Fundamental impossibility of a superradiant neutrino laser
Yu-Kun Lu, Hanzhen Lin, Wolfgang Ketterle·Oct 24, 2025
Here we address the fundamental question whether an idealized system of $N$ atoms will show collective behavior and superradiance when it emits fermions instead of photons. We show that the maximum emission is $\propto N$ and not $\propto N^2$ which ...
Can Bose-Einstein condensates enhance radioactive decay?
Hanzhen Lin, Yukun Lu, Wolfgang Ketterle·Oct 24, 2025
This paper lays out the principles of how Bose-Einstein condensates can modify radioactive decay. We highlight the challenges of many modes and short coherence times due to the $\approx$ MeV energies of the emitted radiation. Recent proposals for gam...
Energy storage in a continuous-variable quantum battery with nonlinear coupling
C. A. Downing, M. S. Ukhtary·Oct 24, 2025
In the quantum world, the process of energy storage can be enhanced thanks to various nonclassical phenomena. This inspiring fact suggests quantum batteries as plausible sources of power for future quantum devices, at least in principle. However, the...
Analytical determination of multi-time correlation functions in quantum chaotic systems
Yoana R. Chorbadzhiyska, Peter A. Ivanov, Charlie Nation·Oct 24, 2025
The time-dependence of multi-point observable correlation functions are essential quantities in analysis and simulation of quantum dynamics. Open quantum systems approaches utilize two-point correlations to describe the influence of an environment on...
A truncated photon
Isak Cecil Onsager Rukan, Jan Gulla, Johannes Skaar·Oct 24, 2025
An elementary particle such as a photon cannot be cut in two pieces. Still it must be possible to truncate a photon with an optical shutter. The result is not another photon or a mix of a photon and a vacuum. Instead it is a superposition and mix of ...
RydIQule Version 2: Enhancing graph-based modeling of Rydberg atoms
Benjamin N. Miller, David H. Meyer, Carter A. Montag +4 more·Oct 24, 2025
Rydberg atomic radio-frequency (rf) sensors are an emerging technology platform that relies on vaporous atoms, interrogated with laser beams and nearly ionized, to receive rf signals. Rydberg rf sensors have a number of interesting fundamental distin...
Real-time decoding of the gross code memory with FPGAs
Thilo Maurer, Markus Bühler, Michael Kröner +4 more·Oct 24, 2025
We introduce a prototype FPGA decoder implementing the recently discovered Relay-BP algorithm and targeting memory experiments on the $[[144,12,12]]$ bivariate bicycle quantum low-density parity check code. The decoder is both fast and accurate, achi...
SHAP Meets Tensor Networks: Provably Tractable Explanations with Parallelism
Reda Marzouk, Shahaf Bassan, Guy Katz·Oct 24, 2025
Although Shapley additive explanations (SHAP) can be computed in polynomial time for simple models like decision trees, they unfortunately become NP-hard to compute for more expressive black-box models like neural networks - where generating explanat...
On the Schrödinger and Carroll Schrödinger Equations: Dualities and Applications
José Rojas, Enrique Casanova, Melvin Arias·Oct 24, 2025
We investigate precise structural relations between the standard Schrödinger equation and its Carrollian analogue-the Carroll-Schrödinger equation-in 1+1 dimensions, with emphasis on dualities, potential maps, and solution behavior. Our contributions...
Probing Sensitivity near a Quantum Exceptional Point using Waveguide Quantum Electrodynamics
Aziza Almanakly, Reouven Assouly, Harry Hanlim Kang +8 more·Oct 24, 2025
Non-Hermitian Hamiltonians with complex eigenenergies are useful tools for describing the dynamics of open quantum systems. In particular, parity and time (PT) symmetric Hamiltonians have generated interest due to the emergence of exceptional-point d...
