Shot-to-shot displacement noise in state-expansion protocols with inverted potentials
Giuseppe Paolo Seta, Louisiane Devaud, Lorenzo Dania +2
Optically levitated nanoparticles are promising candidates for the generation of macroscopic quantum states of mechanical motion. Protocols to generate such states expose the parti…
Trap-to-trap free falls with an optically levitated nanoparticle
M. Luisa Mattana, Nicola Carlon Zambon, Massimiliano Rossi +4
We perform free-fall experiments with a charge-neutral, optically levitated nanoparticle. This is achieved using an optical tweezer that can be rapidly toggled on and off and verti…
State Expansion of a Levitated Nanoparticle in a Dark Harmonic Potential
Eric Bonvin, Louisiane Devaud, Massimiliano Rossi +7
Levitated nanoparticles in vacuum are prime candidates for generating macroscopic quantum superposition states of massive objects. Most protocols for preparing these states necessi…
Hybrid Paul-optical trap with large optical access for levitated optomechanics
Eric Bonvin, Louisiane Devaud, Massimiliano Rossi +7
We present a hybrid trapping platform that allows us to levitate a charged nanoparticle in high vacuum using either optical fields, radio-frequency fields, or a combination thereof…
