The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors.

Quantum computers, on the other hand, promise to rapidly crack complex cryptographic systems that a classical computer might never be able to unravel. This promise is based on a quantum factoring algorithm proposed in 1994 by Peter Shor, who is now a professor at MIT.

But while researchers have taken great strides in the last 30 years, scientists have yet to build a quantum computer powerful enough to run Shor’s algorithm.

As some researchers work to build larger quantum computers, others have been trying to improve Shor’s algorithm so it co...

Transistors, the building blocks of integrated circuits, face growing challenges as their size decreases. Developing transistors that use novel operating principles has become crucial to enhancing circuit performance.

Hot carrier transistors, which utilize the excess kinetic energy of carriers, have the potential to improve the speed and functionality of transistors. However, their performance has been limited by how hot carriers have traditionally been generated.

A team of researchers led by Prof. Liu Chi, Prof. Sun Dongming, and Prof...

Australia on Wednesday approved plans for a massive solar and battery farm that would export energy to Singapore, a project it calls the “largest solar precinct in the world”.

Authorities announced environmental approvals for SunCable’s US$24 billion project in Australia’s remote north that is slated to power 3million homes.

The project, which will include an array of panels, batteries and, eventually, a cable linking Australia with Singapore, is backed by tech billionaire and green activist Mike Cannon-Brookes.

“It will be the largest solar precinct in the world –- and heralds Austral...
