Special Issue Information

Dear Colleagues,

We invite researchers and experts to contribute their original work to a Special Issue on "Recent Advances in Quantum Hybrid Systems". The synergy between diverse forms of quantum and classical processing is vital to the rapid advancement of quantum computing. This Special Issue aims to showcase the latest progress in different aspects of hybrid quantum classical systems, ranging from applications to devices. Topics of interest include novel applications for quantum acceleration, software for quantum systems, hybrid quantum algorithms, quantum-inspired approaches, fault-tolerant quantum computing, quantum peripheral electronics, and quantum/classical resource estimation.

We welcome high-quality submissions that explore these topics and related areas, focusing on cutting-edge research, new tools and methods, and practical utility. Contributions may include original research papers, review articles, or perspectives; we are looking to provide a comprehensive overview of the field.

By participating in this Special Issue, you will have the opportunity to contribute to our collective knowledge of quantum hybrid systems and shape the future of this exciting field. All submissions will undergo a rigorous peer-review process conducted by field experts. We look forward to receiving your valuable contributions.

This paper presents a system for solving binary-valued linear equations using quantum computers. The system is called Mod2VQLS, which stands for Modulo 2 Variational Quantum Linear Solver. As far as we know, this is the first such proposal. The design is a classical–quantum hybrid. The quantum components are a new circuit design for implementing matrix multiplication modulo 2, and a variational circuit to be optimized. The classical components are the optimizer, which measures the cost function and updates the quantum parameters for each iteration, and the controller that runs the quantum job and classical optimizer iterations. We propose two alternative ansatze or templates for the variational circuit and present results showing that the rotation ansatz designed specifically for this problem provides the most direct path to a valid solution. Numerical experiments in low dimensions indicate that Mod2VQLS, using the custom rotations ansatz, is on par with the block Wiedemann algorithm, which is the best-known to date solution for this problem.
