提出一种新型的基于三粒子3×2×2维非对称纠缠量子信道可控密集编码方案.控制者(Charlie)对其手中2维粒子进行局域测量控制信息发送者(Alice)和接收者(Bob)量子态塌缩,调控Alice和Bob量子态纠缠,实现Alice和Bob3×2维非对称量子信道纠缠调控.计算了Alice和Bob非对称密集编码平均信息传送量.分析表明,Charlie通过调节测量角θ的大小可以控制Alice和Bob平均信息传送量.利用三粒子最大纠缠程度的3×2×2维非对称纠缠量子信道,Charlie可以控制Alice和Bob密集编码传送信息量高于2比特,方案是高效的;对于非最大纠缠程度的量子信道,传送信息量受到Charlie测量角θ和三粒子量子态纠缠系数β共同调控.
