We present results of extensive finite-temperature quantum Monte Carlo simulations on a SU(2) symmetric S=1/2 quantum antiferromagnet with four-spin interaction [A. W. Sandvik, Phys. Rev. Lett. 98, 227202 (2007)]. Our simulations, which are free of the sign problem and carried out on lattices containing in excess of 1.6x10(4) spins, indicate that the four-spin interaction destroys the Neel order at an unconventional z=1 quantum critical point, producing a valence-bond solid paramagnet. Our results are consistent with the deconfined quantum criticality scenario.
