Our work on quantum secure authentication is out!
Fraud-proof credit cards possible with quantum physics Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial data and personal information from criminal activity. Fortunately, new insights into quantum physics may soon offer a solution.

Nos félicitations!
Winnaars Descartes-Huygensprijs bekend De Nederlandse natuurkundige Willem Vos en zijn Franse collega Ludwik Leibler ontvangen op 26 januari de Descartes-Huygensprijs in Amsterdam.
Open source wavefront shaping!
In a next step to bring wavefront shaping to the world, we're making our software open source.
http://cops.nano-cops.com/news/cops-open-source-software-available
You can download our software from SourceForge (and contribute your own extensions if you like). An open access preprint on Arxiv describes the internal workings.
We're planning to make all new software developed under NWO and EU contracts open source. What's your opinion?
COPS open source software available | Complex Photonic Systems COPS software for controlling the phase and amplitude of light using a binary amplitude device is now available. It combines binary ("on/off") pixels into small groups, called superpixels, which have full control over the light field. Curious about our software?

'Beveiliging chip pinpas is lek' De chip op de huidige pinpas, de zogenoemde EMV-chip, blijkt door een lek te kopiëren. De chip is juist ingevoerd om skimem tegen te gaan.

Computer Laboratory – Security Group: Tamper resistance of Chip & PIN (EMV) terminals We demonstrate how fraudsters could collect card details and PINs, despite the victims taking all due care to protect their information. This means that customers should not automatically be considered liable for fraud, simply because the PIN was used. Even though a customer's PIN might have been co…
