Quantum estimation of states and operations from incomplete data / S. Olivares, M. G. A. Paris. - In: THE EUROPEAN PHYSICAL JOURNAL. SPECIAL TOPICS. - ISSN 1951-6355. - 203:1(2012), pp. 185-192. [10.1140/epjst/e2012-01542-2]
Abstract:
We review minimum Kullback entropy principle for estima- tion of quantum states and operations and discuss its application to qubit and harmonic oscillator systems. In particular, we address the estimation of displacement and squeezing operations from incomplete data and show how to estimate the displacement or squeezing ampli- tude starting from photon-number resolving or on/off photodetection.
