Our research in published in PRL
Our paper "Testing Whether Gravity Acts as a Quantum Entity When Measured" published on Physical Review Letters. The work describe a multi-interferometer experimental setup that can, in principle, reveal the non-classicality of a spatial superposition-sourced gravitational field if an irreducible disturbance is caused by a measurement of gravity. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.133.180201
Our research in published in PRL
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 don't…
QuCoM Steering Committee in Trieste
On 10th September 2024, a QuCoM Steering Committee took place among the PIs of QuCoM partner organization to discuss the development of upcoming deliverables and milestones. The participants also discussed the outcomes of the dissemination strategy and adjustment of the collection of information. The partners viewed the project video that…
QuCoM project meeting in Trieste
On 9th September 2024, a QuCoM scientific meeting took place in Trieste with the aim of updating on progress and defining next steps and new collaborations to achieve the objectives of the project. The following talks were given: Enhancing the deviations from Quantum Mechanics due to Schrödinger-Newton dynamics (Davide Giordano…
Gravity in QuCoM: Project video released
As part of the Dissemination Plan of QuCoM, the Consortium released a project video in May 2024. The scientific question and QuCoM's approach to addressing this question are central to the video. The video aims to illustrate and communicate that QuCoM is a project testing gravity in a new way.…
QuCoM’s first review meeting highlights significant progress of the project
The QuCoM consortium recently concluded its first review meeting on November 20, 2023, achieving significant progress in the various work packages outlined in the agenda.
The meeting, conducted remotely, commenced with a warm welcome by G. Kregar, who initiated the session with an introduction and tour du table, setting a…
Ario and Tommaso join QuCoM
Ario Altamura and Tommaso Feri join QuCoM in the University of Trieste node. We wish them good work!
Our paper “The meaning of redundancy and consensus in quantum objectivity” just appeared on Quantum
A quantum state is said to be objective if multiple observers are able to recover information about the state and agree among themselves. This is in turn possible only if said information was encoded multiple times into the surrounding environment. In this paper, we show how it is not always…
Our paper “Collapse Dynamics Are Diffuse” just appeared on Physical Review Letters
We show that any dynamics collapsing the wave function in space implies diffusion in momentum. This is relevant since it means that, in order to test the validity of thiesse models, and in general of the quantum superposition principle, one can perform experiments, known as “non-interferometric”, which look for this…
EIC Pathfinder grant award to QuCoM
The University of Southampton, the Queen’s University Belfast and the University of Trieste have come together, after a 4.5 year project called TEQ (Horizon H2020), with a new Consortium to present to the European Commission a new project proposal in the frame of the HORIZON-EIC-2021-PATHFINDEROPEN-01-01 call. Together with the University…
