Probing the Quantum Nature of Gravity through Classical Diffusion
Oliviero Angeli, Sandro Donadi, Giovanni Di Bartolomeo +3
The question of whether gravity is fundamentally quantum remains one of the deepest open problems in modern physics. A recently explored approach consists of testing gravity's abil…
Spontaneous Collapse Models
Matteo Carlesso, Sandro Donadi
Collapse models are phenomenological models introduced to solve the measurement problem in quantum mechanics. They modify the Schrödinger equation by adding non-linear and stochas…
STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
Efficient quantum algorithm to simulate open systems through a single environmental qubit
Giovanni Di Bartolomeo, Michele Vischi, Tommaso Feri +2
We present an efficient algorithm for simulating open quantum systems dynamics described by the Lindblad master equation on quantum computers, addressing key challenges in the fiel…
On the effectiveness of the collapse in the Diósi-Penrose model
Laria Figurato, Marco Dirindin, José Luis Gaona-Reyes +3
The possibility that gravity plays a role in the collapse of the quantum wave function has been considered in the literature, and it is of relevance not only because it would provi…
