Computing quantum discord is NP-complete
New Journal of Physics, 2014 We study the computational complexity of quantum discord (a measure of quantum correlation beyond entanglement), and prove that computing quantum discord is NP-complete.

Enhance Capacity Region of Multi‐Class IIoT Network by Applying Entanglement Assistance Protocol
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.ABSTRACT In the Industrial Internet of Things (IIoT) context, heterogeneous IIoT nodes need diverse performance requirements, including throughput and quality of service (QoS). These IIoT nodes transmit data over a common shared communication medium. The existing critical challenge arises in efficiently scheduling access to this shared medium among a ...

High‐Dimensional Quantum Communication: Benefits, Progress, and Future Challenges
Advanced Quantum Technologies, Volume 2, Issue 12, December 2019., 2019 Quantum communication with states living in d‐dimensional Hilbert spaces, qudits, yields great benefits. However, qudits generation, transmission, and detection is not a simple task to accomplish. This review presents the state‐of‐the‐art on the generation, propagation, and measurement of high‐dimensional quantum states, highlighting their advantages ...

Optimal distillation of three-qubit W states
, 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 ...

The apex of the family tree of protocols: Optimal rates and resource inequalities [PDF]
, 2011 We establish bounds on the maximum entanglement gain and minimum quantum communication cost of the Fully Quantum Slepian-Wolf protocol in the one-shot regime, which is considered to be at the apex of the existing family tree in Quantum Information Theory.

Approaches to Quantum Remote Memory Attestation
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.We provide a comprehensive analysis of methods for preforming remote memory attestation using quantum communication, and use this to create an improved method. ABSTRACT In this article, we uncover flaws and pitfalls of a quantum‐based remote memory attestation procedure for Internet of things devices.

Virtual Correlations in Single Qutrit
Advances in Mathematical Physics, Volume 2016, Issue 1, 2016., 2016 We construct the positive invertible map of the mixed states of a single qutrit onto the antisymmetrized bipartite qutrit states (quasifermions). It is shown that using this one‐to‐one correspondence between qutrit states and states of two three‐dimensional quasifermions one may attribute hidden entanglement to a single mixed state of qutrit.

Advanced 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
