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…
Single-atom detection with a quantum-controlled mechanical oscillator
Maxime Perdriat, Maciej Dziewiecki, Josef-Anton Agner +4
Using supersonic expansion, we create a time-gated, directional beam of Xe atoms with a narrow momentum distribution and detect their collisions with a levitated nanosphere cooled…
Nanomechanical sensor resolving impulsive forces below its zero-point fluctuations
Martynas Skrabulis, Martin Colombano Sosa, Nicola Carlon Zambon +4
The sensitivity of a mechanical transducer is ultimately limited by its inherent quantum fluctuations. Here, we use an optically levitated nanoparticle to measure impulsive forces…
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…
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…
Motional entanglement of remote optically levitated nanoparticles
Nicola Carlon Zambon, Massimiliano Rossi, Martin Frimmer +4
We show how to entangle the motion of optically levitated nanoparticles in distant optical tweezers. The scheme consists in coupling the inelastically scattered light of each parti…
Quantum Delocalization of a Levitated Nanoparticle
Massimiliano Rossi, Andrei Militaru, Nicola Carlon Zambon +4
Every massive particle behaves like a wave, according to quantum physics. Yet, this characteristic wave nature has only been observed in double-slit experiments with microscopic sy…
Feedback cooling a levitated nanoparticle's libration to below 100 phonons
Jialiang Gao, Fons van der Laan, Joanna A. Zielinska +3
Macroscopic rotors are interesting model systems to test quantum theory and for quantum sensing. A promising approach for bringing these systems to the quantum regime is to combine…
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…

Joanna A. Zielińska, Fons van der Laan, Andreas Norrman +3
The field of levitodynamics has made substantial advancements in manipulating the translational and rotational degrees of freedom of levitated nanoparticles. Notably, rotational de…
Escape dynamics of active particles in multistable potentials
Andrei Militaru, Max Innerbichler, Martin Frimmer +3
Rare transitions between long-lived metastable states underlie a great variety of physical, chemical and biological processes. Our quantitative understanding of reactive mechanisms…
