6 resultsVisualization of correlations in hybrid quantum systems
R. P. Rundle, B. I. Davies, V. M. Dwyer +2
The paper develops Wigner function representations for hybrid continuous‑ and discrete‑variable quantum systems, enabling clear visual distinction of quantum versus classical corre…
An elementary introduction to the geometry of quantum states with pictures
Joseph Avron, Oded Kenneth
The paper reviews how quantum states can be understood as high‑dimensional convex bodies and visualized through simple cross‑sections such as simplexes, balls, and hyper‑octahedra,…
Coherence of Purification
Arun Kumar Pati, Long-Mei Yang, Chiranjib Mukhopadhyay +2
The paper defines a new quantity called the coherence of purification as a measure of total quantumness of a single system, relates it to existing coherence and entanglement measur…
Non-Locality and Zero-Knowledge MIPs
Claude Crépeau, Nan Yang
The paper introduces a framework to measure the non‑local resources needed by simulators in zero‑knowledge multi‑prover interactive proofs, showing that some protocols are secure a…
Quantum correlations in two-level atomic system over Herring-Flicker coupling
Prasanta K. Panigrahi
The paper investigates how thermal quantum correlations such as entanglement and discord behave in three coupled two‑level atoms interacting via Herring‑Flicker coupling, comparing…
Realist Analysis of Six Controversial Quantum Issues
Art Hobson
The paper offers a realist philosophical analysis that resolves six controversial issues in quantum mechanics—quantization, field‑particle duality, superposition, entanglement, non…
