In this sense, quantum information theory is underdeveloped similarly to how quantum physics was underdeveloped before Erwin Schrödinger introduced his famous equation for the evolution of a quantum wave function. In this review article, we cope with the problem of time for one of the central quantities in quantum information theory: entropy. Recently, a replica trick formalism, the so-called ‘multiple parallel world’ formalism, has been proposed that revolutionizes entropy evaluation for quantum systems. This formalism is one of the first attempts to introduce ‘time’ in quantum information theory. With the total entropy being conserved in a closed system, entropy can flow internally between subsystems; however, we show that this flow is not limited only to physical correlations as the literature suggest. The nonlinear dependence of entropy on the density matrix introduces new types of correlations with no analogue in physical quantities. Evolving a number of replicas simultaneously makes it possible for them to exchange particles between different replicas. We will summarize some of the recent news about entropy in some example quantum devices. Moreover, we take a quick look at a new correspondence that was recently proposed that provides an interesting link between quantum information theory and quantum physics. The mere existence of such a correspondence allows for exploring new physical phenomena as the result of controlling entanglement in a quantum device 000902778 536__ $$0G:(DE-HGF)POF4-5224$$a5224 - Quantum Networking (POF4-522)$$cPOF4-522$$fPOF IV$$x0 000902778 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000902778 7001_ $$0P:(DE-Juel1)174097$$avan Steensel, Alwin$$b1$$ufzj 000902778 7001_ $$0P:(DE-HGF)0$$aNazarov, Yuli V.$$b2 000902778 773__ $$0PERI:(DE-600)2014734-X$$a10.3390/e21090854$$gVol. 21, no. 9, p. 854 -$$n9$$p854 -$$tEntropy$$v21$$x1099-4300$$y2019 000902778 8564_ $$uhttps://juser.fz-juelich.de/record/902778/files/entropy-21-00854.pdf$$yOpenAccess 000902778 909CO $$ooai:juser.fz-juelich.de:902778$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000902778 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171686$$aForschungszentrum Jülich$$b0$$kFZJ 000902778 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)174097$$aForschungszentrum Jülich$$b1$$kFZJ 000902778 9131_ $$0G:(DE-HGF)POF4-522$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5224$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Computing$$x0 000902778 9141_ $$y2021 000902778 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-05-04 000902778 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000902778 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bENTROPY-SWITZ : 2019$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000902778 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-05-04 000902778 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-05-04 000902778 920__ $$lyes 000902778 9201_ $$0I:(DE-Juel1)PGI-2-20110106$$kPGI-2$$lTheoretische Nanoelektronik$$x0 000902778 980__ $$ajournal 000902778 980__ $$aVDB 000902778 980__ $$aUNRESTRICTED 000902778 980__ $$aI:(DE-Juel1)PGI-2-20110106 000902778 9801_ $$aFullTexts
