Our approach takes advantage of the state of PT -symmetric quantum theory to enhance eavesdropping success5 p.application/pdfengcc-by-nc-nd (c) Werner, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Intervenció de les comunicacionsDistribució de claus quànticaTreballs de fi de grauEavesdroppingQuantum key distributionBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
