In this review we consider the progress made and the remaining challenges in developing diamond-based nodes for quantum networks. We focus on the nitrogen-vacancy and silicon-vacancy colour centres, which have demonstrated many of the necessary attributes for these applications. We focus in ...
This is important for an upcoming quantum internet because it enables network-based scaling where calculations are distributed across multiple quantum computers. Solve real problems But the ambitions of PhotoQ go beyond the quantum technological core innovation. In parallel with the hardware development,...

The first quantum technology that harnesses quantum mechanical effects for its core operation has arrived in the form of commercially available quantum key distribution systems. This technology achieves enhanced security by encoding information in photons such that an eavesdropper in the system can be det...

Ronald Hanson, one of the founders of the Dutch QuTech institute, has tested quantum repeaters based on NV centers, which were not that effective. The system delivered entangled photons about every second. “We’re already working on next generation platforms that we believe can be made more ef...
Abstract:High-performance solid-state quantum sources in the telecom band are of paramount importance for long-distance quantum communications and the quantum Internet by taking advantage of a low-loss optical fiber network. Here, we demonstrate bright telecom-wavelength single-photon sources based on ...
Interviewed four people who have founded companies based on new photonics technologies developed in their research. They range in age from 34 to 49, a
and true time delay beamforming. The implementation of microwave photonic systems based on photonic integrated circuits is also reviewed, including the design, fabrication, and material platforms, application-specific photonic integrated circuits for microwave photonics, and programmable integrated microwave ph...
An overview is given of the state-of-the-art research into secure communication based on quantum cryptography. The present security model together with its assumptions, strengths and weaknesses is discussed. Recent experimental progress and remaining cha
