Generating quantum discord between two distant Bose–Einstein condensates with Bell-like detection
Generating quantum discord between two distant Bose–Einstein condensates with Bell-like detection
We propose a technique that enables the creation of quantum discord between two distant nodes, each containing a cavity consist of the Bose-Einstein condensate, by applying a non-ideal Bell-like detection on the output modes of optical cavities. We find the covariance matrix of the system after the non-ideal Bell-like detection, …
