Following quantum chip breakthroughs by Microsoft and Google, AWS scientists explain the role transistors play in this first-generation cat qubit architecture.

If you look at the Lumus Z-30 Optical Engine for AR glasses, it looks pretty much like an ordinary pair of glasses. But it's AR.

Here is a hands on look and full review of the new Even Realities G1 glasses. This is how smart glasses should be!

Deep Space Station 23's 133-ton reflector dish was recently installed, marking a key step in strengthening NASA's Deep Space Network.

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

It's not ready for primetime yet, but it's Meta's most ambitious AR project to date.

Researchers have created orange, yellow and green lasers tiny enough to fit on a chip.

Stanford is redefining AR with glasses that combine metasurface waveguides and AI-driven holography, offering a revolutionary way to experience digital and real-world integration. Here's what it all means.

While an expensive, bulky Vision Pro headset undoubtedly has its place for some, Apple's longer-term goal is believed to be...

If it walks like a particle, and talks like a particle… it may still not be a particle. A topological soliton is a special type of wave or dislocation that behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a po

In the realm of physics, synthetic dimensions (SDs) have emerged as one of the frontiers of active research, offering a pathway to explore phenomena in higher-dimensional spaces, beyond our conventional 3D geometrical space. The concept has garnered significant attention, especially in topological photonics, due to its potential to unlock rich physics inaccessible in traditional dimensions.

Metal halide perovskites have become well-deserved "star" materials among a variety of semiconductors owing to their excellent optoelectronic properties, such as high photoluminescence (PL) quantum yield (QY), high absorption coefficient, tunable bandgaps, long carrier diffusion lengths, and high defect tolerance, attracting enormous attention from both academia and industry.

Sallie Pero Mead made major discoveries about how electromagnetic waves propagate that allowed objects to be detected at a distance

Researchers at the University of Toronto, led by Dr. Amr S. Helmy, have developed a new method for integrating electro-optic SiO2/ITO heterointerfaces into metal–insulator–semiconductor (MIS) structures. This breakthrough is expected to lead to the development of more efficient and compact photonic devices.

Perovskite materials are still attracting a lot of interest in solar cell applications. Now, the nanostructures of perovskite materials are being considered as a new laser medium. Over the years, light amplification in perovskite quantum dots has been reported, but most of the works present inadequate quantitative analysis.

When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently reported the development of a new optical device called a turnkey frequency microcomb that has applications in digital communications, precision time keeping, spectroscopy, and even astronomy.

The past few years have seen a massive surge in the amount of data transferred and processed per second. Rapidly emerging technologies, such as high-dimensional quantum communications, large-scale neural networks, and high-capacity networks, require large bandwidths and high data transfer speeds. One plausible way to achieve them is by replacing the conventional metallic wires between the components in an…

A Game-Changer in Antenna Setup and Operational Efficiency

Six students with ties to MIT have been awarded fellowships by the Fannie and John Hertz Foundation: Jeffrey Brown, Liyam Chitayat, Vaibhav Mohanty, Sahil Pontula, Benjamin Spector, and Beatriz Yankelevich.
