We study the influence of Ohmic dissipation on the random transverse-fieldIsing chain by means of large-scale Monte-Carlo simulations. To this end, wefirst map the Hamiltonian onto a classical Ising model with long-range$1/\tau^2$ interaction in the time-like direction. We then apply the highlyefficient cluster algorithm proposed by Luijten and Bl\"ote for system withlong-range interactions. Our simulations show that Ohmic dissipation destroysthe infinite-randomness quantum critical point of the dissipationless system.Instead, the quantum phase transition between the paramagnetic andferromagnetic phases is smeared. We compare our results to recent predictionsof a strong-disorder renormalization group approach, and we discussgeneralizations to higher dimensions as well as experiments.
