Abstract
In quantum information, how to properly formulate the Knill-Laflamme (KL) conditions for infinite dimensional systems has long remained an open problem. In this talk, we use the subfactor theory and quantum Fourier analysis to give the renormalized Kraus decomposition and renormalized Knill-Laflamme (KL) conditions for bi-module quantum channel. Furthermore, we use these to
give an application about the near optimal fidelity.
