Omnitron Sensors, which makes MEMS sensor chips, has raised $13 million to create inexpensive sensors for self-driving cars.

Scientists want to define the kilogram by gravity—and not just electricity. Here's why correctly quantifying mass is more important than you think.

Researchers have used atoms trapped by light to sustain quantum superposition. The cat is both dead and alive.

The thinness of silicon wafers is important because it reduces resistance and power loss. Current-gen wafers measure 40 to 60 micrometers thick. By roughly halving the wafer's...

Next step: figure out what to do with it.

A new study by a collaborative team from the University of Twente and the e-Science Center in Amsterdam compares the transmission of light through a utopian model with a real 3D nanostructure. These nanostructures are integral to our daily technologies, such as smartphones and solar panels.

How this new discipline is driving efficiency, innovation, and safety in everything from manufacturing to infrastructure.

MIT spinout Optigon aims to rev up the energy transition by using laser-based precision tools for measuring and tuning solar materials to dramatically speed up the optimization of photovoltaics.

Researchers from the University of Portsmouth have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.

Understanding the behavior of matter is crucial for advancing scientific fields like biology, chemistry, and materials science. X-ray crystallography has been instrumental in this pursuit, allowing scientists to determine molecular structures with precision.

Counterfeiting of various documents, banknotes, or tickets is a common problem that can be encountered in everyday life, even when shopping. Recognizing the scale and seriousness of the problem, researchers at Kaunas University of Technology (KTU), Lithuania, decided to look for ways to further reduce the risk of counterfeiting by inventing a new method to produce holographic security labels.

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of JILA researchers—headed by JILA Fellows and University of Colorado Boulder professors Margaret Murnane and…

The long-term vision for quantum computing is the ability to leverage millions of noise-free qubits to address selected problems that are hard to solve with classical computers. Application fields that may benefit from this technology include materials synthesis, pharmaceutical drug development, and cybersecurity, to name a few.

Optical metrology, as a general-purpose metrology technique that uses light as information carriers for non-contact and non-destructive measurement, is fundamental to manufacturing, basic research, and engineering applications.

Yuan-Yu Jau is on a quest to build the world's smallest atomic clock, a device that measures time with extreme accuracy. If successful, he and his team at Sandia will have made one smaller than a sugar cube.

Over the past decades, physicists and engineers have been trying to develop various technologies that leverage quantum mechanical effects, including quantum microscopes. These are microscopy tools that can be used to study the properties of quantum particles and quantum states in depth.

At SemiCon West, it has been announced that the Silicon Valley based company Solarius has become part of the Marposs Group, strengthening the technology of the Italian multinational company in the semiconductor industry

Researchers report a new single-photon Raman lidar system in Applied Optics that operates underwater and can remotely distinguish various substances. They also show that the new system can detect the thickness of the oil underwater up to 12 m away, which could be useful for detecting oil spills.
