Cheap Carbon Nanodots Could Replace Toxic Metal Quantum Dots in the Future

Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they emit less light.

Researchers Find New Way to Detect Single Quantum Bit in a Dense Cloud

Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behaviour, making it possible to detect a single quantum bit in a dense cloud.

Student Astronomer Develops Method to Track Down Milky Way's Missing Matter

Astronomers have for the first time used distant galaxies as 'scintillating pins' to locate and identify a piece of the Milky Way's missing matter.

Breakthrough in Photonic Circuits Heralds a New Future for Quantum Computing, Communication

The modern world is powered by electrical circuitry on a "chip"--the semiconductor chip underpinning computers, cell phones, the internet, and other applications. In the year 2025, humans are expected to be creating 175 zettabytes (175trillion gigabytes) of new data. How can we ensure the security of sensitive data at such a high volume- And how can we address grand-challenge-like problems, from privacy and security to climate change, leveraging this data, especially given the limited capability of current computers-

Review Highlights Synthesis and Application of Graphene Quantum Dots

In a paper published in NANO, researchers from Hubei, China discuss the top-down and bottom-up strategies for the synthesis of Graphene quantum dots (GQDs). The respective advantages and disadvantages of these methods are summarized. With regard to some important or novel ones, the mechanisms are proposed for reference. In addition, the application of GQDs in biosensors is highlighted in detail.

Search for Axions From Nearby Star Betelgeuse Comes Up Empty

The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter — a hypothetical, invisible type of matter that is thought to make up 85 percent of the mass in the universe.

Researchers Achieve Significant Milestone in the Creation of a Working Quantum Computer

Quantum computer: One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers.
