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

Advances 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.

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.

Particle-wave duality: a dichotomy between symmetry and asymmetry [PDF]

, 2012
Symmetry plays a central role in many areas of modern physics. Here we show that it also underpins the dual particle and wave nature of quantum systems. We begin by noting that a classical point particle breaks translational symmetry whereas a wave with ...

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.

Tubular Initial Conditions and Ridge Formation

Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
The 2D azimuth and rapidity structure of the two‐particle correlations in relativistic A+A collisions is altered significantly by the presence of sharp inhomogeneities in superdense matter formed in such processes. The causality constraints enforce one to associate the long‐range longitudinal correlations observed in a narrow angular interval, the so ...

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

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.

Dynamical Properties of Scaled Atomic Wehrl Entropy of Multiphoton JCM in the Presence of Atomic Damping

Advances in Condensed Matter Physics, Volume 2013, Issue 1, 2013., 2013
We study the dynamics of the atomic inversion, scaled atomic Wehrl entropy, and marginal atomic Q‐function for a single two‐level atom interacting with a one‐mode cavity field taking in the presence of atomic damping. We obtain the exact solution of the master equation in the interaction picture using specific initial conditions. We examine the effects

Negative entropy and information in quantum mechanics [PDF]

, 1997
A framework for a quantum mechanical information theory is introduced that is based entirely on density operators, and gives rise to a unified description of classical correlation and quantum entanglement. Unlike in classical (Shannon) information theory,

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.

Quantum Private Comparison: A Review

, 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 ...
