Tags: Tokyo Institute of Technology, Japan, Computing Technology, Science & Exploration
Researchers at Tokyo Tech have successfully tuned the Chern number, an invariant quantity characterizing topological phases, in the nitrogen-vacancy (NV) center in diamond. By manipulating an electronic-nuclear spin system, they observed Chern numbers ranging from zero to three, enabling the exploration of exotic topological phases. This breakthrough offers potential applications in topological quantum information and low-power-consumption electronics. The team's findings align with numerical simulations, demonstrating controllability and opening avenues for practical implementations. The ability to access higher Chern numbers in this system paves the way for advancements in quantum metrology, spintronics, and quantum computation.
