This episode of the Physics World Weekly podcast features Ignacio Cirac, who has won the 2026 Isaac Newton Medal and Lecture for his “pioneering contributions that founded modern quantum information science, uniting profound theoretical insight, experimental vision, and exceptional scientific leadership shaping quantum physics and technology worldwide”.
Cirac is director of the theory division at the Max-Planck-Institute for Quantum Optics in Germany.
In conversation with Physics World’s Michael Banks, Cirac explains how an early interest in mathematics and science fiction drew him to quantum information – along with the field’s potential to create new technologies.
He talks about his collaboration in the 1990s with Peter Zoller to design quantum simulators and computers based on trapped-ion qubits. Cirac weighs up the pros and cons of the qubit technologies available today and highlights the benefits of systems based on Rydberg atoms.
Looking to the future, Cirac cautions against quantum hype and points out that it is still not clear how quantum technologies will be used in the future. He also calls on European academics to maintain their scientific excellence and for more money to be invested in the continent’s quantum industries.
This podcast is supported by American Elements, the world’s leading manufacturer of engineered and advanced materials. The company’s ability to scale laboratory breakthroughs to industrial production has contributed to many of the most significant technological advancements since 1990 – including LED lighting, smartphones, and electric vehicles.
