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…
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…
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…
Simulation of three-spin evolution under XX Hamiltonian on quantum processor of IBM-Quantum Experience
S. I. Doronin, E. B. Fel'dman, A. I. Zenchuk
We simulate the evolution of three-node spin chain on the quantum processor of IBM Quantum Experience using the diagonalization of -Hamiltonian and representing the evolution o…
Complete structural restoring of transferred multi-qubit quantum state
E. B. Fel'dman, A. N. Pechen, A. I. Zenchuk
We develop the protocol for structural restoring of multi-quantum coherence matrices of the multi-qubit quantum state transferred from the sender to the receiver along a spin-1/2 c…
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…
