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.

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.

Zero Resistance Breakthrough: Meet the Quantum Sandwich Powering the Future

Posted by in categories: computing, quantum physics

Researchers have developed a new “sandwich” structure material that exhibits the quantum anomalous Hall effect, enabling electrons to travel with almost no resistance at higher temperatures.

This breakthrough could significantly enhance computing power while dramatically reducing energy consumption. The structure is based on a layered approach with bismuth telluride and manganese bismuth telluride, promising faster and more efficient future electronic devices.
