We analyze the performance of a scheme that embeds careful time-control of trapping potentials. The feasibility of our proposal, which is close to experimental state-of-the-art, makes it a valuable tool for quantum state engineering.

• Abstract: Squeezing is a crucial resource for quantum information processing and quantum sensing. In levitated nanomechanics, squeezed states of motion can be generated via temporal control of the trapping frequency of a massive particle. However, the amount of achievable squeezing typically suffers from detrimental environmental effects. We analyze the performance of a scheme that, by embedding careful time-control of trapping potentials and fully accounting for the most relevant sources of noise -- including measurement backaction -- achieves significant levels of mechanical squeezing. The feasibility of our proposal, which is close to experimental state-of-the-art, makes it a valuable tool for quantum state engineering.

  We demonstrate time-of-flight measurements for an ultracold levitated nanoparticles and reveal its velocity for the translational motion brought to the quantum ground state. We discover that the velocity distributions obtained with repeated release-and-recapture measurements are significantly broadened via librational motions of the nanoparticles.

  We present an experimental proposal for the rapid preparation of the center of mass of a levitated particle in a macroscopic quantum state. This state is prepared by letting the particle evolve in a static double-well potential after a sudden switchoff of the harmonic trap. We highlight the possibility of using two particles, one evolving in each potential well, to mitigate the impact of collective sources of noise and decoherence.

  We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
