Programming on a silicon quantum chip
Quantum technology makes a great leap forward. While scientists can control a few qubits with great reliability, it doesn’t yet look like a real computer. Useful quantum chips require programmability: the ability to perform an arbitrary set of operations. Scientists from QuTech in Delft have now realised a programmable two-qubit quantum processor in silicon successfully implementing two quantum algorithms. They have published their work in the magazine Nature.
Designing and testing medical instruments without expensive prototypes
Complex new medical instruments often do not make it beyond the expensive and time-consuming prototype phase. With this in mind, Ewout Arkenbout developed a new, virtual development method allowing for instruments to be evaluated and adjusted at an earlier stage. On Monday 12 February, Arkenbout will be awarded his PhD at TU Delft for his work on this subject.
Mathematics explains why Crispr-Cas9 sometimes cuts the wrong DNA
The discovery of the Cas9 protein has been of great value to medical science. It has simplified gene editing tremendously, and may even make it possible to eliminate many hereditary diseases in the near future. Using Cas9, researchers have the ability to cut DNA in a cell to correct mutated genes, or paste new pieces of genetic material into the newly opened spot. Initially, the Crispr-Cas9 system seemed to be extremely accurate. But unfortunately, it is now apparent that Cas9 sometimes also cuts other DNA sequences similar to the exact sequences it was programmed to target. Scientists at Delft University of Technology have developed a mathematical model that explains why Cas9 cuts some DNA sequences while leaving others alone.
The quest to find the optimal speed skating technique
In her search to determine the optimal speed skating technique, doctoral candidate Eline van der Kruk developed a dynamic computer model of a skater and instrumented clap skates. In the future, these will make it possible to offer skaters and coaches real-time visual feedback during training sessions. On Thursday 8 February, the day before the start of the Winter Olympics, Van der Kruk will be awarded her PhD at TU Delft for her work on this subject.
