We propose various new techniques in quantum information theory, including a de Finetti style representation theorem for finite symmetric quantum states. As an application, we give a proof for the security of quantum key distribution which applies to arbitrary protocols.

  1. Finite-size quantum key distribution rates from R\'enyi entropies using conic optimization

    quant-ph 2025-11 unverdicted novelty 7.0

    A general conic optimization solver computes finite-size QKD rates from Rényi entropies more reliably than prior Frank-Wolfe methods.
