A new path toward sending and receiving information with single photons of light has been discovered by an international team of researchers led by the University of Michigan.
Their experiment demonstrated the possibility of using an effect known as nonlinearity to modify and detect extremely weak light signals, taking advantage of distinct changes to a quantum system to advance next generation computing.
Today, as silicon-electronics-based information technology becomes increasingly throttled by heating and energy consumption, nonlinear optics is under intense investigation as a potential solution. The quantum egg carton captures and releases photons, supporting excited quantum states while it possesses the extra energy. As the energy in the system rises, it takes a bigger jump in energy to get to that next excited state that s the nonlinearity.

WEST LAFAYETTE, Ind. - IdentifySensors Biologics, a Purdue University-affiliated technology firm developing a rapid diagnostic platform for detecting pathogens, including SARS-CoV-2, has entered into a new partnership with Purdue Research Foundation and will open an office in Purdue s Discovery Park District.
As the COVID pandemic was about to break around the globe, IdentifySensors, the parent company of IdentifySensors Biologics, had approached Purdue to help them develop a nanosensor designed to detect spoilage and specific pathogens in the food supply chain.

The Pazyryk carpet is the world s oldest example of a knotted-pile carpet and is kept at the State Hermitage Museum in St. Petersburg, Russia. The carpet, which was made out of new wool at around 400 BC, is one of the most exciting examples of central Asian craftsmanship from the Iron Age. Ever since the carpet was discovered in 1947 by Russian archaeologists in a kurgan tomb in the Altai mountains, experts in traditional dyeing techniques have been puzzled by the vivid red, yellow and blue colours of the carpet, which lay buried in extreme conditions for almost two thousand five hundred years.

Much like the Jedis in Star Wars use the force to control objects from a distance, scientists can use light or optical force to move very small particles.
The inventors of this ground-breaking laser technology, known as optical tweezers , were awarded the 2018 Nobel Prize in physics.
Optical tweezers are used in biology, medicine and materials science to assemble and manipulate nanoparticles such as gold atoms. However, the technology relies on a difference in the refractive properties of the trapped particle and the surrounding environment.
Now scientists have discovered a new technique that allows them to manipulate particles that have the same refractive properties as the background environment, overcoming a fundamental technical challenge.
As light as possible and as strong as possible at the same time. These are the requirements for modern lightweight materials, such as those used in aircraft construction and the automotive industry. A research team from Helmholtz-Zentrum Geesthacht (HZG) and Hamburg University of Technology (TUHH) has now developed a new materials design approach for future ultralight materials: Nanometer-sized metal struts that form nested networks on separate hierarchical levels provide amazing strength.
