本文找到了一种研究优质差错基和量子纠错码的新方法,即群代数方法,它为差错基和量子码提供了一种代数表示.利用这种代数表示,建立了一系列关于最一般量子纠错码的线性规划限.
We find a new approach to study nice error bases and quantum error-correcting codes, namely the group algebra which gives us an algebraic notation for nice error bases and quantum codes. From this algebraic notation we establish a series of linear programming bounds on the most general quantum error-correcting codes.
