The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

This master’s programme combines Physics with Data Science. You will learn how physics has its own tricks to deal with big data and how techniques from machine learning and deep learning can be applied to classical and quantum data. The first focus of attention is on classical data, including data mining,…

Kaveh Lahabi's lab explores the exotic physics of quantum materials, whose underlying physics seems to have more in common with elementary particles and black holes, than ordinary metals and semiconductors.

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

If you are about to embark on a master’s in Leiden and the city and university are completely new to you, you should seriously consider participating an introduction week.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

The master’s specialisation Research in Physics, Quantum Matter and Optics at Leiden University offers a thorough experience on the front line of physics research with a practical training of communicative and computer skills. The programme focuses on Condensed Matter problems, such as Molecular Electronics,…

Machine learning - on classical computers- has made great progress in the past five years. Computer translation of speech and text is just one example. In Leiden, some researchers expect that machine learning, empowered by quantum systems, even if they only contain a few dozen qubits, can lead to a…

Advancing the understanding of the interaction of light and matter on the single-quantum level is important for near-future quantum technologies but also to answer fundamental questions.

Quantum critical metals at vanishing fermion flavor number.

We explore the possibilities to combine magnetic resonance techniques with atomic force microscopy together in a single microscope: the MRI-AFM, also called Magnetic Resonance Force Microscopy (MRFM).

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

This thesis described the development of novel scanning tunneling microscopy techniques to investigate strongly correlated electronic states in quantum matter.

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

The studies in this thesis are focused on the physical effects in the flat band materials. The results contain the discovery of strong enhancement of RKKY spin-spin interactions with specific geometric arrangement and dynamical generation of excitonic order parameter with high magnitude.

If you are about to embark on a master’s at Leiden University in The Hague and both the city and the University are new to you, consider participating in The HOP. This introduction week has been specially designed to help new students get acquainted with the city and its student life.

In our lab, we investigate the physics and material properties of low-dimensional systems.

Will you be studying in Leiden University in The Hague? If so, join in the HOP introduction week and get acquainted with the city and its student life.

Do you want to get your stay in Leiden or The Hague off to the best-possible start? If so, you cannot afford to miss Leiden University’s introduction weeks for international students. In addition to having lots of fun, you’ll make new friends and start getting to know the University and the city.

Do you want to get your stay in Leiden off to the best possible start? Then you cannot afford to miss OWL, Leiden University’s introduction week for international students. In addition to having lots of fun, you’ll make new friendships and start getting to know the University and the city.

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

As an exchange or study abroad student at Leiden University, you will generally follow a selection of taught courses in Leiden or the Hague. In some circumstances, it is also possible to do a project, internship or research.

Can we use quantum computers in a way that is also relevant to society? With the help of a 2-million-euro NWA grant, Leiden University will work with partners such as Surf, Google and Volkswagen to demonstrate that quantum computers are also of value outside the lab.

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

The research in my group addresses a range of topics related to quantum many-body physics.

Friday afternoon, 1 October. Location: one of the most vibration-free places in the world. In this setting, Leiden top scientists launched Quantum Leiden. For decades, researchers at the Faculty of Science have been investigating quantum technology at the highest level and also have been brainstorming…

With defending his thesis ‘Applications of topology to Weyl semimetals and quantum computing’, the Leiden theoretical physicist Tom O'Brien has gained the rare 'cum laude' qualification. The freshly minted PhD has started a five year research programme on quantum algorithms for quantum chemistry, funded…

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…
