Rev. Lett. 110 230601, Mazzola et al 2013 Phys. Rev. Lett. 110 230602). This method allows the replacement of two projective measurements of the energy of the driven system with qubit tomography of an ancilla that is appropriately coupled to it. We highlight that this method could be employed to obtain the work statistics of closed as well as open driven system, even in the strongly dissipative regime. We then illustrate an implementation of the method in a circuit QED setup, which allows one to experimentally obtain the work statistics of a parametrically driven harmonic oscillator. Our implementation is an extension of the original method, in which two ancilla-qubits are employed and the work statistics are retrieved through two-qubit state tomography. Our simulations demonstrate the experimental feasibility. 000063124 536__ $$9info:eu-repo/grantAgreement/EUR/COST/MP1209$$9info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUP$$9info:eu-repo/grantAgreement/ES/MICINN/MAT2011-24331$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 000063124 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000063124 590__ $$a3.673$$b2013 000063124 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b10 / 78 = 0.128$$c2013$$dQ1$$eT1 000063124 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063124 700__ $$aBlattmann, Ralf 000063124 700__ $$aKohler, Sigmund 000063124 700__ $$aZueco, David 000063124 700__ $$aHänggi, Peter 000063124 773__ $$g15 (2013), 105028 [11 pp]$$pNew j. phys.$$tNEW JOURNAL OF PHYSICS$$x1367-2630 000063124 8564_ $$s510863$$uhttps://zaguan.unizar.es/record/63124/files/texto_completo.pdf$$yVersión publicada 000063124 8564_ $$s88184$$uhttps://zaguan.unizar.es/record/63124/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000063124 909CO $$ooai:zaguan.unizar.es:63124$$particulos$$pdriver 000063124 951__ $$a2017-10-30-13:30:57 000063124 980__ $$aARTICLE
