Collapse models postulate the existence of intrinsic noise which modifies quantum mechanics and is responsible for the emergence of macroscopic classicality. Assessing the validity of these models is extremely challenging because it is nontrivial to discriminate unambiguously their presence in experiments where other hardly controllable sources of noise compete to the overall decoherence. Here we provide a simple procedure that is able to probe the hypothetical presence of the collapse noise…

Improved Noninterferometric Test of Collapse Models Using Ultracold Cantilevers.

New results from an experiment based on a high-Q cantilever cooled to millikelvin temperatures are reported, which are potentially able to improve the current bounds on the continuous spontaneous localization (CSL) model by 1 order of magnitude.

Nanomechanical test of quantum linearity

Spontaneous wavefunction collapse theories provide the possibility to resolve the measurement problem of quantum mechanics. However, the best experimental tests have been limited by thermal

Can the displacemon device test objective collapse models?

Testing the limits of the applicability of quantum mechanics will deepen our understanding of the universe and may shed light on the interplay between quantum mechanics and gravity. At present there

Detecting continuous spontaneous localization with charged bodies in a Paul trap

Continuous spontaneous localisation (CSL) is a model that captures the effects of a class of extensions to quantum theory which are expected to result from quantum gravity, and is such that

Collapse-induced orientational localization of rigid rotors [Invited]

We show how the ro-translational motion of anisotropic particles is affected by the model of continuous spontaneous localization (CSL), the most prominent hypothetical modification of the Schrodinger

Room temperature test of the continuous spontaneous localization model using a levitated micro-oscillator

The Continuous Spontaneous Localization (CSL) model predicts a tiny break of energy conservation via a weak stochastic force acting on physical systems, which triggers the collapse of the wave

We consider a nanoparticle levitated in a Paul trap in ultrahigh cryogenic vacuum, and look for the conditions which allow for a stringent noninterferometric test of spontaneous collapse models. In

Spatio-orientational decoherence of nanoparticles

Motivated by trapping and cooling experiments with non-spherical nanoparticles, we discuss how their combined rotational and translational quantum state is affected by the interaction with a gaseous

Quantum experiments with microscale particles
