Efficient Time-Aware Partitioning of Quantum Circuits for Distributed Quantum Computing
Raymond P. H. Wu, Chathu Ranaweera, Sutharshan Rajasegarar +3 more·Mar 4, 2026
To overcome the physical limitations of scaling monolithic quantum computers, distributed quantum computing (DQC) interconnects multiple smaller-scale quantum processing units (QPUs) to form a quantum network. However, this approach introduces a crit...
Entanglement between quantum dots transmitted via Majorana wire: Insights from the fermionic negativity, concurrence and quantum mutual information
C. Jasiukiewicz, A. Sinner, I. Weymann +2 more·Mar 4, 2026
We study quantum entanglement in a system comprising two quantum dots interconnected through the short topological superconducting nanowire, which hosts overlapping boundary Majorana modes. Inspecting the fermionic negativity, we analyze the variatio...

Jean-Daniel Fekete, Yifan Hu, Dominik Moritz +8 more·Mar 4, 2026
The rapid advancement of AI is transforming human-centered systems, with profound implications for human-AI interaction, human-data interaction, and visual analytics. In the AI era, data analysis increasingly involves large-scale, heterogeneous, and ...
Spectral Bath Engineering for Quantum-Enhanced Agrivoltaics: Advancing Efficiency and Environmental Sustainability via Non-Markovian Dynamics
Steve Cabrel Teguia Kouam, Theodore Goumai Vedekoi, Jean-Pierre Tchapet Njafa +2 more·Mar 4, 2026
As global demand for food and clean energy intensifies, agrivoltaic systems have emerged as a vital solution for land-use optimization. However, current designs overwhelmingly treat incident light as a classical photon flux, overlooking the quantum m...
The Steiner Tree Problem: Novel QUBO Formulation and Quantum Annealing Implementation
Dan Li, Xiang-Hui Wu, Ji-Rong Liu·Mar 4, 2026
The Steiner Tree Problem (STP) is a well-known NP-hard combinatorial optimization problem, which has wide applications in network design, integrated circuit layout, bioinformatics, and other fields. However, traditional algorithms often struggle to b...
Air-stable bright entangled photon-pair source from graphene-encapsulated van der Waals ferroelectric NbOI2
Mayank Joshi, Mengting Jiang, Yu Xing +6 more·Mar 4, 2026
Van der Waals (vdW) ferroelectrics are emerging nonlinear photonic materials that combine large second-order susceptibility \c{hi}(2) with heterostructure compatibility, offering an attractive route toward miniaturized spontaneous parametric down-con...
(Quantum) reference frames, relational observables, gauge reduction and physical interpretation
Thomas Thiemann·Mar 4, 2026
It is mandatory to know how to operationally define and translate a reference frame into mathematics, in order that a physical interpretation of theory calculations in terms of observational data is possible. The situation is particularly challenging...
Deterministic Quantum Jump (DQJ) Method for Weakly Dissipative Systems
Marcus Meschede, Ludwig Mathey·Mar 4, 2026
Physical quantum systems are generically coupled to an environment, resulting in open system dynamics. A typical approach to simulating this dynamics is to propagate the density matrix of the system via the Lindblad master equation. This approach is ...
Fermi-Dirac thermal measurements: A framework for quantum hypothesis testing and semidefinite optimization
Nana Liu, Mark M. Wilde·Mar 4, 2026
Quantum measurements are the means by which we recover messages encoded into quantum states. They are at the forefront of quantum hypothesis testing, wherein the goal is to perform an optimal measurement for arriving at a correct conclusion. Mathemat...
Spectrally Corrected Polynomial Approximation for Quantum Singular Value Transformation
Krishnan Suresh·Mar 4, 2026
Quantum Singular Value Transformation (QSVT) provides a unified framework for applying polynomial functions to the singular values of a block-encoded matrix. QSVT prepares a state proportional to $\bA^{-1}\bb$ with circuit depth $O(d\cdot\mathrm{poly...
Lord Kelvin's Second Cloud
Gilles Montambaux·Mar 4, 2026
On April 27, 1900, William Thomson, better known as Lord Kelvin, delivered a visionary speech before the Royal Institution of Great Britain. In it, he presented two unresolved problems which, to him, appeared fundamental and unavoidable at the turn o...
Variance-Driven Mean Temperature Reduction in Nonuniformly Heated Radiative-Conductive Systems
Juntao Lu, Zihan Zhang, Yongjian Xiong +1 more·Mar 4, 2026
Radiative-conductive systems are intrinsically nonlinear due to the quartic temperature dependence of thermal radiation. Under fixed total heating power, convexity arguments imply that nonuniform temperature distributions radiate more efficiently and...
Imaginary-time evolution of interacting spin systems in the truncated Wigner approximation
Tom Schlegel, Dennis Breu, Michael Fleischhauer·Mar 4, 2026
We present a semiclassical phase-space method to calculate thermal and ground states of large interacting spin systems. To this end, we extend the recently developed truncated Wigner approximation for spins (TWA) to the imaginary time, termed iTWA. T...
Resource State Distillation via Stabilizer Channels
Christopher Popp, Tobias C. Sutter, Beatrix C. Hiesmayr·Mar 4, 2026
Quantum technologies rely on high-quality resource states, such as maximally entangled or private states, which are indispensable for quantum communication and cryptography. In practice, however, these states are inevitably degraded by noise. Distill...
Collective purification of interacting quantum networks beyond symmetry constraints
Saikat Sur, Pritam Chattopadhyay, Arnab Chakrabarti +5 more·Mar 4, 2026
Following any quantum information processing protocol, it is essential to reset a mixed state of a many-body interacting spin-network to the computational-zero pure state. This task is challenging, both theoretically and experimentally, because of th...
