  We investigate the relevance of quantum gravity during inflation to address
the Hubble tension that arises from Planck 2018 and SH0ES data sets. We show
that the effect of quantum gravity during inflation can increase the rate of
change of $H_0$, thereby accounting for a wide range of observed $H_0$.
Further, we show that due to the quantum gravity effect on inflation, the
temperature at the onset of reheating can be lower than the standard case,
causing delays in the reheating process. The role of quantum gravity is
inevitable in settling the Hubble tension. The results of the present study may
find use in resolving the Hubble tension, in validating inflationary model and
quantum gravity.
