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

February 18, 2025

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…

Fast and Error-Correctable Quantum RAM
by Francesco Cesa on March 24, 2025 at 9:51 pm
Quantum devices can process data in a fundamentally different way than classical computers. To leverage this potential, many algorithms require the aid of a quantum Random Access Memory (QRAM), i.e. […]
The Unequal Costs of Pollution: Carbon Tax, Inequality, and Redistribution
by Cristiano Cantore on February 28, 2025 at 7:38 pm
This paper studies how household heterogeneity affects the level and cyclical behavior of the optimal carbon tax in a real economy. We demonstrate that an equity-efficiency trade-off arises due to […]
Theoretical Limits of Protocols for Distinguishing Different Unravelings
by J. L. Gaona-Reyes on February 26, 2025 at 4:24 pm
The evolution of an open quantum system is often described by a master equation, which governs the dynamics of the statistical operator. The dynamics of a master equation can be expressed as an […]
Hybrid Classical-Quantum Newtonian Gravity with stable vacuum
by Nicolò Piccione on February 7, 2025 at 3:19 pm
We investigate the Gravitational Poissonian Spontaneous Localization (GPSL) model, a hybrid classical-quantum model in which classical Newtonian gravity emerges from stochastic collapses of the mass […]
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. […]
