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…
