  1. Resolution of Infrared Entanglement Divergences via the Extended Uncertainty Principle

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Under the Extended Uncertainty Principle, position variance saturates, and the entanglement entropy of harmonic chains and massless scalar fields saturates to a finite value with a discrete, evenly gapped entanglement...

  2. Correlation and Entanglement partners in Gaussian systems

    quant-ph 2025-12 conditional novelty 5.0 of 10

    For Gaussian states, every correlated single mode has a unique partner (pure states) or separate correlation/entanglement partners (mixed states), constructed from the state's complex structure.

    quant-ph 2024-11 conditional novelty 2.0 of 10

    A didactic review of Cramér-Rao bounds and Fisher information in quantum metrology, ending with a restatement of the author's published Gaussian squeezing-estimation formulas.
