Teleportation via spin-1/2 chain in solid-state quantum architecture
E. B. Fel'dman, S. I. Doronin, E. I. Kuznetsova +1
We propose the protocol for preparing the maximally entangled Bell state between remote qubits at the ends of the spin-1/2 chain governed by the specially engineered nearest-neighb…

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…

One-excitation spin dynamics in homogeneous closed chain governed by XX-Hamiltonian
E. B. Fel'dman, E. I. Kuznetsova, A. I. Zenchuk
We analytically investigate the one-excitation spin dynamics in a homogeneous closed spin-1/2 chain via diagonalization of the one-excitation block of the XX-Hamiltonian, which all…
