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…
Shot-to-shot noise cancellation for parametric oscillators
Martynas Skrabulis, Martin Colombano Sosa, Nicola Carlon Zambon +4
Powerful approaches to squeeze the motional state of a harmonic oscillator rely on the stepwise modulation of its resonance frequency. Such protocols can be limited by forces that…
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…

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…

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

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…

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…
