Completely Bounded Qusi-Norms, Their Mutiplicativity, and New Additivity Results of Quantum Channels
Ke Li, Quanhua Xu
We obtain two new additivity results of quantum channels. The first one is the additivity of the channel Rényi information associated with the sandwiched Rényi divergence of order…
Finite-Blocklength and Exponential Analyses for Universal Entanglement and Coherence Distillation under Various Free Operations
Zhiwen Lin, Ke Li, Kun Fang
Historically, entanglement and coherence distillation focused on the distillable rate under full knowledge of the initial state. In this paper, we develop a unified finite-blocklen…
Reliability Function of Classical-Quantum Channels
Ke Li, Dong Yang
We study the reliability function of general classical-quantum channels, which describes the optimal exponent of the decay of decoding error when the communication rate is below th…
Multi-Receiver Quantum Dense Coding with Non-Symmetric Quantum Channel
Chang-Bao Fu, Shou Zhang, Ke Li +2
A two-receiver quantum dense coding scheme and an -receiver quantum dense coding scheme, in the case of non-symmetric Hilbert spaces of the particles of the quantum channel, are…
