With entanglement-assisted (EA) formalism, arbitrary classical linear codes
are allowed to transform into EAQECCs by using pre-shared entanglement between
the sender and the receiver. In this paper, based on classical cyclic MDS codes
by exploiting pre-shared maximally entangled states, we construct two families
of $q$-ary entanglement-assisted quantum MDS codes
$[[\frac{q^{2}+1}{a},\frac{q^{2}+1}{a}-2(d-1)+c,d;c]]$, where q is a prime
power in the form of $am+l$, and $a=(l^2+1)$ or $a=\frac{(l^2+1)}{5}$. We show
that all of $q$-ary EAQMDS have minimum distance upper limit much larger than
the known quantum MDS (QMDS) codes of the same length. Most of these $q$-ary
EAQMDS codes are new in the sense that their parameters are not covered by the
codes available in the literature.

循环码中的两个纠缠辅助量子MDS码系列
使用纠缠辅助(EA)形式,通过使用发送者和接收者之间的预共享纠缠,可以将任意经典线性代码转换为EAQECC。在本文中,我们基于经典循环MDS代码,通过利用预共享的最大纠缠态,构造了两个$ q $元纠缠辅助量子MDS代码$ [[\ frac {q ^ {2} +1} { a},\ frac {q ^ {2} +1} {a} -2(d-1)+ c,d; c]] $,其中q是$ am + l $形式的素数,和$ a =(l ^ 2 + 1)$或$ a = \ frac {(l ^ 2 + 1)} {5} $。我们显示,所有$ q $ ary EAQMDS的最小距离上限远大于相同长度的已知量子MDS(QMDS)码。这些$ q $ ary EAQMDS代码中的大多数都是新的,因为它们的参数未包含在文献中的代码中。
