The quantum phase transition point between the insulator and the superfluid phase at unit filling factor of the infinite one‐dimensional Bose‐Hubbard model is numerically computed with a high accuracy. The method uses the infinite system version of the time evolving block decimation algorithm, here tested in a challenging case. We provide also the accurate estimate of the phase transition point at double occupancy.
