Microscopic model for a spatial multimode generation based on Multi-pump Four Wave Mixing in hot vapours
H. M. Florez·Dec 17, 2025
Multipartite entanglement is an important resource for quantum information processing. It has been shown that it is possible to employ alkali atoms to implement single device multipartite entanglement by using nonlinear processes with spatial modes. ...
Graph-theoretical search for integrable multistate Landau-Zener models
Zixuan Li, Chen Sun·Dec 17, 2025
The search for exactly solvable models is an evergreen topic in theoretical physics. In the context of multistate Landau-Zener models -- $N$-state quantum systems with linearly time-dependent Hamiltonians -- the theory of integrability provides a fra...
Characterizing entanglement shareability and distribution in $N$-partite systems
Hui Li, Ting Gao, Fengli Yan·Dec 17, 2025
Exploring the shareability and distribution of entanglement possesses fundamental significance in quantum information tasks. In this paper, we demonstrate that the square of bipartite entanglement measures $G_q$-concurrence, which is the generalizati...
Enabling Technologies for Scalable Superconducting Quantum Computing
Xanthe Croot, Kasra Nowrouzi, Christopher Spitzer +21 more·Dec 17, 2025
Experiments with superconducting quantum processors have successfully demonstrated the basic functions needed for quantum computation and evidence of utility, albeit without a sizable array of error-corrected qubits. The realization of the full poten...
Trade-off relations and enhancement protocol of quantum battery capacities in multipartite systems
Yiding Wang, Xiaofen Huang, Shao-Ming Fei +1 more·Dec 17, 2025
First, we investigate the trade-off relations of quantum battery capacities in two-qubit system. We find that the sum of subsystem battery capacity is governed by the total system capacity, with this trade-off relation persisting for a class of Hamil...
High efficiency controlled quantum secure direct communication with 4D qudits and Grover search algorithm
Ni-Shi Lu, Ping Zhou·Dec 17, 2025
Currently, the progress of quantum secure direct communication (QSDC) is impeded by a fundamental trade off among control efficiency, security, and scalability. This study proposes an innovative controlled QSDC protocol based on a collaborative unita...
Quantum Machine Learning for Cybersecurity: A Taxonomy and Future Directions
Siva Sai, Ishika Goyal, Shubham Sharma +3 more·Dec 17, 2025
The increasing number of cyber threats and rapidly evolving tactics, as well as the high volume of data in recent years, have caused classical machine learning, rules, and signature-based defence strategies to fail, rendering them unable to keep up. ...
Roadmap: 2D Materials for Quantum Technologies
Qimin Yan, Tongcang Li, Xingyu Gao +29 more·Dec 16, 2025
Two-dimensional (2D) materials have emerged as a versatile and powerful platform for quantum technologies, offering atomic-scale control, strong quantum confinement, and seamless integration into heterogeneous device architectures. Their reduced dime...
Pulsed single-photon spectroscopy of an emitter with vibrational coupling
Sourav Das, Aiman Khan, Elnaz Darsheshdar +2 more·Dec 16, 2025
We analytically derive the quantum state of a single-photon pulse scattered from a single quantum two-level emitter interacting with a vibrational bath. This solution for the quadripartite system enables an information-theoretic characterization of v...
Quantum Radiometric Calibration
Leif Albers, Jan-Malte Michaelsen, Roman Schnabel·Dec 16, 2025
Optical quantum computing, as well as quantum communication and sensing technology based on quantum correlations are in preparation. These require photodiodes for the detection of about 10^16 photons per second with close to perfect quantum efficienc...
Sample-based quantum diagonalization as parallel fragment solver for the localized active space self-consistent field method
Qiaohong Wang, Mario Motta, Ruhee D'Cunha +7 more·Dec 16, 2025
Accurately and efficiently describing strongly correlated electronic systems is a central challenge in quantum computational chemistry, with classical and quantum computers. The localized active space self-consistent field method (LASSCF) uses a prod...
Women in Theoretical Quantum Physics in Brazil:demographics, career profiles, recognition, and leadership
Tatiana Pauletti, Paula Homem de Mello, Thereza Paiva +1 more·Dec 16, 2025
Gender imbalance in Physics remains a persistent global challenge, and Brazil is no exception. While women account for only 24% of Physics faculty in the country, their representation in Quantum Physics is even smaller. In this work, we provide the f...
Quantum Fisher-information limits of resonant nanophotonic sensors: why high-Q is not optimal even at the quantum limit
J. Sumaya-Martinez·Dec 16, 2025
We develop a quantum metrological framework for resonant nanophotonic sensors based on subwavelength Fabry--Perot slit cavities. Building on classical Fisher-information analyses of resonant transmission sensors, we model parameter encoding as a phas...
Geometric Latent Space Tomography with Metric-Preserving Autoencoders
S. M. Yousuf Iqbal Tomal, Abdullah Al Shafin·Dec 16, 2025
Quantum state tomography faces exponential scaling with system size, while recent neural network approaches achieve polynomial scaling at the cost of losing the geometric structure of quantum state space. We introduce geometric latent space tomograph...
Hyperfine spectroscopy of optical-cycling transitions in singly ionized thulium
Patrick Müller, Andrei Tretiakov, Amanda Younes +3 more·Dec 16, 2025
We present a spectroscopic investigation of $^{169}\mathrm{Tm}^+$ that provides two key foundations for its use as a platform for advanced quantum applications. First, we establish the complete spectroscopic road map for optical cycling (including la...
Exact formula for geometric quantum complexity of cosmological perturbations
Satyaki Chowdhury, Jakub Mielczarek·Dec 16, 2025
Nielsen's geometric approach offers a powerful framework for quantifying the complexity of unitary transformations. In this formulation, complexity is defined as the length of the minimal geodesic in a suitably constructed geometric space associated ...
Large-$n$ $O(n)$ with long-range interactions: integrability and resonance dynamics
Guido Giachetti, Nicolo Defenu·Dec 16, 2025
We study the the large-$n$ dynamics of the long-range quantum $O(n)$ model, focusing on the strong long-range regime $α<d$. The dynamics of the model exhibits non-trivial features on mesoscopic timescales $t\sim\ln N$, due to the activation of parame...

Gard Olav Helle, Tommaso Benacchio, Anna Bomme Ousager +1 more·Dec 16, 2025
We present a quantum algorithm for the simulation of the linear advection-diffusion equation based on block encodings of high order finite-difference operators and the quantum singular value transform. Our complexity analysis shows that the higher or...
Noise-Induced Thermalization in Quantum Systems
Sameer Dambal, Yu Zhang, Eric R Bittner +1 more·Dec 16, 2025
In the current Noisy Intermediate-Scale Quantum era, noise is widely regarded as the primary obstacle to achieving fault-tolerant quantum computation. However, certain stages of the quantum computing pipeline can, in fact, benefit from this noise. In...
Entanglement without Quantum Mechanics: Operational Constraints on the Quantum Signature
Samuel Schlegel, Borivoje Dakić, Flavio Del Santo·Dec 16, 2025
Entanglement is often regarded as an inherently quantum feature. We show that this does not have to be the case: under restricted operational access, classical correlations can appear nonseparable when expressed in the formalism of quantum mechanics....
