Sommario
On Friday, February 13th, 2026, we will have a new talk for the series #NECSTFridayTalk.During this talk, we will have, as speaker, Marco Venere, PhD at Dipartimento di Elettronica, Informazione e Bioingegneria.
Quantum computing is a new paradigm of computation that exploits principles from quantum mechanics to achieve an exponential speedup compared to classical logic. However, noise strongly limits current quantum hardware, reducing achievable performance and limiting the scaling of the applications. For this reason, current noisy intermediate-scale quantum devices require Quantum Error Correction (QEC) mechanisms to identify errors occurring in the computation and correct them in real-time. Nevertheless, the high computational complexity of QEC algorithms is incompatible with the tight time constraints of quantum devices. Thus, hardware acceleration is paramount to achieving real-time QEC. This work presents QASBA, an FPGA-based hardware accelerator for the Sparse Blossom Algorithm (SBA), a state-of-the-art decoding algorithm. After profiling the state-of-the-art software counterpart, we developed a design methodology for hardware development based on the SBA. We also devised an automation process to help users without expertise in hardware design in deploying architectures based on QASBA. We implemented QASBA on different FPGA architectures and experimentally evaluated resource usage, execution time, and energy efficiency of our solution. Our solution attains up to 25.05× speedup and 304.16× improvement in energy efficiency compared to the software baseline.
The NECSTLab is a DEIB laboratory, with different research lines on advanced topics in computing systems: from architectural characteristics, to hardware-software codesign methodologies, to security and dependability issues of complex system architectures.
