André Xuereb
Founder and CEO
André Xuereb is a full professor of quantum physics at the University of Malta, where he established the quantum research group, and Founder & CEO of Merqury Cybersecurity. He read for an undergraduate degree in mathematics and physics at the University of Malta, a PhD in theoretical physics at the University of Southampton in the UK, and a master’s degree in entrepreneurship at the University of Malta; he is currently reading for a master’s degree in diplomacy. Since 2021, André is Malta’s Ambassador for Digital Affairs. In addition to this, he is also Chief Scientific Officer of an artificial intelligence start-up, married to a lawyer, and the proud father of three wonderful children
Merqury works with the quantum technologies research group at the University of Malta. It builds on expertise grown over the course of the preceding decade, including through participation in large-scale research initiatives funded by the European Commission, NATO, and local funding mechanisms.
Milestones achieved by this research group include the establishment of a quantum link between Malta and Sicily over the telecommunications network, subsequently extended to a round-trip from Malta to Sicily and back. We truly are at the forefront of the quantum revolution.

For those suffering from Quantum breakthrough fatigue, it is not going to let up as this so eloquently explains. I foresee, within 3-4 years, PQ Readiness will emerge as a commercial strategic advantage for organisations with it sitting shoulder to shoulder with QAI, and QCloud, and Q-this and Q-that!
