Delft, The Netherlands: Quantum Internet Alliance (QIA) researchers at TU Delft, QuTech, University of Innsbruck, INRIA and CNRS recently announced the creation of the first operating system designed for quantum networks: QNodeOS. The research, published in Nature, marks a major step forward in transforming quantum networking from a theoretical concept to a practical technology that could revolutionize the future of the internet.

Quantum Brilliance (QB), a global leader in mass deployable, room temperature diamond quantum technology, today announced that it raised USD $20 million in its Series A funding round to accelerate the company’s mission to deliver quantum devices for applications across sectors.

Quantum sensors pave the way for innovation in sensing technology. They are set to revolutionise a variety of sectors, spanning from health care to space and defence. VTT Technical Research Centre of Finland is at the forefront of quantum sensor development, aiming to commercialise the technology for the benefit of many. The research institute strongly believes that broader adoption of quantum technologies has a strong and positive societal and environmental impact.

Lower cooling requirements, longer operating times, lower error rates: Quantum computers based on spin photons and diamond promise significant advantages over competing quantum computing technologies. The consortium of the BMBF project SPINNING coordinated by Fraunhofer IAF has succeeded in decisively advancing the development of spin-photon-based quantum computers. On October 22 and 23, 2024, the partners presented the interim project results at the mid-term meeting of the BMBF funding measure Quantum Computer Demonstration Setups in Berlin.

The Agentur für Innovation in der Cybersicherheit GmbH (Cyberagentur) has today signed contracts with three international technology companies to develop mobile quantum computers. With an investment of over 35 million euros, this project marks a milestone in quantum research and lays the foundation for new fields of application for quantum computers. The aim is to enable mobile use in security and defence scenarios as well as in civilian applications.

Researchers at TMOS, the ARC Centre of Excellence for Transformative Meta-Optical Systems, and their collaborators at RMIT University have developed a new 2D quantum sensing chip using hexagonal boron nitride (hBN) that can simultaneously detect temperature anomalies and magnetic field in any direction in a new, groundbreaking thin-film format.

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG), as reported by scientists from Tokyo Tech. The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.

That’s exactly what Harvard physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world’s longest fiber distance between two quantum memory nodes. Think of it as a simple, closed internet carrying a signal encoded not by classical bits like the existing internet, but by perfectly secure, individual particles of light.

Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.

Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.
