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…

A geometric phase approach to quark confinement from stochastic gauge-geometry flows

Torsten Asselmeyer-Maluga, Antonino Marciano, Roman Pasechnik +1

We apply a stochastic version of the geometric (Ricci) flow, complemented with the stochastic flow of the gauge Yang--Mills sector, in order to seed the chromo-magnetic and chromo-…

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…
