1. Arxiv - Direct Observation of Coherent Population Trapping in a Superconducting Artificial Atom (5 pages)

Normally, superconducting artificial atoms absorb photons at a particular frequency. However applying a second field at a different frequency can be used to prevent this absorption, making the artificial atom effectively transparent. Superconducting artificial atoms offer fast and reliable processing, and light offers fast and reliable transmission over long distances.

2. A new study has compared the strength of classical and quantum correlations in a simple number guessing game and found no difference in performance. Further, the physicists found that a third form of correlations - post-quantum correlations - could outperform both quantum and classical forms
