      abstract     = {Coherently pumped (Kerr) solitons in an ideal optical
                      microcavity are expected to undergo random quantum motion
                      thatdetermines fundamental performance limits in
                      applications ofthe soliton microcombs1. Here this random
                      walk and its impacton Kerr soliton timing jitter are studied
                      experimentally. Thequantum limit is discerned by measuring
                      the relative positionof counter-propagating solitons2. Their
                      relative motion features weak interactions and also presents
                      common-mode suppression of technical noise, which typically
                      hides the quantumfluctuations. This is in contrast to
                      co-propagating solitons,which are found to have relative
                      timing jitter well below thequantum limit of a single
                      soliton on account of strong correlation of their mutual
                      motion. Good agreement is found betweentheory and
                      experiment. The results establish the fundamentallimits to
                      timing jitter in soliton microcombs and provide newinsights
                      on multisoliton physics.},
