• Description

  Quantum processors promise to deliver enormous computational power for solving problems which lie beyond the capabilities of classical machines. There are many hardware platforms on which quantum computing can be developed, and it is not yet clear which technological approach will prove most successful. Photonic technologies face challenges because of the need to generate and transform the required quantum states on demand.

  Integrated quantum photonic circuits provide a viable route for the generation, manipulation, and detection of quantum states of light in miniaturized waveguide circuits. Implementation of these three operations in a single integrated platform is a crucial step toward a fully scalable approach to quantum photonic technologies. Diamond has emerged as a particularly promising material as it naturally combines a large transparency range for the fabrication of low-loss photonic circuits, and a variety of optically active defects for the realization of efficient single-photon emitters.

  This symposium focusses on the opportunities and challenges of diamond-based integrated quantum photonic architectures. Implementations, physics and applications of diamond components for quantum technologies will be discussed.
