COPS at the 10th ANP retreat
The group of all UT opticians, Applied NanoPhotonics (ANP) gathered for its 10th retreat at the castle in Coevorden to inform each other on recent developments in nanophotonics. Two invited external speakers, Alex Szameit (Rostock) and Bart Kuyken (Ghent) gave excellent lectures on topological photonics and on frequency-comb generation. COPS was well represented by talks […]

New Bachelor students join COPS
Recently, Lars van der Hoeven en Jasper van den Hoogen have started their bachelor projects. Lars is currently working under the guidance of Prof. Dr. Pepijn W. H. Pinkse and master student Matthijs Velsink. The thesis revolves around the use of a multimode fibre (MMF) as a physical unclonable function applicable in quantum encryption methods […]

Light proceeds by jumps on a lattice in new 3D photonic nanostructures
Scientists at the University of Twente have developed a physical model for light propagation at the nanoscale in new 3D cavity superlattices. Such 3D cavity superlattices are of interest for studying nanophotonic phase transitions, and also have applications for quantum computers. The results have been published on 12 March 2019 in the leading physics journal […]

Mikado in a nano box
Date: 25 Apr 2019 When you shake a box filled with Mikado sticks, will you get a uniform spreading of the sticks inside the box? This question touches Bertrand’s paradox, a classic in mathematics. In 2D, this is already an intriguing question, so what if you move to 3D? And, to make it more complex, […]

Putting Photons in Jail
Scientists at the University of Twente have discovered a novel type of resonant nanocavity that serves as a “jail for photons“. The cavity confines light in all three dimensions (3D) simultaneously by exploiting a surrounding photonic band gap crystal nanostructure as the 3D jail’s bars. The 3D confinement of photons in tiny volumes in space […]

COPS scientists found quantum startup QuiX
Cops scientists Ad Lagendijk, Willem Vos, Pepijn Pinkse, and Jelmer Renema together with Klaus Boller (LPNO) have teamed up to create the startup QuiX, “the fastest way to a quantum future”. QuiX’s goal is to build the first quantum photonic processor based on silicon nitride waveguides. QuiX was launched with support of the pre-seed investor RAPH2INVEST. CTO Jelmer […]

Landauer’s erasure principle in a squeezed thermal memory
Energy dissipation is a key design factor in digital electronics. Improvements in our understanding of energy dissipation in information-processing devices are of high scientific and technological interest. In 1961, Rolf Landauer argued that there exists a limit to which the power consumption of an erasure operation in a computer memory can be reduced. Fundamental to […]
