The search for a ‘quantum advantage’
Proving a quantum computer to be quicker than a normal one is one step closer. After a breakthrough in speeding up classical algorithms, researchers Vedran Dunjko and Casper Gyurik showed that only one quantum algorithm could beat its classical counterpart. They discuss their discovery in Quanta Mag…

Tricking a quantum computer to enhance its performance
Researchers found a way to run programmes that should be impossible to carry out on an imperfect quantum computer. Such programmes are very computationally demanding and the quantum computers that currently exist are not yet up to that task. Unless you use a clever trick, Simon Marshall and Vedran Dunjko…

Physics in the picture: cancer cells as an explosion of fireworks
When you think of physics, do you think only of complicated formulas? You’re not the only one. Therefore, every year, the Leiden Insitute of Physics organises the LION Image Award to show another side of physics: beautiful images about intriguing science. The winner of the 2022 photo competition captured…

How quantum mechanics threatens our digital lives – and makes them safer
Much of the work of Serge Fehr, Professor of Quantum Information Theory, is abstract and theoretical and comprehensible to very few people. But his work helps make the digital world safer so that in future our internet banking will still be problem free, for instance. He will explain more in his inaugural…

The quantum computer: it doesn't exist yet, but still we understand increasingly better what problems it can solve
How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.

New perspective in quantum mechanics and better sleep for PhD students
Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

Post-quantum cryptography should keep our DigiD, bank accounts and state secrets safe
Our banking, DigiD and sensitive medical data: what if our entire digital infrastructure can no longer be trusted? Jelle Don has this question permanently in mind as he goes about his research. And that is no bad thing because without new digital security measures, our society will be extremely vuln…
