Ireland is emerging as a key player in the development of quantum computing, leveraging its rich history in mathematics and physics, as well as its modern-day concentration of tech firms and universities. The country's connection to the field dates back to the 19th century with Dublin-born physicist William Rowan Hamilton, who laid the mathematical groundwork for quantum mechanics. Today, Ireland is home to a number of multinational technology companies and universities that are actively teaching and researching quantum computing. This positioning is significant, as quantum developments, particularly in areas like DeFi, are accelerating the need for cryptographic migration to post-quantum cryptography (PQC)1. As a result, the urgency for PQC planning is increasing, making Ireland's role in shaping the future of quantum computing all the more important. This matters to practitioners because it highlights the need for proactive planning and investment in quantum-resistant technologies to stay ahead of the curve.
