Fast convergence of Dynamic Capacities of GNS-Symmetric Quantum Channels
Paper i proceeding, 2026
We consider a quantum system described by a quantum channel Φ that is applied at every time step and study the time evolution of its information capacities. When Φ is a GNS symmetric channel (this includes Pauli channels for example), we give explicit exponential convergence bounds for the classical and quantum capacities. These bounds are in terms entropic properties of Φ.
