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…
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…
Numerical Simulation of Large-Scale Nonlinear Open Quantum Mechanics
Marc Roda-Llordes, Davide Candoli, Piotr T. Grochowski +5
We introduce a numerical method to simulate nonlinear open quantum dynamics of a particle in situations where its state undergoes significant expansion in phase space while generat…
