'dman, A. I. Zenchuk
We consider the -neighbor approximation in the problem of one-qubit pure state transfer along the -node zigzag and alternating spin chains governed by the -Hamiltonian w…
Two-channel spin-chain communication line and simple quantum gates
J. Stolze, A. I. Zenchuk
We consider the remote creation of a mixed state in a one-qubit receiver connected to two two-qubit senders via different channels. {Channels are assumed to be chains of spins (qub…
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…
Multidimensional linearizable system of -wave type equations
A. I. Zenchuk
A linearizable version of multidimensional system of -wave type nonlinear PDEs is proposed. This system is derived using the spectral representation of its solution via the proc…
A five-dimensional solitary-wave first order nonlinear PDE integrable by dressing method
A. I. Zenchuk
We derive a five-dimensional nonlinear first order matrix PDE which is a generalization of the completely integrable (2+1)-dimensional -wave equation. Similar to the $\bar\parti…
Remote control of quantum correlations in two-qubit receiver via three-qubit sender
S. I. Doronin, A. I. Zenchuk
We study the problem of remote control of quantum correlations (discord) in a sub-system of two qubits (receiver) via the parameters of the initial state of another sub-system of t…
