Quantum information and precision measurement [PDF]
, 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 ...

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

IET 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
Advanced 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.

Multi-step quantum secure direct communication using multi-particle Green-Horne-Zeilinger state
, 2006 A multi-step quantum secure direct communication protocol using blocks of multi-particle maximally entangled state is proposed. In this protocol, the particles in a Green-Horne-Zeilinger state are sent from Alice to Bob in batches in several steps.

Experimental implementation of a NMR entanglement witness
, 2012 Entanglement witnesses (EW) allow the detection of entanglement in a quantum system, from the measurement of some few observables. They do not require the complete determination of the quantum state, which is regarded as a main advantage.
