50-km fiber interferometer for testing gravitational signatures in quantum interference
Haocun Yu, Dorotea Macri, Thomas Morling +10
Quantum mechanics and general relativity are the foundational pillars of modern physics, yet experimental tests that combine the two frameworks remain rare. Measuring optical phase…
Robust certification of non-projective measurements: theory and experiment
Raphael Brinster, Peter Tirler, Shishir Khandelwal +7
Determining the conditions under which positive operator-valued measures (POVMs), the most general class of quantum measurements, outperform projective measurements remains a chall…
Absence of measurement- and unraveling-induced entanglement transitions in continuously monitored one-dimensional free fermions
Clemens Niederegger, Tatiana Vovk, Elias Starchl +1
Continuous monitoring of one-dimensional free fermionic systems can generate phenomena reminiscent of quantum criticality, such as logarithmic entanglement growth, algebraic correl…
Gravitational and other shifts of whispering gallery and gravitational state interference patterns of light neutral particles
V. V. Nesvizhevsky, J. A. Pioquinto, K. Schreiner +7
We discuss small shifts in the interference patterns of gravitational and whispering gallery quantum states that can be observed with neutrons, atoms, antiatoms, muonium, positroni…
Deconfined quantum criticality on a triangular Rydberg array
Lisa Bombieri, Torsten V. Zache, Gabriele Calliari +3
Fluctuations can drive continuous phase transitions between two distinct ordered phases -- so-called deconfined quantum critical points (DQCPs) -- which lie beyond the Landau-Ginzb…
atommovr: An open-source simulation framework for rearrangement in atomic arrays
Nikhil K Harle, Bo-Yu Chen, Bob Bao +1
The task of atom rearrangement has emerged in the last decade as a fundamental building block in the development of neutral atom-based quantum processors. As such processors grow t…
Learning mixed quantum states in large-scale experiments
Matteo Votto, Marko Ljubotina, Cécilia Lancien +5
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shado…
Violation of Bell Inequality with Unentangled Photons
Kai Wang, Zhaohua Hou, Kaiyi Qian +6
Violation of local realism via Bell inequality - a profound and counterintuitive manifestation of quantum theory that conflicts with the prediction of local realism - is viewed to…
Asymmetric two-photon response of an incoherently driven quantum emitter
Lennart Jehle, Lena M. Hansen, Patrik I. Sund +7
Quantum emitters promise to emit exactly one photon with high probability when pumped by a laser pulse. However, even in ideal systems, re-excitation during a laser pulse causes th…
Multi-photon emission from a resonantly pumped quantum dot
Francesco Giorgino, Patrik Zahálka, Lennart Jehle +4
Resonance fluorescence of natural or artificial atoms constitutes a prime method for generating non-classical light. While most efforts have focused on producing single-photons, mu…
Coarse-grained quantum thermodynamics: Observation-dependent quantities, observation-independent laws
Giulia Rubino, Časlav Brukner, Gonzalo Manzano
In both classical and quantum thermodynamics, physical quantities are typically assigned objective values defined independently of our observations. We then refer to the 'work perf…
Gravity-mediated entanglement via infinite-dimensional systems
Stefan L. Ludescher, Leon D. Loveridge, Thomas D. Galley +1
There has been a wave of recent interest in detecting the quantum nature of gravity with table-top experiments that witness gravitationally mediated entanglement. Central to these…
Certifying Macroscopic Quantum Mechanics via Hypothesis Testing with Finite Data
Andreu Riera-Campeny, Patrick Maurer, Oriol Romero-Isart
We address the challenge of certifying quantum behavior with single macroscopic massive particles, subject to decoherence and finite data. We propose a hypothesis testing framework…
Certified randomness from quantum speed limits
Caroline L. Jones, Albert Aloy, Gerard Higgins +1
Quantum speed limits are usually regarded as fundamental restrictions, constraining the amount of computation that can be achieved within some given time and energy. Complementary…
Cooling a Qubit using n Others
Jake Xuereb, Benjamin Stratton, Alberto Rolandi +3
In the task of unitarily cooling a quantum system with access to a larger quantum system, known as the machine or reservoir, how does the structure of the machine impact an agent's…
Observation of Genuine High-dimensional Multi-partite Non-locality in Entangled Photon States
Xiao-Min Hu, Cen-Xiao Huang, Nicola d'Alessandro +10
Quantum information science has leaped forward with the exploration of high-dimensional quantum systems, offering greater potential than traditional qubits in quantum communication…
Bayesian Frequency Metrology with Optimal Ramsey Interferometry in Optical Atomic Clocks
Timm Kielinski, Klemens Hammerer
Frequency metrology is a cornerstone of modern precision measurements and optical atomic clocks have emerged as the most precise measurement devices. In this progress report, we ex…

Ludmila Viotti, Marcus Huber, Rosario Fazio +1
Understanding different aspects of time is at the core of many areas in theoretical physics. Minimal models of continuous stochastic and quantum clocks have been proposed to explor…
Subjective nature of path information in quantum mechanics
Xinhe Jiang, Armin Hochrainer, Jaroslav Kysela +4
Common sense suggests that a particle must have a definite origin if its full path information is available. In quantum mechanics, the knowledge of path information is captured thr…
