Finite de Finetti for convex bodies and Polynomial Optimization

Julius A. Zeiss, Gereon Koßmann, René Schwonnek +1 more·Jan 21, 2026

Leveraging a recently proposed notion of relative entropy in general probabilistic theories (GPT), we prove a finite de Finetti representation theorem for general convex bodies. We apply this result to address a fundamental question in polynomial opt...

Trimer Dynamics in Floquet-driven arrays of Rydberg Atoms

Edoardo Tiburzi, Lorenzo Maffi, Luca Dell'Anna +1 more·Jan 21, 2026

We analyze the WAHUHA Floquet protocol recently applied to arrays of Rydberg atoms and derive beyond-leading-order corrections in the high-frequency expansion of the effective spin theory. We find that an appropriate choice of the pulses times can en...

Entanglement summoning from entanglement sharing

Lana Bozanic, Alex May, Stanley Miao·Jan 21, 2026

In an entanglement summoning task, a set of distributed, co-operating parties attempt to fulfill requests to prepare entanglement between distant locations. The parties share limited communication resources: timing constraints may require the entangl...

Bose condensation and Bogoliubov excitation in resonator-embedded superconducting qubit network

Patrick Navez, Valentina Di Meo, Berardo Ruggiero +12 more·Jan 21, 2026

Superconducting qubit networks (SQNs) embedded in a low-dissipative resonator is a promising device allowing one not only to establish the collective quantum dynamics on a macroscopic scale but also to greatly enhance the sensitivity of detectors of ...

Stimulated cooling in non-equilibrium Bose-Einstein condensate

Ka Kit Kelvin Ho, Vladislav Yu. Shishkov, Mohammad Amini +10 more·Jan 21, 2026

We report on the experimental observation of stimulated cooling in the non-equilibrium Bose-Einstein condensate (BEC) of weakly interacting exciton-polaritons from approximately room temperature down to 20K. By resolving the condensate in energy-mome...

Two-Qubit Spin-Boson Model in the Strong Coupling Regime: Coherence, Non-Markovianity, and Quantum Thermodynamics

Hasan Mehdi Rizvi, Devvrat Tiwari, Subhashish Banerjee·Jan 21, 2026

We investigate the dynamics of a two-qubit open quantum system, in particular the two-qubit spin-boson model in the strong coupling regime, coupled to two thermal bosonic baths under non-Markovian and non-equilibrium conditions. Two complementary app...

Cavity-QED tools for MBQC with optical binomial-codes

G. P. Teja, Radim Filip·Jan 21, 2026

Measurement-based quantum computation (MBQC) offers a promising paradigm for photonic quantum computing, but its implementation requires the generation of specific non-Gaussian resource states. While continuous-variable encodings such as the highly c...

A framework to evaluate the performance of Variational Quantum Algorithms

Ernesto Mamedaliev, Vladyslav Libov, Albert Nieto-Morales +2 more·Jan 21, 2026

Variational Quantum Algorithms (VQAs) are promising methods for solving combinatorial optimization problems on noisy intermediate-scale quantum (NISQ) devices. However, benchmarking VQAs is difficult due to their stochastic behavior and the lack of s...

Multipartite entanglement in the quantum tetrahedron

Robert Amelung, Hanno Sahlmann·Jan 21, 2026

The space $\mathrm{Inv}(j_1,j_2,j_3,j_4)$ of SU(2)-invariant four-valent tensors, also known as intertwiners, can be understood as the quantum states of a tetrahedron in Euclidean space with fixed areas. In loop quantum gravity, they are states of th...

Impossible Counterfactuals, Discrete Hilbert Space and Bell's Theorem

Tim Palmer·Jan 21, 2026

Negating the Measurement Independence assumption (MI) is often referred to as the `third way' to account for the experimental violation of Bell's inequality. However, this route is generally viewed as ludicrously contrived, implying some implausible ...
