$7 billion “city within a city” planned for Phoenix

Posted by in categories: computing, economics, employment, engineering

“Our vision is for chip designers and engineering students, not just suppliers and manufacturers, to co-locate here, to create a value added ecosystem beyond just what it takes to build chips, and that’s how we’re going to create more value in the Phoenix economy,” Mack said.

A further three plants are also planned for the Phoenix site, which could bring TSMC’s total investment in the area to over $120 billion. Tech giant Apple has announced it will buy semiconductors from the fabrication plants.

The plants are anticipated to create 10,000 permanent jobs, and another 80,000 are expected to be created in the surrounding development.

Solving computationally hard problems with 3D integrated photonics

Posted by in categories: biotech/medical, computing, transportation

As technology advances, the limitations of conventional electronic computers are becoming increasingly apparent, especially when tackling complex computational challenges. NP-complete problems, which grow exponentially with size, represent some of the toughest puzzles in computer science. These issues have significant implications across various fields, including biomedicine, transportation, and manufacturing. In the quest for more effective…

Computer Scientists Establish the Best Way to Traverse a Graph

Posted by in categories: computing, information science

A new proof shows that an upgraded version of the 70-year-old Dijkstra’s algorithm reigns supreme: It finds the most efficient pathways through any graph.

It doesn’t just tell you the fastest route to one destination.


In an interview toward the end of his life, Dijkstra credited his algorithm’s enduring appeal in part to its unusual origin story. “Without pencil and paper you are almost forced to avoid all avoidable complexities,” he said.

Unlocking the 3D Spin Secrets of Magnetic Skyrmions To Power Future Electronics

Posted by in categories: computing, nanotechnology

Researchers at Berkeley Lab have advanced the understanding of magnetic skyrmions by developing techniques to image their 3D structures.

These nanoscale objects show promise for revolutionizing microelectronics through enhanced data storage capabilities and reduced energy consumption.

A difficult-to-describe nanoscale structure called the magnetic skyrmion holds potential for creating advanced microelectronic devices, including those with vast data storage capacities and significantly lower power requirements.

Researchers use magnetic fields to freeze light in its tracks

Posted by in categories: computing, particle physics

This finding, achieved independently by a team at Pennsylvania State University published in the same journal, holds immense potential for the development of nanophotonic devices.

Manipulating the flow of light in materials at small scales is crucial for creating efficient nanophotonic chips, the building blocks for future optical devices. In the realm of electronics, scientists can control the movement of electrons using magnetic fields.

The Lorentz force, exerted by the magnetic field, dictates the electron’s trajectory. However, this approach is inapplicable to photons – the fundamental particles of light – as they lack an electrical charge.

New deep ultraviolet micro-LED array advances maskless photolithography

Posted by in category: computing

A team led by Prof. Sun Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then applied in deep ultraviolet (DUV) maskless photolithography system for the first time. Their study was published in Laser & Photonics Reviews.

Researchers use high-performance computing to analyze a quantum photonics experiment

Posted by in categories: computing, quantum physics

For the first time ever, scientists at Paderborn University have used high-performance computing (HPC) at large scales to analyze a quantum photonics experiment. In specific terms, this involved the tomographic reconstruction of experimental data from a quantum detector. This is a device that measures individual photons.
