Dimensional Reduction of Gauge Theories and Quantum Simulations
We derive and discuss one- and two-dimensional models for classical electromagnetism by making use of Hadamard’s method of descent. Low-dimensional electromagnetism is conceived as a... Read More
Reflected entropy in holography and beyond
The reflected entropy is a measure of correlation introduced in the context of holography, where it has a simple and compelling geometric interpretation. In addition... Read More
Quantum Computation for Quantum Field Theories and Nuclear Physics
Theoretical predictions of the properties and dynamics of quantum many-body systems of importance to nuclear physics research, from field theories to dense and/or non-equlibrium matter... Read More
Quantum (Inspired) Algorithms for Collider Physics
Particle physicists have developed numerous classical algorithms to process data from high-energy particle collisions. Computational efficiency is an important criteria for selecting collider data analysis strategies,... Read More
Exploring applications of quantum computing at CERN
The computing and storage requirements for the upcoming High-Luminosity Large Hadron Collider programme represent a considerable challenge for CERN and the High Energy Physics community... Read More
From tensor networks to quantum computations of lattice field theories
We will explore U(1) lattice gauge theories with topological terms in D=1,2 and 3 spatial dimensions. For D=1, we scrutinize mass perturbation theory at small... Read More
Engineering local U(1) symmetry in artificial systems
In this talk, I will present our work on analog simulators of a U(1) gauge theory in one spatial dimension. To engineer the local gauge... Read More
Towards simulating 2D effects in lattice gauge theories on a quantum computer
Gauge theories are the most successful theories for describing nature at its fundamental level, but obtaining analytical or numerical solutions often remains a challenge. We... Read More
The Fermilab Quantum Science and Technology Program
Quantum Science and Technology (QS&T) exploits quantum properties of physical systems for acquiring, communicating, and processing information beyond classical capabilities. Successful applications of QS&T could... Read More
