Query: Entanglement transport and a nanophotonic interface for atoms in optical
  tweezers   The realization of an efficient quantum optical interface for multi-qubit
systems is an outstanding challenge in science and engineering. Using two atoms
in individually-controlled optical tweezers coupled to a nanofabricated
photonic crystal cavity, we demonstrate entanglement generation, fast
non-destructive readout, and full quantum control of atomic qubits. The
entangled state is verified in free space after being transported away from the
cavity by encoding the qubits into long-lived states and using dynamical
decoupling. Our approach bridges quantum operations at an optical link and in
free space with a coherent one-way transport, potentially enabling an
integrated optical interface for atomic quantum processors.
