Башкиров Е.К., Ступацкая М.П.
Аннотация:
Исследовано перепутывание состояний двух идентичных дипольно-связанных атомов, резонансно взаимодействующих с одномодовым тепловым полем в идеальном резонаторе. Найдена зависимость степени перепутывания от константы прямого дипольного взаимодействия для различных чистых и смешанного состояний атомов.
Abstract:
The entanglement between two dipole-coupled identical two-level atoms resonantly interacting with one-mode thermal field in lossless cavity has been investigated. The dependence of dipole strength on the degree of entanglement has been carried out for different pure and mixed atomic states.
