Abstract

En 中文
We present a systematic way to construct p-ary quantum error correcting codes using logic functions. As a consequence, for a given function with APC distance d' >= 2, we can construct quantum codes with parameters ((n, K, d))(p) and gain a lower bound of K for all 2 <= d <= d'. The basic states of the constructed quantum codes can be stated and the sufficient conditions for saturating quantum Singleton bound are also discussed. We give quantum codes [[5, 1, 3]](p) with p prime, [[6, 0, 4]], [[ 6, 2, 3]](p) with p > 2 prime and [[2n, 2n 2, 2]] as examples constructed in this way.
