... using Spins and Topological Quantum Systems
Recently, there are exciting breakthroughs in quantum information science. However, quantum systems suffer from decoherence due to the unavoidable system-environment interaction, which poses a major obstacle to quantum information applications. Nevertheless, conventional quantum systems like spins can be protected from decoherence via dynamical decoupling. I will present some recent results of diamond-based spin systems that can be used for high-resolution nano-magnetometers and room-temperature quantum computers. Another promising approach to suppress decoherence is to use topological quantum systems, which emerge from condensed matter physics and are insensitive to local perturbations. I will discuss some new ideas to create and probe topological quantum systems, and propose a hybrid platform between topological and conventional quantum systems that can combine the advantages from both.
