Data from: Erasure-cooling, control, and hyper-entanglement of motion in optical tweezers

Coherently controlling the motion of single atoms in optical tweezers
would enable new applications in quantum information science. To
demonstrate this, we first prepare atoms in their motional ground state
using a species-agnostic cooling mechanism that converts motional
excitations into erasures -- errors with a known location. This cooling
mechanism fundamentally outperforms idealized traditional sideband
cooling, which we experimentally demonstrate. By coherently manipulating
the resultant pure motional state, we perform mid-circuit readout and
mid-circuit erasure detection via local shelving into motional
superposition states. We finally entangle the motion of two atoms in
separate tweezers and generate hyper-entanglement by preparing a
simultaneous Bell state of motional and optical qubits, unlocking a large
new class of quantum operations with neutral atoms.
