Fossil study brings us one step closer to revealing how 'flying dinosaurs' took flight. Jan 17, 2024. WebJan 25, 2024 · The qubits, whose photon-emission frequencies are tunable, interact with the photonic states of the waveguide. When a qubit’s frequency falls within the band gap, there are no propagating modes to which the quibit excitation can couple. As a result, the excitation creates a “bound state” that remains localized around the qubit (Fig. 1 ).
