    Integrated Approach Emits Quantum Light on Demand, at Room Temperature

    Article obtained from Photonics RSS Feed.

    An integrated approach that uses a single-photon emitter embedded in a photonic waveguide, developed by researchers at KTH Royal Institute of Technology, could enable the transmission of large-scale quantum information over fiber optic networks. The KTH method emits photons in a deterministic (rather than probabilistic) fashion to deliver qubits on demand.

    The new approach bypasses the need for extreme refrigeration to provide high-quality light at room temperature.

    In the work, the researchers coupled hexagonal boron nitride (hBN) single-photon emitters to silicon nitride (SiN) waveguides and, from there, developed a way to image the quantum emitters. They activated the emitters on thermal silicon dioxide (SiO2), then…
