Kibble-Zurek Mechanism in the Open Quantum Rabi Model
T. Pirozzi, G. Di Bello, V. Cataudella +2 more·Mar 17, 2026
The Kibble-Zurek mechanism provides a universal framework for predicting defect formation in non-equilibrium phase transitions. While Markovian dissipation typically degrades universal scaling, the impact of non-Markovian memory remains largely unexp...
FAlCon: A unified framework for algorithmic control of quantum dot devices
Tyler J. Kovach, Daniel Schug, Zach D. Merino +3 more·Mar 17, 2026
As spin-based quantum systems scale, their setup and control complexity increase sharply. In semiconductor quantum dot (QD) experiments, device-to-device variability, heterogeneous control-electronics stacks, and differing operational modalities make...
Dark state role in time-reversal symmetry breaking
Dario Fasone, Rita Veilande, Luigi Giannelli +5 more·Mar 17, 2026
We investigate the role of the global driving phase $Φ$ in the dynamics of driven few-level quantum systems, a central setting in coherent control of atomic, molecular, and solid-state platforms. In particular, we focus on systems with closed-loop co...
Monte Carlo sampling from a projected entangled-pair state in simulations of quantum annealing in the three dimensional random Ising model
Jacek Dziarmaga·Mar 17, 2026
Quantum annealing with the D-Wave Advantage system in the random Ising model on a cubic lattice is simulated using a three-dimensional (3D) tensor network. The Hamiltonian is driven across a quantum phase transition from a paramagnetic phase to a spi...
How Quantum Circuits Actually Learn: A Causal Identification of Genuine Quantum Contributions
Cyrille Yetuyetu Kesiku, Begonya Garcia-Zapirain·Mar 17, 2026
Attributing performance gains in quantum machine learning to genuine quantum resources rather than to classical architectural scaling remains an open methodological challenge. We address this by introducing a counterfactual causal mediation framework...
Two-Dimensional Far-Field Correlations of X-ray Photon Pairs
E. Strizhevsky, Y. Klein, R. Hartmann +9 more·Mar 17, 2026
We directly observe far-field correlations of x-ray photon pairs generated by spontaneous parametric down-conversion (SPDC). Using an energy-resolved, two-dimensional photon counting detector we record the full ring-shaped emission of both photons ac...
Generative AI for Quantum Circuits and Quantum Code: A Technical Review and Taxonomy
Juhani Merilehto·Mar 17, 2026
We review thirteen generative systems and five supporting datasets for quantum circuit and quantum code generation, identified through a structured scoping review of Hugging Face, arXiv, and provenance tracing (January-February 2026). We organize the...
A Scalable Open-Source QEC System with Sub-Microsecond Decoding-Feedback Latency
Junyi Liu, Yi Lee, Yilun Xu +2 more·Mar 17, 2026
Quantum error correction (QEC) is essential for realizing large-scale, fault-tolerant quantum computation, yet its practical implementation remains a major engineering challenge. In particular, QEC demands precise real-time control of a large number ...
CPDNN quantum channels with qubit output are CPCP
Hyunho Cha·Mar 17, 2026
The resource theory for nonnegativity of quantum amplitudes distinguishes completely positive completely positive (CPCP) quantum channels from the larger and more tractable class of completely positive doubly nonnegative (CPDNN) quantum channels. It ...
N-Cavity-Magnon Polariton Blockade via Kerr Nonlinearity
Zhe-Qi Yang, Xiao-Yu Bi, Zhi-Rong Zhong·Mar 17, 2026
We theoretically propose a scheme to realize a $n$-cavity-magnon polariton blockade in a cavity-magnon system by utilizing the Kerr nonlinearity. Cavity-magnon polaritons are hybrid quasiparticles formed by the strong coupling between cavity photons ...

We have investigated the geometric phase acquired by a uniformly accelerated two-level atom coupled to vacuum fluctuations of a massless conformal scalar field in Anti-de Sitter (AdS) spacetime. Using the open-quantum-system formalism, we calculate t...
Dissipative realization of a quantum distance-based classifier using open quantum walks
Pedro Linck Maciel, Graeme Pleasance, Francesco Petruccione +1 more·Mar 16, 2026
Open quantum walks (OQWs) constitute a class of quantum walks whose dynamics are entirely driven by interactions with the environment. It is well known that OQWs provide a general framework for implementing dissipative quantum computation. In this wo...
Statistics-governed dynamical scaling in interacting anyonic chains
Xu-Chen Yang, Botao Wang, Jianpeng Liu +3 more·Mar 16, 2026
Particle statistics impose fundamental constraints on nonequilibrium quantum dynamics, yet it remains an open question whether anyonic statistics can lead to emergent dynamical scaling beyond the conventional Bose-Fermi paradigm. Here we investigate ...
