Twente will become the center of a global revolution in photonics with the development of New Origin, an advanced production facility for photonic chips. Thanks to a grant from the province of Overijssel and the involvement of regional development company Oost NL as a shareholder, the company is progressing from planning to the actual construction of the plant.

Currently, the most efficient way to create photon pairs requires sending lightwaves through a crystal large enough to see without a microscope. In a paper published today in Nature Photonics, a team led by Columbia Engineering researchers and collaborators, describe a new method for creating these photon pairs that achieves higher performance on a much smaller device using less energy. P. James Schuck, associate professor of mechanical engineering at Columbia Engineering, helped lead the research team.

A major result in quantum mechanics has been achieved: for the first time, the temporal evolution of a quantum system has been manipulated through interaction with light pulses in the extreme ultraviolet (XUV). This achievement has been obtained by a team of researchers coordinated by Prof. Lukas Bruder from the University of Freiburg, in collaboration with 14 international institutes, including the Politecnico di Milano, the Institute of Photonics and Nanotechnologies of the National Research Council of Milan (CNR-IFN), the Institute of Materials Workshop of the National Research Council of Trieste (CNR-IOM), the National Institute for Nuclear Physics (INFN), the National Laboratories of Frascati (Rome), and the Elettra Synchrotron in Trieste.

Researchers at the Indian Institute of Science (IISc), Bangalore, have have integrated two-dimensional (2D) semiconductor colloidal quantum wells (CQWs) with dielectric metasurface resonators (MSRs) to achieve unprecedented emission line narrowing and long- range photon transport at room temperature for on-chip photonic quantum information processing.

The Fraunhofer Institute for Applied Optics and Precision Engineering IOF is presenting a new photon source at SPIE Photonics West in San Francisco (January 28 to 30, 2025) that has been specially developed for the "Prepare-and-Measure" protocol of quantum communication. The components of the source are optimized for use in space.

The networked world is increasingly being shaken by digital sabotage, cyber attacks, malware and the like. Yet IT security is more important than ever these days. Networks based on quantum physics could significantly improve the security of relevant systems. So-called quantum repeaters form the basis for this. These devices have been the subject of intensive research for several years, but are not yet marketable. A new joint project, in which Paderborn University is involved, therefore aims to develop new concepts and demonstrate them on real test tracks outside the laboratory.

Quantum Computing Inc. (“QCi” or the “Company”), an innovative, integrated photonics and quantum optics technology company, today announced a collaboration with Sanders Tri-Institutional Therapeutics Discovery Institute, Inc. (Sanders TDI) to drive advancement of research in computational biomedicine. Through this collaboration, QCi will provide Sanders TDI with access to its quantum computation technology and hardware, specifically with its Dirac-3 Entropy Quantum Computing Machine, to support the Institute’s experimental work.

Quantum Computing Inc. ("QCi" or the "Company"), an innovative, integrated photonics and quantum optics technology company, today announced that it has entered into securities purchase agreements with institutional investors for the purchase and sale of 8,163,266 shares of common stock in a private placement at a purchase price of $12.25 per share. The offering is expected to result in gross proceeds of $100 million, before deducting offering expenses. The closing of the offering is expected to occur on or about January 9, 2025, subject to the satisfaction of customary closing conditions.

In a new paper in Nature Photonics, researchers at the University of Pennsylvania School of Engineering and Applied Science (Penn Engineering) describe the creation of a novel photonic switch that overcomes this size-speed tradeoff. And at just 85 by 85 micrometers, the new switch’s units are smaller than a grain of salt.

Scientists including an Oregon State University chemistry researcher have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again.
