Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

Global Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Quantum computing: The power of discord [PDF]

Nature, 2011
Physicists have always thought quantum computing is hard because quantum states are incredibly fragile. But could noise and messiness actually help things along?

Tales of Cyberspace and Artificial Intelligence: Diverging Stakeholderships?

Global Policy, EarlyView.
ABSTRACT This article traces the evolution of the Internet from the 1990s to the 2020s and compares it with the development of Artificial Intelligence (AI), particularly following the public launch of ChatGPT in late 2022. It identifies both parallels and divergencies between these two overlapping technological domains, focusing on the growing ...

Bipartite mechanical systems of a laser-driven optomechanical cavity

Results in Optics
We investigate the correlation of mechanical systems of nondegenerate three-level laser with parametric oscillator in optomechanical cavity coupled to a two-mode squeezed vacuum reservoir.

Quantum correlations between each two-level system in a pair of atoms and general coherent fields

Results in Physics, 2016
The quantitative description of the quantum correlations between each two-level system in a two-atom system and the coherent fields initially defined in a coherent state in the framework of power-law potentials (PLPCSs) is considered.

Trading Zones Between Thick and Thin: Anthropological Description as Scaffold or Mosaic

American Anthropologist, EarlyView.
ABSTRACT Referring to the work of historian of science Peter Galison, I argue that anthropology requires thin description as an essential counterpart for thick description. Thin accounts provide the scaffolding within which thick descriptions sit. Galison uses the idea of a “trading zone” connecting different communities who, despite their differences (

Dynamics of quantum correlations in four-qubit XXZ Heisenberg model with external magnetic field

Results in Physics
In this paper we argue about the quantum correlation (quantum entanglement and geometric quantum discord) in four-qubit XXZ Heisenberg Model. Here, the influence of uniform magnetic field on the dynamics of quantum correlation in cases of the ...

Quantum Correlation Based on Uhlmann Fidelity for Gaussian States

Entropy, 2018
A quantum correlation N F G , A for ( n + m ) -mode continuous-variable systems is introduced in terms of local Gaussian unitary operations performed on Subsystem A based on Uhlmann fidelity F.
