Using the dynamical polaron ansatz and matrix-product state simulations, we discuss the case where both light-matter g coupling and system-bath interaction are in the ultra-strong-coupling regime. We provide a critical g for the onset of Rabi oscillations. Besides, we demonstrate that the qubit is dressed by the cavity and dissipation. Such a dressing governs the dynamics and, thus, it can be measured. Finally, we sketch an implementation for our theoretical ideas within circuit QED technology. 000077181 536__ $$9info:eu-repo/grantAgreement/ES/DGA/CAM PRICYT/QUITEMAD+S2013-CE-2801$$9info:eu-repo/grantAgreement/ES/DGA/Q-MAD$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2015-70856-P$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2017-88358-C3-1-R$$9info:eu-repo/grantAgreement/EUR/QUANTERA/SUMO 000077181 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000077181 590__ $$a2.777$$b2019 000077181 591__ $$aPHYSICS, ATOMIC, MOLECULAR & CHEMICAL$$b12 / 36 = 0.333$$c2019$$dQ2$$eT2 000077181 591__ $$aOPTICS$$b31 / 97 = 0.32$$c2019$$dQ2$$eT1 000077181 592__ $$a1.416$$b2019 000077181 593__ $$aAtomic and Molecular Physics, and Optics$$c2019$$dQ1 000077181 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000077181 700__ $$aGarcía-Ripoll, J. 000077181 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
