Optimal distillation of three-qubit W states

open access: yes, 2010
Some of the asymmetric three qubit $W$ states are used for perfect teleportation, superdense coding and quantum information splitting. We present the protocols for the optimal distillation of the asymmetric as well as the symmetric $W$ states from a ...

In Situ TEM Investigation of the Lithiation and Delithiation Process Between Graphene Sheets in the Presence of Atomic Defects

open access: yesAdvanced Functional Materials, Volume 34, Issue 41, October 8, 2024.
The lithiation and delithiation processes within graphene sheets is studied in‐situ by spherical and chromatic aberration‐corrected transmission electron microscopy. Ultrathin fcc lithium crystals are found to nucleate at single carbon vacancies during lithiation. However, during delithiation, oxygen atoms initially embedded inside the lithium crystals

Femtoscopic and Nonfemtoscopic Two‐Particle Correlations in A + A and p + p Collisions at RHIC and LHC Energies

open access: yesAdvances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
The theoretical review of the last femtoscopy results for the systems created in ultrarelativistic A + A, p + p, and p + Pb collisions is presented. The basic model, allowing to describe the interferometry data at SPS, RHIC, and LHC, is the hydrokinetic model.

Quantum Private Comparison: A Review

open access: yes, 2013
As an important branch of quantum secure multiparty computation, quantum private comparison (QPC) has attracted more and more attention recently. In this paper, according to the quantum implementation mechanism that these protocols used, we divide these ...

Investigating delay of the media access control protocols for IoT‐RoF using quantum entanglement

open access: yesIET Networks, Volume 13, Issue 4, Page 324-337, July 2024.
IoT‐RoF QE‐based: MAC Protocol Delay Study. Abstract One of the significant challenges of the Radio over fibre (RoF) Medium Access Control (MAC) protocol is the propagation delay. This delay can lead to serious issues, such as higher propagation delay resulting in collisions and unnecessary retransmissions.

N-qubit Quantum Teleportation, Information Splitting and Superdense Coding through the composite GHZ-Bell Channel

open access: yes, 2011
We introduce a general odd qubit entangled system composed of GHZ and Bell pairs and explicate its usefulness for quantum teleportation, information splitting and superdense coding.

Quantum information and precision measurement [PDF]

open access: yes, 1999
We describe some applications of quantum information theory to the analysis of quantum limits on measurement sensitivity. A measurement of a weak force acting on a quantum system is a determination of a classical parameter appearing in the master ...

Multi‐hop joint remote state preparation of general hybrid entangled multi‐qudit states via distinct Einstein‐Podolsky‐Rosen channels

open access: yesIET Quantum Communication, Volume 5, Issue 2, Page 173-184, June 2024.
We propose a novel JRSP protocol for transmitting general multi‐qudit states over quantum networks, providing a promising pathway to utilize the available Einstein‐Podolsky‐Rosen (EPR) channels with different levels. Firstly, we investigate the joint remote state preparation scheme with the same‐level EPR pairs.

Scalable Quantum Spin Networks from Unitary Construction

open access: yesAdvanced Quantum Technologies, Volume 7, Issue 2, February 2024.
A unitary‐based design of quantum spin networks (SNs) allows the generation of various quantum information processing. Such SNs are scalable and have applications for routing quantum information, for generation of bipartite and multipartite entangled states, and for quantum sensing.
