I am a PhD student in Information Technology at Politecnico di Milano.
My research is in quantum computing, with a focus on quantum error correction (QEC) and quantum compiler architectures:
Abstract: We propose Best-First Ordered Statistics Decoding (BF-OSD), an algorithmic enhancement to the belief propagation plus ordered statistics decoding pipeline for quantum low-density parity-check (QLDPC) codes. By prioritizing error candidates through a best-first heuristic tree search over syndrome-compatible sub-spaces, BF-OSD achieves decoding performance on par with higher-order OSD while drastically cutting candidate exploration complexity and latency.

Abstract: Transpilation of quantum circuits to hardware-native topologies and gate libraries is a critical bottleneck in NISQ and early fault-tolerant quantum devices. In this work, we introduce an autoregressive transformer architecture that learns optimal gate substitution and routing strategies, mapping OpenQASM representations to target architectures (such as IonQ trapped-ion systems) with high fidelity and reduced gate counts.
