Nano-Diamond Qubits And Photonic Crystals
Milestone reached on the path to integrated quantum technology
Quantum information processing is arguably one of the most fascinating facets of modern quantum physics.
Now, researchers in Germany have successfully fabricated a rudimentary quantum computing hybrid system using electronic excitations in nano-diamonds as qubits and optical nanostructures, so-called photonic crystals with tailored optical properties. This architecture may allow integration of multi-qubit systems on a single micrometer-sized chip for future quantum computers.
"Our results suggest a strategy for scaling up quantum information to large-scale systems, which has yet to be done," says Janik Wolters, researcher, at Humboldt Universität in Berlin. "We regard our experiment as a milestone on the long road toward on-chip integrated quantum information processing systems, bringing the dream of a quantum computer closer to reality."
