Quantum optics with giant atoms -- the first five years
Anton Frisk Kockum
In quantum optics, it is common to assume that atoms can be approximated as point-like compared to the wavelength of the light they interact with. However, recent advances in exper…
Deep Q-learning decoder for depolarizing noise on the toric code
David Fitzek, Mattias Eliasson, Anton Frisk Kockum +1
We present an AI-based decoding agent for quantum error correction of depolarizing noise on the toric code. The agent is trained using deep reinforcement learning (DRL), where an a…
Jacob Bekenstein's Universes: From Black Holes to Modified Theories of Gravity
Ofer Lahav
Jacob Bekenstein's pioneering contributions to the foundations of Gravity cover a broad range of scales, from Black Holes to the entire Universe. He is well known as the father of…
Phononic loss in superconducting resonators on piezoelectric substrates
Marco Scigliuzzo, Laure E. Bruhat, Andreas Bengtsson +3
We numerically and experimentally investigate the phononic loss for superconducting resonators fabricated on a piezoelectric substrate. With the help of finite element method simul…
Ultracompact H II Regions with Extended Emission: The Complete View
Eduardo de la Fuente, Alicia Porras, Miguel A. Trinidad +5
In this paper we present the results of a morphological study performed on a sample of 28 ultracompact \hiirs~located near extended free-free emission, using radio continuum observ…
Large responsivity of graphene radiation detectors with thermoelectric readout
A. Yurgens
Simple estimations show that the thermoelectric readout in graphene radiation detectors can be extremely effective even for graphene with modest charge-carrier mobility ~1000 cm^2/…
Ultrastrong coupling between nanoparticle plasmons and cavity photons at ambient conditions
Denis G. Baranov, Battulga Munkhbat, Elena Zhukova +6
Ultrastrong coupling is a distinct regime of electromagnetic interaction that enables a rich variety of intriguing physical phenomena. Traditionally, this regime has been reached b…
A Flipped Classroom Approach to Teaching Empirical Software Engineering
Lucas Gren
Contribution: A flipped classroom approach to teaching empirical software engineering increases student learning by providing more time for active learning in class. Background: Th…
End-to-End Learning of Geometrical Shaping Maximizing Generalized Mutual Information
Kadir Gümüs, Alex Alvarado, Bin Chen +2
GMI-based end-to-end learning is shown to be highly nonconvex. We apply gradient descent initialized with Gray-labeled APSK constellations directly to the constellation coordinates…
Large Easy Axis Anisotropy in the One-Dimensional Magnet BaMo(PO)
Aly H. Abdeldaim, Danis I. Badrtdinov, Alexandra S. Gibbs +9
We present an extensive experimental and theoretical study on the low-temperature magnetic properties of the monoclinic anhydrous alum compound BaMo(PO). The magnetic susce…
Ab initio models of atomic nuclei: challenges and new ideas
Andreas Ekström
This review presents some of the challenges in constructing models of atomic nuclei starting from theoretical descriptions of the strong interaction between nucleons. The focus is…
Characterizing decoherence rates of a superconducting qubit by direct microwave scattering
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +8
We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its o…
Defects from phonons: Atomic transport by concerted motion in simple crystalline metals
Erik Fransson, Paul Erhart
Point defects play a crucial role in crystalline materials as they do not only impact the thermodynamic properties but are also central to kinetic processes. While they are necessa…
Do AGN really suppress star formation?
C. M. Harrison, D. M. Alexander, D. J. Rosario +2
Active galactic nuclei (AGN) are believed to regulate star formation inside their host galaxies through "AGN feedback". We summarise our on-going study of luminous AGN (z~0.2-3; L_…
Waveguide Quantum Electrodynamics with Giant Superconducting Artificial Atoms
Bharath Kannan, Max Ruckriegel, Daniel Campbell +14
Models of light-matter interactions typically invoke the dipole approximation, within which atoms are treated as point-like objects when compared to the wavelength of the electroma…
Wideband 67-116 GHz receiver development for ALMA Band 2
P. Yagoubov, T. Mroczkowski, V. Belitsky +43
ALMA has been operating since 2011, but has not yet been populated with the full suite of intended frequency bands. In particular, ALMA Band 2 (67-90 GHz) is the final band in the…
Applying the Quantum Approximate Optimization Algorithm to the Tail Assignment Problem
Pontus Vikstål, Mattias Grönkvist, Marika Svensson +3
Airlines today are faced with a number of large scale scheduling problems. One such problem is the tail assignment problem, which is the task of assigning individual aircraft to a…
Improved success probability with greater circuit depth for the quantum approximate optimization algorithm
Andreas Bengtsson, Pontus Vikstål, Christopher Warren +12
Present-day, noisy, small or intermediate-scale quantum processors---although far from fault-tolerant---support the execution of heuristic quantum algorithms, which might enable a…
Experimentally Calibrated Kinetic Monte Carlo Model Reproduces Organic Solar Cell Current-Voltage Curve
Sebastian Wilken, Tanvi Upreti, Armantas Melianas +5
Kinetic Monte Carlo (KMC) simulations are a powerful tool to study the dynamics of charge carriers in organic photovoltaics. However, the key characteristic of any photovoltaic dev…
Poisson Multi-Bernoulli Mixtures for Sets of Trajectories
Karl Granström, Lennart Svensson, Yuxuan Xia +2
The Poisson Multi-Bernoulli Mixture (PMBM) density is a conjugate multi-target density for the standard point target model with Poisson point process birth. This means that both th…
5G Positioning and Mapping with Diffuse Multipath

Atomic responses to general dark matter-electron interactions
Riccardo Catena, Timon Emken, Nicola A. Spaldin +1
In the leading paradigm of modern cosmology, about 80% of our Universe's matter content is in the form of hypothetical, as yet undetected particles. These do not emit or absorb rad…
