I’m fascinated by quantum physics, both fundamental aspects as well as applied quantum technology. One example of an interesting fundamental effect is the dynamical Casimir effect, where photons are created out of the vacuum by a mirror accelerating to velocities close to the speed of light. A more applied question is how to build a quantum computer, where the quantum mechanical phenomena superposition and entanglement are used to solve problems that are beyond the capabilities of today’s supercomputers. A working quantum computer can find detailed properties of large biological molecules, which can lead to new medicines and other novel medical treatments. A quantum computer could also enhance artificial intelligence and gives us qualitatively new possibilities to find structures in large set of data and find better solutions to optimization problems, such as traffic control to avoid congestions.
