Disordered entanglers suffer the effects of localization of the electron wave function and random fluctuations in entanglement production. This manifests in the statistics of the concurrence, a measure of the produced two-qubit entanglement. We calculate the concurrence distribution as a function of the disorder strength within a random-matrix approach. We also identify significant constraints on the entanglement production as a consequence of the breaking/preservation of time-reversal symmetry. Additionally, our theoretical results are independently supported by simulations of disordered quantum wires based on a tight-binding model. 000044956 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-29400$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2012-35719-C02 000044956 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000044956 590__ $$a3.736$$b2014 000044956 591__ $$aPHYSICS, CONDENSED MATTER$$b14 / 66 = 0.212$$c2014$$dQ1$$eT1 000044956 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000044956 700__ $$aVillarrubia-Rojo, H. 000044956 700__ $$aFrustaglia, D. 000044956 700__ $$0(orcid)0000-0002-8726-7212$$aGopar, V.A.$$uUniversidad de Zaragoza 000044956 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDepartamento de Física Teórica$$cFísica Teórica 000044956 773__ $$g89, 7 (2014), 075429 [5 pp]$$pPhys.
