The Quantum Approximate Optimization Algorithm performance with low entanglement and high circuit depth

Rishi Sreedhar, Pontus Vikstål, Marika Svensson +3

Variational quantum algorithms constitute one of the most widespread methods for using current noisy quantum computers. However, it is unknown if these heuristic algorithms provide…

Non-Markovian steady states of a driven two-level system

Andreas Ask, Göran Johansson

We show that an open quantum system in a non-Markovian environment can reach steady states that it cannot reach in a Markovian environment. As these steady states are unique for th…

Synthesizing electromagnetically induced transparency without a control field in waveguide QED using small and giant atoms

Andreas Ask, Yao-Lung L. Fang, Anton Frisk Kockum

The absorption of photons in a three-level atom can be controlled and manipulated by applying a coherent drive at one of the atomic transitions. The situation where the absorption…

Breaking time-reversal and translational symmetry at edges of -wave superconductors: microscopic theory and comparison with quasiclassical theory

N. Wall Wennerdal, A. Ask, P. Holmvall +2

We report results of a microscopic calculation of a second-order phase transition into a state breaking time-reversal and translational invariance along pair-breaking edges of -…

Engineering the Level Structure of a Giant Artificial Atom in Waveguide Quantum Electrodynamics

A. M. Vadiraj, Andreas Ask, T. G. McConkey +4

Engineering light-matter interactions at the quantum level has been central to the pursuit of quantum optics for decades. Traditionally, this has been done by coupling emitters, ty…
