Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. This is a crucial step towards realizing a quantum repeater for high-dimensional entangled states.
A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3-D rendering methods.
Whispering gallery mode resonators rely on a phenomenon similar to an effect observed in circular galleries, and the same phenomenon applies to light. When light is stored in ring-shaped or spherical active resonators, the waves superimpose in such a way that it can result in laser light. This week in APL Photonics, investigators report a new type of dye-doped WGM micro-laser that produces light with tunable wavelengths.
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. A survey at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.
Researchers from the Moscow Institute of Physics and Technology and the University of Siegen have explained the mechanism of single-photon generation in diamond diodes. Their findings open up new avenues for the development of high-speed single-photon sources for quantum communication networks and quantum computers of the future.
An international team of scientists presents a thorough review on quantum machine learning, its current status and future prospects. The reports contrasts machine learning using classical and quantum resources, identifying opportunities that quantum computing brings to this field.

Researchers at the University of Pennsylvania demonstrated a new packing of glass with unique optical properties. What they learned could lead to innovations in technology, such as glass with different mechanical properties, and may elucidate some fundamental aspects of glass formation.
Scientists at the National Institute of Standards and Technology (NIST) have developed a laboratory instrument that will greatly reduce the cost of analyzing carbon isotopes. Among other things, this will allow scientists to measure how much of the carbon dioxide in the atmosphere came from burning fossil fuels, and to estimate fossil fuel emissions in an area as small as a city or as large as a continent.
Researchers have developed new software that makes it possible to use low-cost, thermal cameras attached to mobile phones to track how fast a person is breathing. This type of mobile thermal imaging could be used for monitoring breathing problems in elderly people living alone, people suspected of having sleep apnea or babies at risk for sudden infant death syndrome.
