Simulation algorithms, Floquet phenomena and superconducting qubits
… topics that span the abstraction stack of quantum computing: from physical properties of superconducting qubits to computational properties of algorithms for quantum simulation. In the introduction, we begin by reviewing the circuit model of quantum computing. We then introduce circuit …

Fluctuation-mediated interactions of atoms and surfaces on a mesoscopic scale
Thermal and quantum fluctuations of the electromagnetic near field of atoms and macroscopic bodies play a key role in quantum electrodynamics (QED), as in the Lamb shift. They lead, e.g., to atomic level shifts, dispersion interactions (Van der Waals-Casimir-Polder interactions), and state …

The QED beta-Function: A First Principles Derivation
Quantum electrodynamics (QED) is a quantum-relativistic theory for electromagnetism. It is among the most successful quantum field theories, which collectively describe the dynamics of elementary particles at high energies. Unfortunately, the dynamical expressions for interacting theories do not …

Isospin Violating Hadronic Mass Splittings using Lattice QCD+QED
… century was the development of the theories of quantum chromodynamics (QCD) and quantum electrodynamics (QED), which reveal an even deeper layer of structure than the atom and the nucleon. We use the non-perturbative method of lattice QCD+QED to make precision estimates of the masses and mass …

ADVANCEMENTS IN PDFS DETERMINATION: INCORPORATION OF QED EFFECTS AND NEW THEORETICAL IMPROVEMENTS IN A MODERN DEEP LEARNING FRAMEWORK
… data. Such effects are the inclusion of Quantum Electrodynamics (QED) corrections, the inclusion of the so-called missing higher orders uncertainties (MHOUs) and the inclusion of approximate next-to-next-to-next-to-leading order contributions (aN$^3$LO). This work aims to overcome the …

Waveguide Quantum Electrodynamics with Superconducting Qubits
Experiments utilizing quantum optics have progressed rapidly in last few decades, particularly in the context of quantum computation, simulation, and communication. Early work in this field focused on implementations of cavity quantum electrodynamics (QED), where atoms, either natural or …

Quantum electrodynamics and fundamental constants
… requires a careful study of the effects from quantum electrodynamics (QED) on the interaction between the electron and the nucleus.</p> <p>The two theoretical approaches for the evaluation of QED corrections are presented and discussed. Due to the presence of two energy scales from the binding …

Experimental Studies of Radiation Reaction and Photon-Photon Collisions in Ultrahigh Intensity Regimes
Quantum Electrodynamics (QED), in the perturbative limit has proved to be one of the most robust theoretical frameworks in physics, exhibiting vast calculation potential and being corroborated repeatedly by experimental observations. Nonetheless, there are still some open questions with regards to …

Radiation generation and high-field physics phenomena in ultra-intense laser-solid interactions
… fields have sufficiently strong magnitudes that quantum electrodynamics (QED) effects play a significant role in the interaction.;There are two key effects which will be considered within the context of this thesis. The first is prolific production of high energy radiation from electrons that are …

Casimir Force in Non-Planar Geometric Configurations
The Casimir force for charge-neutral, perfect conductors of non-planar geometric configurations have been investigated. The configurations were: (1) the plate-hemisphere, (2) the hemisphere-hemisphere and (3) the spherical shell. The resulting Casimir forces for these physical arrangements have …
