Testing Information Causality for General Quantum Communication Protocols
I-Ching Yu, Feng-Li Lin
Information causality was proposed as a physical principle to put upper bound on the accessible information gain in a physical bi-partite communication scheme. Intuitively, the inf…
Information Causality and Noisy Computations
Li-Yi Hsu, I-Ching Yu, Feng-Li Lin
We reformulate the information causality in a more general framework by adopting the results of signal propagation and computation in a noisy circuit. In our framework, the informa…
Deterministic Dense Coding and Faithful Teleportation with Multipartite Graph States
Ching-Yu Huang, I-Ching Yu, Feng-Li Lin +1
We proposed novel schemes to perform the deterministic dense coding and faithful teleportation with multipartite graph states. We also find the sufficient and necessary condition o…
Quantum Secret Sharing with Multi-level Mutually (Un-)Biased Bases
I-Ching Yu, Feng-Li Lin, Ching-Yu Huang
We construct general schemes for multi-partite quantum secret sharing using multi-level systems, and find that the consistent conditions for valid measurements can be summarized in…
