Abstract

Vazgeçilmez avantajlarıyla
birlikte, kuantum Fisher bilişimi (QFI), bilinmeyen bir parametrenin değerini
belirlemek ve çözünürlük hassasiyetini geliştirmek için anahtar özkaynaklardır.
Bu çalışmada, biri Jaynes-Cummings kovuğunda diğeri ise
tamamen izole edilmiş, uzaysal olarak ayrılmış iki atomun çiftlenim sabitine
ilişkin olarak QFI dinamikleri incelenecek ve QFI’nın, en uygun tahmin için kuantum Cramér-Rao sınırı doyurulacak şekilde
parametreler ayarlanarak maksimize edilebileceği gösterilecektir. 

Keywords

kuantum parametre tahmini, kuantum Fisher bilişimi, Jaynes-Cummings modeli
