Cross Correlations

The authors investigate current noise cross correlations (CCs) through coupled double quantum dots under transport conditions. It is demonstrated that positive CCs relate to either thermal fluctuations at nonzero temperature or quantum tunneling processes at zero temperature. These measurable CCs could service as the sensitive indicators of entanglements between electronic spins in double dots coupled by exchange interactions.
