Dualistic operational characterization of device-dependent correlation sets via convex analysis in the Bell scenario
Ryosuke Nogami, Jaeha Lee
We analyze device-dependent correlation sets generated by fixed local dichotomic measurements for two-qubit systems in the Bell scenario. We consider three fundamental st…

On the operational and algebraic quantum correlations
Shun Umekawa, Jaeha Lee
We investigate the intrinsic ambiguity in the definition of correlation functions arising from the inevitable invasiveness of quantum measurements. While algebraic correlations def…
