摘要
I construct a quantum error correction code (QECC) in higher spin systems using the idea of multiplicative group character. Each state quantum particle is encoded as five state quantum registers. By doing so, this code can correct any quantum error arising from any one of the five quantum registers. This code generalizes the well-known five qubit perfect code in spin-1/2 systems and is shown to be optimal for higher spin systems. I also report a simple algorithm for encoding. The importance of multiplicative group character in constructing QECCs will be addressed.
