    Construction method of optimal codebook based on Zadoff-Chu matrix by Yubo LI, Shengyi LIU, Jingjing ZHANG, Dongyan JIA

    Published 2020-03-01
    “…Codebooks with low-coherence have wide utilization in code division multiple access (CDMA) communications,quantum information theory,compressed sensing and so on.In order to expand the number of codebooks,the restrictions on the transformation matrix were relaxed.Based on the Zadoff-Chu matrix,new codebooks were constructed using the difference set,almost difference set,and finite field character sum.The proposed codebooks were optimal or near optimal according to the Welch bound or Levenstein bound.Through experimental simulation,it is found that the deterministic measurement matrices constructed using these codebooks also have good performance in the process of compressed sensing.…”

    Quantum Contextual Hypergraphs, Operators, Inequalities, and Applications in Higher Dimensions by Mladen Pavičić

    Published 2025-01-01
    “…Quantum contextuality plays a significant role in supporting quantum computation and quantum information theory. The key tools for this are the Kochen–Specker and non-Kochen–Specker contextual sets. …”

    Horizon causality from holographic scattering in asymptotically dS3 by Victor Franken, Takato Mori

    Published 2024-12-01
    “…This statement is formalized by the connected wedge theorem, which can be proven using general relativity within AdS3 but also argued for using quantum information theory on the boundary, suggesting that the theorem applies to any holographic duality. …”
