Ignacio Cirac wins 2026 Isaac Newton Medal for pioneering contributions that founded modern quantum information science
The Institute of Physics has given Ignacio Cirac its 2026 Isaac Newton Medal and Prize. Physics World, the IOP's own magazine, links it to his 1990s trapped-ion proposal with Peter Zoller.

What happened
- The IOP's citation credits Cirac with "pioneering contributions that founded modern quantum information science".
- Cirac also showed that controlled quantum many-body systems can act as simulators for hard problems in physics, chemistry and materials science.
- With collaborators he pioneered long-distance quantum communication, including the quantum repeater idea for distributing entanglement despite losses and imperfections.
- His earlier honours include the Wolf Prize in Physics in 2013 and the Max Planck Medal in 2018.
Why it matters
- constraint The hardware credit attaches to trapped ions, which the report calls one of the leading platforms.
- decision A team weighing quantum platforms cannot use this award as a comparison. A prize citation records esteem for a body of work and is not a benchmark on scale, error rate or cost.
- constraint The significance claims come from the IOP's own publication, quoting the IOP's president. They are the awarder's own assessment.
Everything here arrives through one outlet. Physics World is published by the IOP, the body that gives the medal [3], and the citation, the praise from IOP president Paul Howarth and Cirac's reply all appear in its report [2][8][11].
The scientific claim is narrower than the medal's wording. According to Physics World, the Cirac-Zoller proposal gave "an experimentally plausible route" from the theoretical idea of a quantum computer to an actual machine [5]. The evidence the report offers that the route held up is that trapped ions remain "one of the leading quantum-computing platforms today" [5].
"One of" is the report's own limit. It makes trapped ions a contender among platforms, so the credit for working hardware attaches to that platform.
The report does not say how trapped-ion machines compare with other designs in practice, or which measure "leading" refers to. It could be qubit count, error rate or cost.
Howarth gave the broader frame. "Professor Cirac's pioneering work has helped shape modern quantum information science, providing crucial theoretical foundations for advances in quantum computing, simulation and communications," he said [12]. Those areas match the three strands the report describes: the trapped-ion computer proposal [5], many-body simulators [6] and the quantum repeater [7].
Cirac was born in Barcelona in 1965, took his PhD at the Complutense University of Madrid in 1991 and moved to the Leopold-Franzens University of Innsbruck in 1996 [13]. He told Physics World he is "deeply honoured" [8]. Of the people behind the prize he said "it's a team working for many years" [9].
What to watch
- A head-to-head comparison of trapped-ion machines with other platforms on scale and error rates would show what 'leading' means in practice.
- Whether the IOP's own materials credit Peter Zoller, who co-developed the proposal, since the medal goes to Cirac alone.

Ignacio Cirac of the Max Planck Institute of Quantum Optics in Garching, Germany, has won the 2026 Isaac Newton Medal and Prize.
- [2]
The award citation praises Cirac's "pioneering contributions that founded modern quantum information science, uniting profound theoretical insight, experimental vision, and exceptional scientific leadership shaping quantum physics and technology worldwide".
- [3]
The medal is presented by the Institute of Physics (IOP), which publishes Physics World, and is given annually for "world-leading contributions to physics by an individual of any nationality".
- [4]
Cirac is best known for his work in the 1990s in which he co-developed a proposal for building a quantum computer using trapped ions with Peter Zoller.
- [5]
Physics World says the Cirac-Zoller proposal provided an experimentally plausible route from the theoretical idea of a quantum computer to an actual machine, with trapped ions remaining one of the leading quantum-computing platforms today.
- [6]
Cirac also showed how controlled quantum many-body systems can act as simulators to solve difficult problems in physics, chemistry and materials science.
- [7]
Cirac and collaborators pioneered long-distance quantum communication, including the idea of a quantum repeater, which distributes entanglement across distances despite losses and imperfections.
- [8]
Cirac told Physics World that he is "deeply honoured" to receive the award.
- [9]
Cirac said of the people who made the prize possible: "it's a team working for many years".
- [10]
Cirac's other honours include the Wolf Prize in Physics in 2013, the Max Planck Medal in 2018 and the inaugural ICTP-IBM Richard Feynman Prize in Quantum Computing.
- [11]
IOP president Paul Howarth called Cirac "hugely deserving" of the award and said his influence can be seen not only in the development of quantum science but "in the generation of researchers who have followed".
- [12]
Howarth said: "Professor Cirac's pioneering work has helped shape modern quantum information science, providing crucial theoretical foundations for advances in quantum computing, simulation and communications,"
- [13]
Cirac was born in 1965 in Barcelona, earned a PhD in physics from the Complutense University of Madrid in 1991, and moved to Leopold-Franzens University of Innsbruck in 1996.
