The standard approach to build a quantum computer with Majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits to be converted again into so-called fermions. Physicists from Leiden and Delft suggest…

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.

Opening van het Quantum Delta NL (QDNL) Talent & Learning Centre (TLC) Leiden-Delft.

The most famous cat in science is Schrödinger's cat, the quantum mechanical mammal, which can exist in a superposition, a state that is alive as well as dead. The moment you look at it, one of both options is chosen. Leiden University physicists simulated an experiment to catch this mysterious moment…

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.

During the Bachelor Honours Class ‘The world is quantum’, students from various disciplines learned about the rules of nature on the smallest scale: quantum mechanics. What opportunities and dangers do they see for their field of study?

Over the past two years, the Physics department has been supporting high school physics education with a set of challenging quantum experiments. School classes can visit Leiden University to learn about quantum mechanics, in preparation for their final exams. As of early 2018, this lab has evolved into…

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…

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

We are interested in understanding the mechanics of soft materials, of which biological materials are prominent examples.

Three researchers from Leiden University have received awards in the Quantum Technology programme within the National Growth Fund, organised by NWO in collaboration with Quantum Delta NL. Read more about these three futuristic projects.

Quantum Delta NL, a research programme in which Leiden University participates, has been awarded 615 million euros from the National Growth Fund to help develop the Netherlands into a top player in quantum technology. This has been announced at the presentation of the honoured proposals in The Hague…

Quantum software is essential to make quantum technology work. Research centers QuSoft and aQa work together at the forefront of the Netherlands’ quantum software efforts. With the launch of the Quantum Software Alliance (QSA), this collaboration now scales globally.

American physicist and quantum computing pioneer Seth Lloyd is the 65th Lorentz professor. He will deliver the Ehrenfest lecture on 5 June, and several more lectures on quantum computing on 11, 18 and 25 June.

We investigate the physics and design of mechanical metamaterial, intricately sculpted materials with properties set by their architecture.

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

In the weekly magazine “Mare” from Leiden University, an interview with the Leiden statistics prof. dr. Richard Gill has been published recently about his contribution to the Delfts quantum-experiment.

Mass, time, space, and complexity — physicists in Leiden are launching eight new research projects tackling some of the most fundamental themes in quantum mechanics. Their goal: to push the limits of current quantum theories.
