Identifying vulnerable nodes and detecting malicious entanglement patterns to handle st-connectivity attacks in quantum networks
Iain Burge, Michel Barbeau, Joaquin Garcia-Alfaro·Feb 1, 2025
Problems in distributed system security often map naturally to graphs. The concept of centrality assesses the importance of nodes in a graph. It is used in various applications. Cooperative game theory has also been used to create nuanced and flexibl...
On Multiquantum Bits, Segre Embeddings and Coxeter Chambers
N. Combe·Feb 1, 2025
This work explores the interplay between quantum information theory, algebraic geometry, and number theory, with a particular focus on multiqubit systems, their entanglement structure, and their classification via geometric embeddings. The Segre embe...
Left-Deep Join Order Selection with Higher-Order Unconstrained Binary Optimization on Quantum Computers
Valter Uotila·Feb 1, 2025
Join order optimization is among the most crucial query optimization problems, and its central position is also evident in the new research field where quantum computing is applied to database optimization and data management. In this field, join ord...
Stress accommodation in nanoscale dolan bridges designed for superconducting qubits
Sueli Skinner-Ramos, Matthew L. Freeman, Douglas Pete +3 more·Feb 1, 2025
Josephson junctions are the principal circuit element in numerous superconducting quantum information devices and can be readily integrated into large-scale electronics. However, device integration at the wafer scale necessarily depends on having a r...
Thermodynamic limits of the Mpemba effect: A unified resource theory analysis of correlation-enabled mechanisms
Doruk Can Alyürük, Mahir H. Yeşiller, Vlatko Vedral +1 more·Jan 31, 2025
The Mpemba effect, in which a hotter system cools faster than a colder one, remains one of the most intriguing anomalies in thermodynamics. Here, we investigate its microscopic origin within the framework of quantum resource theories and introduce co...
VeloxQ: A Fast and Efficient QUBO Solver
J. Pawłowski, J. Tuziemski, P. Tarasiuk +5 more·Jan 31, 2025
We introduce VeloxQ, a fast solver for Quadratic Unconstrained Binary Optimization (QUBO) problems, which are central to many real-world optimization tasks. Unlike approaches that depend on emerging quantum hardware, VeloxQ can be deployed on convent...
Estimating the Power of a Quantum Computer
Brandon Rodenburg·Jan 31, 2025
Various benchmarking metrics have been developed to quantify the performance of quantum computing hardware and help evaluate development. However, it is not always necessary to know the metric values precisely. This is especially true for potential e...
From Bits to Qubits: Challenges in Classical-Quantum Integration
S. Kulkarni, Daniel Huang, E. .. Bethel·Jan 31, 2025
While quantum computing holds immense potential for tackling previously intractable problems, its current practicality remains limited. A critical aspect of realizing quantum utility is the ability to efficiently interface with data from the classica...
Randomized benchmarking with leakage errors
Yi-Hsiang Chen, Charles H. Baldwin·Jan 31, 2025
Leakage errors are unwanted transfer of population outside of a defined computational subspace and they occur in almost every platform for quantum computing. While prevalent, leakage is often overlooked when measuring and reporting the fidelity of qu...
