Researchers at California Institute of Technology have explored how topology can endow special properties to a photonic platform in which superconducting qubits are embedded in a waveguide.
The researchers showed that this configuration produces topological states in the waveguide and observed an imprint of this topological behavior in a directional coupling between qubits. The coherent transfer of the state of one qubit to the other via the topological states also suggests that the scheme might have potential in quantum information. (APS Physics)
