Abstract: Quantum communications have progressed significantly, moving from a theoretical concept to small-scale experiments to recent metropolitan-scale demonstrations. As the technology matures, it is expected to revolutionize quantum computing in much the same way that classical networks revolutionized classical computing. Quantum communications will also enable breakthroughs in quantum sensing, metrology, and other areas. However, scalability […]

Abstract: This paper addresses the Bi-Objective Traveling Thief Problem (BI-TTP), a challenging multi-objective optimization problem that requires the simultaneous optimization of travel cost and item profit. Conventional methods for the BI-TTP often face severe scalability issues due to the complex interdependence between routing and packing decisions, as well as the inherent complexity and large problem […]

Accelerating the Max-Cut problems via distributed Ising machine solvers

February 23, 2026Xing-yu Wu, Yi-Xin Zhang, Chen-rui Fan, Chuan WangOpen AccessApproximation algorithms, Computational modeling, Distributed computing, Hardware, Optimization, Partitioning algorithms, Quantum computing, Qubit, Scalability, Stationary state

Abstract: The Ising machine, as a quantum-inspired computing system, can be used to efficiently solve combinatorial optimization problems. Ongoing studies have positioned it to potentially surpass the performance limitations of traditional computers. However, such Ising machines also suffer from scalability as the solution quality becomes sub-optimal when the problem size increases. In this work, we […]

Quantum secret sharing (QSS) is a cryptographic protocol that leverages quantum mechanics to distribute a secret among multiple parties. With respect to the classical counterpart, in QSS, the secret is encoded into quantum states and shared by a dealer such that only an authorized subsets of participants, i.e., the players, can reconstruct it. Several state-of-the-art […]

Benchmarking Quantum Circuit Transformation With QKNOB Circuits

January 8, 2025Sanjiang Li, Xiangzhen Zhou, Yuan FengQuantum SoftwareApproximation algorithms, Benchmark testing, Costs, Logic gates, Performance evaluation, Quantum circuit, Quantum mechanics, Qubit, Scalability, Transforms

Current superconducting quantum devices impose strict connectivity constraints on quantum circuit execution, necessitating circuit transformation before executing quantum circuits on physical hardware. Numerous quantum circuit transformation (QCT) algorithms have been proposed. To enable faithful evaluation of state-of-the-art QCT algorithms, this article introduces qubit mapping benchmark with known near-optimality (QKNOB), a novel benchmark construction method for […]
