quantum information theory

The researchers explored the practicality of dense coding by elaborating 21 classes of dense coding capacities with different encoder-decoder pairs, where the encoders are constrained by the resource theory of asymmetry and the decoders are constrained by various locality conditions.

We investigate practical dense coding by imposing locality restrictions on decoders and symmetry restrictions on encoders within the …

We give the first systematic study on the second order asymptotics of the operational task of coherence distillation with and without …

We study classical communication over a noisy quantum channel when bipartite states are preshared between the sender and the receiver, …

The unextendibility or monogamy of entangled states is a key property of quantum entanglement. Unlike conventional ways of expressing …

Recent research by a team at Southern University of Science and Technology (SUSTech) introduced a new resource theory of quantum channels and applied it to study communication over quantum channels.

In this paper we investigate the relationship between direct-sum majorization formulation of uncertainty relations and entanglement, …