Quantum Similarity-Driven QUBO Framework for Multi-Period Supply Chain Allocation using Time-Multiplexed Coherent Ising Machines and Simulated Quantum Annealing
Rushikesh Ubale, Yasar Mulani, Abhay Suresh +4 more·Oct 24, 2025
Multi-period stock-keeping unit (SKU) allocation in supply chains is a combinatorial optimization problem that is both NP-hard and operationally critical, requiring simultaneous attention to profitability, feasibility, and diversity. Quadratic uncons...
From Cables to Qubits: A Decomposed Variational Quantum Optimization Pipeline
Paul-Niklas Ken Kandora, Adrian Asmund Fessler, Robert Fabian Lindermann +3 more·Oct 24, 2025
The Cable Routing Optimization Problem (CROP) is a multi-flow routing task central to industrial layouts and smart manufacturing installations. We formulate CROP as a cable-wise separable, block-diagonal Quadratic Unconstrained Binary Optimization Pr...
Trajectories in coupled waveguides: an application to a recent experiment and Hiley's lessons on the falsification of the Bohmian model
F. Daem, T. Durt, A. Matzkin·Oct 24, 2025
From "surreal" trajectories to which-way measurements, Basil Hiley had a lesson: claims of falsifying the Bohmian model do not withstand scrutiny provided the model is applied correctly. In this work we compute de Broglie-Bohm trajectories for partic...
From Discrete to Continuous-Variable Systems via Jordan-Schwinger Tomographic Transformation
Liubov A. Markovich, Vladimir A. Orlov, Alexey N. Rubtsov +1 more·Oct 24, 2025
Hybrid quantum systems that combine discrete-variable (DV) and continuous-variable (CV) architectures represent a promising direction in quantum information science. However, transferring concepts, information and states between such fundamentally di...
3D micro-printing: An enabling technique for arbitrary potential landscapes for photonic quantum-gases
Julian Schulz, Kirankumar Karkihalli Umesh, Sven Enns +2 more·Oct 24, 2025
Photonic quantum gases explore the physics of open driven-dissipative quantum systems under ambient conditions and thus open access to thermodynamics and transport phenomena in quantum gases in the weakly interacting regime. Here we introduce the tec...
Exciton and biexciton preparation via coherent swing-up excitation in a GaAs quantum dot embedded in micropillar cavity
Claudia Piccinini, Aleksander Rodek, Abdulmalik A. Madigawa +9 more·Oct 24, 2025
Coherent control of quantum emitters is essential for scalable quantum photonic technologies. The recently proposed swing-up of quantum emitter (SUPER) scheme allows efficient and coherent preparation of single photons via off-resonant, red-detuned l...
Suppressing excitations using quantum-Brachistochrone and nearest-neighbour interactions
S John Sharon Sandeep, Dibyajyoti Sahu, Suhas Gangadharaiah·Oct 24, 2025
We examine excitation suppression in the transverse-field Ising model (TFIM), where finite-time drive across a quantum critical point is assisted by the presence of a time-dependent coupling parameter. While conventional counterdiabatic protocols are...
Heisenberg's S-matrix program and Feynman's divergence problem
Lev Sakhnovich·Oct 24, 2025
In the present article, we assume that the first approximation of the scattering operator is given and that it has the logarithmic divergence. This first approximation allows us to construct the so called deviation factor. Using the deviation factor,...
SCORENF: Score-based Normalizing Flows for Sampling Unnormalized distributions
Vikas Kanaujia, Vipul Arora·Oct 24, 2025
Unnormalized probability distributions are central to modeling complex physical systems across various scientific domains. Traditional sampling methods, such as Markov Chain Monte Carlo (MCMC), often suffer from slow convergence, critical slowing dow...
A complex Gaussian representation of continuum wavefunctions respectful of their asymptotic behaviour
Stéphanie Laure Egome Nana, Arnaud Leclerc, Lorenzo Ugo Ancarani·Oct 24, 2025
Complex Gaussian basis sets are optimized to accurately represent continuum radial wavefunctions over the whole space. First, attention is put on the technical ability of the optimization method to get more flexible series of Gaussian exponents, in o...
