We work in quantum mechanics and its foundations: the measurement problem, the meaning of the wave function, entaglement and nonlocality, the quantum-to-classical transition, the relation between quantum theory and relativity/gravity.

Angelo Bassi Discusses the Foundations of Quantum Mechanics on Sky TG24’s “Science, please” Podcast

2 days ago

In a recent episode of Science, please, the Sky TG24 podcast that explores major scientific questions, Angelo Bassi was invited to discuss the foundations of quantum mechanics and the challenges it presents. The conversation focused on the measurement problem, which questions how and when quantum systems transition from a superposition of states to a definite outcome.…

Exploring the Accuracy of Interferometric Quantum Measurements under Conservation Laws, our research in PRL

February 3, 2025

We study a modified version (arguably within reach of present technology) of a typical interferometric measurement scheme so that energy conservation enters in a non-trivial way. In such a case, the measurement accuracy is limited by fundamental bounds due to energy conservation. We characterize the measurement error in relation to…

Angelo Bassi publishes on PRL

September 11, 2024

Our paper "X-Ray Emission from Atomic Systems Can Distinguish between Prevailing Dynamical Wave-Function Collapse Models" published on Physical Review Letters. The work proposes a novel method to test collapse models using X-ray emissions from atomic systems. These models challenge the standard quantum theory by offering explanations for why quantum superpositions…

Newtonian Gravity from a Poissonian Spontaneous Collapse Model
by Nicolò Piccione on February 7, 2025 at 3:19 pm
The Tilloy-Di\'osi (TD) prescription allows to turn any Markovian spontaneous collapse model that can be formally regarded as a continuous measurement process of the mass density into a hybrid […]
Hierarchical generation and design of quantum codes for resource-efficient loss-tolerant quantum communications
by Francesco Cesa on January 30, 2025 at 7:00 pm
We develop novel protocols for generating loss-tolerant quantum codes; these are central for safeguarding information against qubit losses, with most crucial applications in quantum communications. […]
Exploring the Effects of Mass Dependence in Spontaneous Collapse Models
by Nicolò Piccione on January 29, 2025 at 1:14 pm
The Continuous Spontaneous Localization (CSL) model predicts a quadratic mass scaling of its effects but a linear scaling might be more natural according to some Poissonian spontaneous collapse […]
Positivity and Entanglement in Markovian Open Quantum Systems and Hybrid Classical-Quantum Theories of Gravity
by Oliviero Angeli on January 27, 2025 at 5:53 pm
Markovian master equations underlie many areas of modern physics and, despite their apparent simplicity, they encode a rich and complex dynamics which is still under active research. We identify a […]
Probing the Quantum Nature of Gravity through Diffusion
by Oliviero Angeli on January 22, 2025 at 5:22 pm
The quest to determine whether gravity is quantum has challenged physicists since the mid 20th century, due to the impracticability of accessing the Planck scale, where potential quantum gravity […]
