Amplituhedra for generic quantum processes via the TQNN representation of UQC
Chris Fields, James F. Glazebrook, Antonino Marcianò +1
We study the relationship between computation and scattering both operationally (hence phenomenologically) and formally. We develop a representation of universal quantum computatio…
Experimental exclusion of a generalized Károlyházy gravity-induced decoherence model
Nicola Bortolotti, Kristian Piscicchia, Matthias Laubenstein +4
We report new experimental constraints on the generalized version of the gravity-induced decoherence model originally proposed by Károlyházy. Using data collected by the VIP Coll…
Operational protocols cannot certify classicality
Chris Fields, James F. Glazebrook, Antonino Marcianò +1
The existence and practical utility of operational protocols that certify entanglement raises the question of whether operational protocols exist that certify the absence of entang…
Whether a quantum computation employs nonlocal resources is operationally undecidable
Chris Fields, James F. Glazebrook, Antonino Marciano +1
Computational complexity characterizes the usage of spatial and temporal resources by computational processes. In the classical theory of computation, e.g. in the Turing Machine mo…
ER = EPR is an operational theorem
Chris Fields, James F. Glazebrook, Antonino Marciano +1
We show that in the operational setting of a two-agent, local operations, classical communication (LOCC) protocol, Alice and Bob cannot operationally distinguish monogamous entangl…
Deep Neural Networks as the Semi-classical Limit of Topological Quantum Neural Networks: The problem of generalisation
Antonino Marciano, Emanuele Zappala, Tommaso Torda +5
Deep Neural Networks miss a principled model of their operation. A novel framework for supervised learning based on Topological Quantum Field Theory that looks particularly well su…
