Fast quantum squeezing of a nanomechanical oscillator with an inverted potential
Oscar Schmitt Kremer, Lorenzo Dania, Lukas Novotny +1
Nonclassical states of nano- and micro-mechanical motion enable measurements beyond the standard quantum limit and constitute a key resource for quantum sensing and metrology. The…
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…
High-purity quantum optomechanics at room temperature
Lorenzo Dania, Oscar Schmitt Kremer, Johannes Piotrowski +6
Exploiting quantum effects of mechanical motion, such as backaction evading measurements or squeezing, requires preparation of the oscillator in a high-purity state. The largest st…

Yannick Weiser, Tommaso Faorlin, Lorenz Panzl +6
Levitated dipolar scatterers exhibit exceptional performance as optomechanical systems for observing quantum mechanics at the mesoscopic scale. However, their tendency to scatter l…

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…
Ultra-high quality factor of a levitated nanomechanical oscillator
Lorenzo Dania, Dmitry S. Bykov, Florian Goschin +3
A levitated nanomechanical oscillator under ultra-high vacuum (UHV) is highly isolated from its environment. It has been predicted that this isolation leads to very low mechanical…

Dmitry S. Bykov, Lorenzo Dania, Florian Goschin +1
Cooling the center-of-mass motion of levitated nanoparticles provides a route to quantum experiments at mesoscopic scales. Here we demonstrate three-dimensional sympathetic cooling…
Hybrid electro-optical trap for experiments with levitated particles in vacuum
Dmitry S. Bykov, Maximilian Meusburger, Lorenzo Dania +1
We confine a microparticle in a hybrid potential created by a Paul trap and a dual-beam optical trap. We transfer the particle between the Paul trap and the optical trap at differe…
Position measurement of a levitated nanoparticle via interference with its mirror image
Lorenzo Dania, Katharina Heidegger, Dmitry S. Bykov +3
Interferometric methods for detecting the motion of a levitated nanoparticle provide a route to the quantum ground state, but such methods are currently limited by mode mismatch be…
