量子信道中的等距部分纠缠字母态
Equally-distant partially-entangled alphabet states for quantum channels
摘要：
每个贝尔态都具有这样的性质，即只对一个量子比特执行局部操作，就可以生成完整的贝尔基。也就是说，由局部操作生成的状态是完全可区分的。这种显著的性质是由于两个粒子之间的最大量子纠缠。我们提出了一组局域幺正变换，它从部分纠缠的两量子比特态中产生一组四个相互距离相等的最大可区分态。我们讨论了基于这些字母表态的量子密集编码。
英文摘要：
Each Bell state has the property that by performing just local operations on one qubit, the complete Bell basis can be generated. That is, states generated by local operations are totally distinguishable. This remarkable property is due to maximal quantum entanglement between the two particles. We present a set of local unitary transformations that generate out of partially entangled two-qubit state a set of four maximally distinguishable states that are mutually equally distant. We discuss quantum dense coding based on these alphabet states.
