Quantum Non-Gaussian State Preparation of Levitated Particles via Time-Dependent Control of Weakly Nonharmonic Hybrid Potentials
Piotr T. Grochowski, Oriol Romero-Isart
Levitated high-mass quantum systems provide access to unprecedented regimes in both fundamental science and technological applications. However, deterministic generation and manipu…
Certifying Macroscopic Quantum Mechanics via Hypothesis Testing with Finite Data
Andreu Riera-Campeny, Patrick Maurer, Oriol Romero-Isart
We address the challenge of certifying quantum behavior with single macroscopic massive particles, subject to decoherence and finite data. We propose a hypothesis testing framework…
Accelerated State Expansion of a Nanoparticle in a Dark Inverted Potential
Gregoire F. M. Tomassi, Daniel Veldhuizen, Bruno Melo +5
While the wave packet of a massive particle grows linearly under free dynamics, it grows exponentially in an inverted harmonic potential, offering a pathway to rapidly increase qua…
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…
