Quantification of the energy consumption of entanglement distribution
K. Horodecki, Marek Winczewski, Leonard Sikorski +3 more·Jul 30, 2025
Inspired by environmental sciences, we develop a framework to quantify the energy needed to generate quantum entanglement via noisy quantum channels, focusing on the hardware-independent, i.e. fundamental cost. Within this framework, we define a meas...
Enhanced Prediction of CAR T-Cell Cytotoxicity with Quantum-Kernel Methods
F. Utro, Meltem Tolunay, Kahn Rhrissorrakrai +6 more·Jul 30, 2025
Chimeric antigen receptor (CAR) T-cells are T-cells engineered to recognize and kill specific tumor cells. Through their extracellular domains, CAR T-cells bind tumor cell antigens which triggers CAR T activation and proliferation. These processes ar...

Samir Belaloui, N. Belaloui, Achour Benslama·Jul 30, 2025
We investigate the electronic structure of methanimine (CH2NH) and water (H2O) molecules in an effort to locate conical intersections (CIs) using variational quantum algorithms. Our approach implements and compares a range of hybrid quantum-classical...
Hybrid Quantum Classical Surrogate for Real Time Inverse Finite Element Modeling in Digital Twins
A. Alavi, Sanduni Jayasinghe, M. Mahmoodian +3 more·Jul 30, 2025
Large-scale civil structures, such as bridges, pipelines, and offshore platforms, are vital to modern infrastructure, where unexpected failures can cause significant economic and safety repercussions. Although finite element (FE) modeling is widely u...
Measurement-induced cubic phase state generation
Harsh Kashyap, Denis A. Kopylov, Polina R. Sharapova·Jul 29, 2025
The cubic phase state constitutes a nonlinear resource that is essential for universal quantum computing protocols. However, constructing such non-classical states faces many challenges. In this work, we present a protocol for generating a cubic phas...
Complexity in multi-qubit and many-body systems
Imre Varga·Jul 29, 2025
Characterizing complexity and criticality in quantum systems requires diagnostics that are both computationally tractable and physically insightful. We apply a measure of quantum state complexity for n-qubit systems, defined as the divergence between...
Analysis of Quantum Image Representations for Supervised Classification
Marco Parigi, Mehran Khosrojerdi, Filippo Caruso +1 more·Jul 29, 2025
In the era of big data and artificial intelligence, the increasing volume of data and the demand to solve more and more complex computational challenges are two driving forces for improving the efficiency of data storage, processing and analysis. Qua...
Sampling (noisy) quantum circuits through randomized rounding
Victor Martinez, Omar Fawzi, Daniel Stilck França·Jul 29, 2025
The present era of quantum processors with hundreds to thousands of noisy qubits has sparked interest in understanding the computational power of these devices and how to leverage it to solve practically relevant problems. For applications that requi...
Prime Factorization Equation from a Tensor Network Perspective
Alejandro Mata Ali, Jorge Martínez Martín, Sergio Muñiz Subiñas +3 more·Jul 29, 2025
This paper presents an exact and explicit tensor-network equation for the search of nontrivial divisors of a composite integer, together with an algorithm for its computation. The proposed method is based on the MeLoCoToN approach, which addresses co...
Complete Positivity of Subsystems in Quantum Dynamics
Anumita Mukhopadhyay, Praggnyamita Ghosh, Shibdas Roy·Jul 29, 2025
Although many quantum channels satisfy Completely Positive Trace Preserving (CPTP) condition, there are valid quantum channels that can be non-completely positive (NCP). As memory effects can provide advantages in the dynamics of noisy quantum system...
