Activation of zero-error classical capacity in low-dimensional quantum systems
Jeonghoon Park, Jun Heo
Channel capacities of quantum channels can be nonadditive even if one of two quantum channels has no channel capacity. We call this phenomenon \emph{activation} of the channel capa…
Improved Reconciliation With Polar Codes In Quantum Key Distribution
Sunghoon Lee, Jooyoun Park, Jun Heo
Quantum key distribution (QKD) is a cryptographic system that generates an information-theoretically secure key shared by two legitimate parties. QKD consists of two parts: quantum…
On the relation between a graph code and a graph state
Yongsoo Hwang, Jun Heo
A graph state and a graph code respectively are defined based on a mathematical simple graph. In this work, we examine a relation between a graph state and a graph code both obtain…
Fault-tolerant conversion between stabilizer codes by Clifford operations
Yongsoo Hwang, Byung-Soo Choi, Young-chai Ko +1
We propose a scheme that converts a stabilizer code into another stabilizer code in a fault tolerant manner. The scheme first puts both codes in specific forms, and proceeds the co…
