Quantum speedup and non-Markovianity of an atom in structured reservoirs:pseudomodes as a good description of environmental memory
《Communications in Theoretical Physics》2024年第8期60-66,共7页Maryam Hadipour Soroush Haseli Saeed Haddadi 
supported by Semnan University under Contract No. 21270。
Following the recent paper(Teittinen et al 2019 New J. Phys. 21 123041), one can see that in general there is no simple relation between non-Markovianity and quantum speed limit. Here, we investigate the connection be...
