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…
Optimal remote restoring of quantum states in communication lines via local magnetic field
E. B. Fel'dman, A. N. Pechen, A. I. Zenchuk
Optimal state transport across spin chains, which are proposed as quantum wires for information transfer in solid state quantum architectures, is an important topic for quantum tec…
Quantum algorithms for calculating determinant and inverse of matrix and solving linear algebraic systems
Alexander I. Zenchuk, Georgii A. Bochkin, Wentao Qi +2
We propose quantum algorithms, purely quantum in nature, for calculating the determinant and inverse of an matrix (depth is ) which is a simple mo…
