Italy's Competition Authority has initiated an antitrust investigation into the quantum computing sector, citing concerns over potential competition risks as the technology approaches commercialization. The probe focuses on structural issues, including high entry barriers, customer lock-in risks, and the potential for early technological dominance driven by rapid patent accumulation. Regulators aim to assess market dynamics early, drawing parallels with the artificial intelligence sector and acknowledging the strategic importance of quantum computing for national and European interests. The investigation highlights the need for vigilance in ensuring a level playing field in the quantum computing sector, particularly as companies like Intel drive progress in quantum developments, narrowing the timeline for cryptographic migration1. This matters to practitioners because the urgency to plan for post-quantum cryptography increases as quantum computing advances, underscoring the need for proactive measures to mitigate potential risks.
