Query: Efficient collisional blockade loading of single atom into a tight
  microtrap   We show that controlled inelastic collisions can improve the single atom
loading efficiency in the collisional blockade regime of optical microtraps. A
collisional loss process where only one of the colliding atoms are lost,
implemented during loading, enables us to kick out one of the atoms as soon as
a second atom enters the optical microtrap. When this happens faster than the
pair loss, which has limited the loading efficiency of previous experiments to
about 50%, we experimentally observe an enhancement to 80%. A simple analytical
theory predicts the loading dynamics. Our results opens up an efficient and
fast route for loading individual atoms into optical tweezers and arrays of
microtraps that are too tight for easy implementation of the method reported in
[1,2]. The loading of tight traps with single atoms is a requirement for their
applications in future experiments in quantum information processing and
few-body physics.
