We thoroughly analyse the distance between quantum states that has been applied to state-dependent cloning and partly studied in the previous work of the author [Phys. Rev. A 66, 042304 (2002)]. Elementary proofs of its significant properties are given.

Discussion (0). Continue with ORCID to comment.

  1. Quantum Information Decoupling Beyond Finite Dimensions

    quant-ph 2026-07 accept novelty 7.0 of 10

    Under finite entropy of the manipulated system, infinite-dimensional IID decoupling and quantum state merging achieve the same optimal rates as in finite dimensions (H(A) and 1/2 I(A:R)).

  2. Maximum channel entropy principle and microcanonical channels

    quant-ph 2025-08 unverdicted novelty 7.0 of 10

    A maximum-entropy principle for quantum channels yields thermal channels with exponential form, analogous to thermal states.
