Experimentally feasible computational advantage from quantum superposition of gate orders
Martin J. Renner, Časlav Brukner
In an ordinary quantum algorithm the gates are applied in a fixed order on the systems. The introduction of indefinite causal structures allows to relax this constraint and control…
High-resolution detection of neutral oxygen and non-LTE effects in the atmosphere of KELT-9b
Francesco Borsa, Luca Fossati, Tommi Koskinen +2
Oxygen is a constituent of many of the most abundant molecules detected in exoplanetary atmospheres and a key ingredient for tracking how and where a planet formed. In particular,…
Accurate determination of the scattering length of erbium atoms
A. Patscheider, L. Chomaz, G. Natale +7
An accurate knowledge of the scattering length is fundamental in ultracold quantum gas experiments and essential for the characterisation of the system as well as for a meaningful…
Controlling wave-particle duality with quantum entanglement
Kai Wang, Daniel R. Terno, Caslav Brukner +2
Wave-particle duality and entanglement are two fundamental characteristics of quantum mechanics. All previous works on experimental investigations in wave{particle properties of si…
Collective bosonic effects in an array of transmon devices
Tuure Orell, Maximilian Zanner, Mathieu L. Juan +5
Multiple emitters coherently interacting with an electromagnetic mode give rise to collective effects such as correlated decay and coherent exchange interaction, depending on the s…
The GAPS Programme at TNG. XXXII. The revealing non-detection of metastable HeI in the atmosphere of the hot Jupiter WASP-80b
L. Fossati, G. Guilluy, I. F. Shaikhislamov +38
The hot Jupiter WASP-80b has been identified as a possible excellent target for detecting and measuring HeI absorption in the upper atmosphere. We observed 4 primary transits of WA…
Controlling long ion strings for quantum simulation and precision measurements
Florian Kranzl, Manoj K. Joshi, Christine Maier +4
Scaling a trapped-ion based quantum simulator to a large number of ions creates a fully-controllable quantum system that becomes inaccessible to numerical methods. When highly anis…
Machine learning discovery of new phases in programmable quantum simulator snapshots
Cole Miles, Rhine Samajdar, Sepehr Ebadi +7
Machine learning has recently emerged as a promising approach for studying complex phenomena characterized by rich datasets. In particular, data-centric approaches lend to the poss…
Squeezing Quantum Many-Body Scars
Bennet Windt, Hannes Pichler
We develop an analytical approach for the description of quantum many-body scars in PXP models. We show that the scarred dynamics in the PXP model on a complete bipartite graph can…
Hyperfine spectroscopy of antihydrogen, hydrogen, and deuterium
Eberhard Widmann
The prospects of tests of CPT symmetry using precision spectroscopy of antihydrogen are discussed with special emphasis on the ground-state hyperfine structure, a measurement of wh…
Atmospheric mass loss and stellar wind effects in young and old systems II: Is TOI-942 the past of TOI-421 system?
Daria Kubyshkina, Aline A. Vidotto, Carolina Villarreal D'Angelo +3
The two planetary systems TOI-942 and TOI-421 share many similar characteristics, apart from their ages (50~Myr and 9~Gyr). Each of the stars hosts two sub-Neptune-like planets at…
Atmospheric mass loss and stellar wind effects in young and old systems I: comparative 3D study of TOI-942 and TOI-421 systems
Daria Kubyshkina, Aline A. Vidotto, Carolina Villarreal D'Angelo +3
At young ages, when radiation from the host star is high, and the planet is hot and inflated after formation, planetary atmospheric mass loss can be extremely strong compared to ol…
A quantum processor based on coherent transport of entangled atom arrays
Dolev Bluvstein, Harry Levine, Giulia Semeghini +9
The ability to engineer parallel, programmable operations between desired qubits within a quantum processor is central for building scalable quantum information systems. In most st…
4H-Silicon Carbide as particle detector for high-intensity ion beams
Manuel Christanell, Maximilian Tomaschek, Thomas Bergauer
In ion cancer therapy, high-intensity ion beams are used to treat tumors by taking advantage of the Bragg-Peak. Typical ion therapy centers use particle rates up to ions/…
Experimental Bayesian calibration of trapped ion entangling operations
Lukas Gerster, Fernando Martínez-García, Pavel Hrmo +7
The performance of quantum gate operations is experimentally determined by how correct operational parameters can be determined and set, and how stable these parameters can be main…
The inverse source problem for the wave equation revisited: A new approach
Mourad Sini, Haibing Wang
The inverse problem of reconstructing a source term from boundary measurements, for the wave equation, is revisited. We propose a novel approach to recover the unknown source throu…
The impact of intrinsic magnetic field on the absorption signatures of elements probing the upper atmosphere of HD209458b
M. L. Khodachenko, I. F. Shaikhislamov, H. Lammer +4
The signs of an expanding atmosphere of HD209458b have been observed with far-ultraviolet transmission spectroscopy and in the measurements of transit absorption by metastable HeI.…
Temporal entanglement, quasiparticles and the role of interactions
Giacomo Giudice, Giuliano Giudici, Michael Sonner +4
In quantum many-body dynamics admitting a description in terms of non-interacting quasiparticles, the Feynman-Vernon influence matrix (IM), encoding the effect of the system on the…
Quantum reference frames for an indefinite metric
Anne-Catherine de la Hamette, Viktoria Kabel, Esteban Castro-Ruiz +1
The current theories of quantum physics and general relativity on their own do not allow us to study situations in which the gravitational source is quantum. Here, we propose a str…
Dark Freeze-out Cogenesis
Xiaoyong Chu, Yanou Cui, Josef Pradler +1
We propose a new mechanism where a multi-component dark sector generates the observed dark matter abundance and baryon asymmetry and thus addresses the coincidence between the two.…
