Multiterminal source coding with complementary delivery
Akisato Kimura, Tomohiko Uyematsu
A coding problem for correlated information sources is investigated. Messages emitted from two correlated sources are jointly encoded, and delivered to two decoders. Each decoder h…
Near ML detection using Dijkstra's algorithm with bounded list size over MIMO channels
Atsushi Okawado, Ryutaroh Matsumoto, Tomohiko Uyematsu
We propose Dijkstra's algorithm with bounded list size after QR decomposition for decreasing the computational complexity of near maximum-likelihood (ML) detection of signals over…
Universal Coding for Lossless and Lossy Complementary Delivery Problems
Shigeaki Kuzuoka, Akisato Kimura, Tomohiko Uyematsu
This paper deals with a coding problem called complementary delivery, where messages from two correlated sources are jointly encoded and each decoder reproduces one of two messages…
Tomography increases key rates of quantum-key-distribution protocols
Shun Watanabe, Ryutaroh Matsumoto, Tomohiko Uyematsu
We construct a practically implementable classical processing for the BB84 protocol and the six-state protocol that fully utilizes the accurate channel estimation method, which is…
Universal coding for correlated sources with complementary delivery
Akisato Kimura, Tomohiko Uyematsu, Shigeaki Kuzuoka
This paper deals with a universal coding problem for a certain kind of multiterminal source coding system that we call the complementary delivery coding system. In this system, mes…
Constructing quantum error-correcting codes for p^m-state systems from classical error-correcting codes
Ryutaroh Matsumoto, Tomohiko Uyematsu
We generalize the construction of quantum error-correcting codes from GF(4)-linear codes by Calderbank et al. to p^m-state systems. Then we show how to determine the error from a s…
