The interference is mediated by a strong classical field that couples a weak probe field to the atomic coherence through a resonant Raman transition. Interference can be observed between a prepared spin coherence and another propagating optical field, or between multiple {\\Lambda} transitions driving a single spin coherence. In principle, the interference in each scheme can yield a near unity visibility.","authors_text":"B. C. Buchler, B. M. Sparkes, G. T. Campbell, M. Hosseini, P. K.
