Long distance entanglement and high-dimensional quantum teleportation in the Fermi–Hubbard model

S Abaach, Z Mzaouali, M El Baz - Scientific Reports, 2023 - nature.com
The long distance entanglement in finite size open Fermi–Hubbard chains, together with the
end-to-end quantum teleportation are investigated. We show the peculiarity of the ground …

[HTML][HTML] Almost perfect transmission of multipartite entanglement through disordered and noisy spin chains

R Vieira, G Rigolin - Physics Letters A, 2020 - Elsevier
We show how to efficiently send an M-partite entangled state along a spin chain of arbitrary
size. Specifically, we show how an entangled M-partite W sate can be almost flawlessly …

We investigate how robust is the modified XX spin-1/2 chain of Vieira and Rigolin (Phys Lett
A 382: 2586, 2018) in transmitting entanglement when several types of disorder and noise …

Extension of the remotely creatable region via the local unitary transformation on the receiver side

GA Bochkin, AI Zenchuk - arXiv preprint arXiv:1511.03507, 2015 - arxiv.org
We consider the remote state creation via the homogeneous spin-1/2 chain and show that
the significant extension of the creatable region can be achieved using the local unitary …

Quantum state transfer using 1D Heisenberg Hamiltonian on quasi-1D lattices

CB Pushpan, AK Pal - arXiv preprint arXiv:2306.08440, 2023 - arxiv.org
We consider transfer of single and multi-qubit states on a quasi-1D lattice, where the time
evolutions involved in the state transfer protocol are generated by only 1D Hamiltonians. We …

Temperature-dependent remote control of polarization and coherence intensity with sender's pure initial state

EB Fel'dman, EI Kuznetsova, AI Zenchuk - Quantum Information …, 2016 - Springer
We study the remote creation of the polarization and intensity of the first-order coherence (or
coherence intensity) in long spin-1/2 chains with one-qubit sender and receiver. Therewith …

Remote control of quantum correlations in a two-qubit receiver by a three-qubit sender

SI Doronin, AI Zenchuk - Theoretical and Mathematical Physics, 2016 - Springer
We study remote control of quantum correlations (discord) in a subsystem of two qubits
(receiver) via parameters of the initial state of another three-qubit subsystem (sender) …
