Query: Low-entropy states of neutral atoms in polarization-synthesized optical
  lattices   We create low-entropy states of neutral atoms by utilizing a conceptually new
optical-lattice technique that relies on a high-precision, high-bandwidth
synthesis of light polarization. Polarization-synthesized optical lattices
provide two fully controllable optical lattice potentials, each of them
confining only atoms in either one of the two long-lived hyperfine states. By
employing one lattice as the storage register and the other one as the shift
register, we provide a proof of concept using four atoms that selected regions
of the periodic potential can be filled with one particle per site. We expect
that our results can be scaled up to thousands of atoms by employing a
atom-sorting algorithm with logarithmic complexity, which is enabled by
polarization-synthesized optical lattices. Vibrational entropy is subsequently
removed by sideband cooling methods. Our results pave the way for a bottom-up
approach to creating ultralow-entropy states of a many-body system.
