Computer applications and quantitative methods in archaeology CAA95.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

The worldwide race to the quantum computer is in full swing. This computer can bring about a breakthrough in discovering medicines and new materials. Leiden researchers, together with the TU Delft, are taking part in the race. There is now a dossier online about their work.

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.

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.

Leiden University and the Beijing Institute of Technology will be collaborating in the area of computer science teaching and research. One of the first outcomes of this collaboration will be a joint four-year bachelor's programme. Willem te Beest, Vice-President of the Executive Board, and Professor…

An international committee has assessed computer science research at all Dutch universities in the period 2009-2014. For its computer science research, Leiden was awarded the ‘highest’ mark (1) for relevance to society.

Vera van Noort has been appointed Professor in the field of Computational Biology within the Faculty of Science at the Institute of Biology from the 1st of February 2017. Van Noort’s expertise is in bioinformatics and her research focuses on the computational analysis of large-scale biological data…

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

This thesis addresses questions on effectively using variational quantum circuits for machine learning tasks.

A full overview of all loans and debts between banks would help preventing a new financial collapse. But banks do not provide this information. An econophysics model by Diego Garlaschelli and collaborators reconstructs the most probable situation and finishes first place in two independent tests.

Leiden prof. emeritus Grzegorz Rozenberg is honoured with the first life time award in formal languages, a research area of theoretical computer science. During a small ceremony at his house, he received a statue that was specially made for the occasion.

The STW project Energy Efficient Computer-Brain Interaction (principal investigator for LIACS: dr. T.P. Stefanov) has been granted. Funding for LIACS: 1 PhD student + travel/equipment budget, project duration: 4 years.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

A new study in Nature Plants has explored the most important organising principles that control vegetation behaviour. The insights from this study can be used to improve predictions on climate change. Leiden scientists Peter van Bodegom and Nadia Soudzilovskaia participated in the study.

This project is a collaboration between Sanquin, LUMC and LIACS. It focuses on the development of meta-modelling methods and tools for the exchange, analysis, and publication of anonymised patient data. Measures are being constructed to evaluate both the level of privacy and the extent to which an anonymized…

On 6 June 2019, Edward Donelan defended his thesis 'Regulatory Management Policies and a Universal Model for Public Policy Making, Legislative Drafting and Managing Stocks of Legislation'. The doctoral research was supervised by Prof. W.J.M. Voermans.

The kidneys play a major role in the elimination of drugs. In children, the exact age-related physiological changes underlying kidney function remain largely unknown.

The Digital Archaeology research group manages two computer laboratories with different purposes: the teaching lab (F1.01) and the research lab (A1.13a).

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.
