量子计数器擦除

Quantum counter erasure

Fedor Herbut

摘要:

干涉来自相干混频。它可以被纠缠抑制,后者可以被擦除,以恢复干扰。如果纠缠是一个最小项(最小项混合),就像大多数思想和真实实验报道的情况一样,出现了反擦除和反干涉的可能性。详细研究了最小项混合和最小项纠缠这一奇特现象。特别是,一个(任意)给定的最小项混合态的所有两项混合明确展出。在遥远系综分解方面,它们可能的实验室实现也是如此。

英文摘要:

Interference comes from coherent mixing. It can be suppressed by entanglement, and the latter can be erased so as to revive interference. If the entanglement is a mimal-term one (with minimal-term mixing), as is the case in most thought and real experiments reported, there appears the possibility of counter erasure and counter interference. This peculiar phenomenon of minimal-term mixing and minimal-term entanglement is investigated in detail. In particular, all two-term mixings of an (arbitrary) given minimal-term mixed state are explicitly exhibited. And so are their possible laboratory realizations in terms of distant ensemble decomposition.
