When the team fired their ultra-fast laser at a graphene wire strung between two gold electrodes, it produced two different kinds of currents. Some of the electrons excited by the light continued moving in a particular direction once the light was switched off, while others were transient and were only in motion while the light was on. The researchers found that they could control the type of current created by altering the shape of their laser pulses, which was then used as the basis of their logic gate.

Logic gates work by taking two inputs—either 1 or 0—processing them, and providing a single output. The exact processing rules depend on the kind of logic gate implementing them, but for example, an AND gate only outputs a 1 if both its inputs are 1, otherwise it outputs a 0.

Speeding up communication between humans is surprisingly tricky.

Last week, a post by Elon Musk on X (formerly known as Twitter) caught my eye. The entrepreneur claimed that sticking electrodes in people’s heads is going to lead to a huge increase in the rate of data transfer out of, and into, human brains.

The occasion of Musk’s post was the announcement by Neuralink, his brain-computer interface (BCI) company, that it was officially seeking the first volunteer to receive the “N1,” an implant comprising 1,024 electrodes able to listen in on brain neurons.

Wouldn’t it be great if researchers could use a special quantum eraser to remove their mistakes?

NEC Corporation has developed a 150 GHz transmitter IC chip and supporting technologies in preparation for Beyond 5G and 6G mobile access radio communication systems. According to an NEC survey, this is the first demonstration of preferred beam steering performance with 4-channel Antenna-on-Chip (AoC) IC technology using On the Air (OTA) radiation pattern measurement.

Based on innovative RF circuit design technology, it has become possible to integrate 150 GHz phased array antenna elements, phase shifters and transmission amplifiers into a single chip. The 22-nm SOI-CMOS technology used for manufacturing this IC is cost effective, suitable for mass production, and has the ability to support large scale integration of digital, analog and RF functionalities in a chip.

This allows for both higher frequencies and smaller sizes, which also contributes to lower Total Cost of Ownership (TCO) and potentially accelerates social implementation.

Your phone may have more than 15 billion tiny transistors packed into its microprocessor chips. The transistors are made of silicon, metals like gold and copper, and insulators that together take an electric current and convert it to 1s and 0s to communicate information and store it. The transistor materials are inorganic, basically derived from rock and metal.

But what if you could make these fundamental electronic components part biological, able to respond directly to the environment and change like living tissue?

This is what a team at Tufts University Silklab did when they created transistors replacing the insulating material with biological silk. They reported their findings in Advanced Materials.

Now, Dr. Melvin Vopson, a physicist, is following up on such a theory and investigating a new law of physics to support the idea that our reality might be a computer simulation, according to a statement by the University of Portsmouth.

Europe is pushing to create a network infrastructure based on quantum physics.

In May 2023, Dr. Benjamin Lanyon at the University of Innsbruck in Austria took an important step toward creating a new kind of internet: he transferred information along an optical fiber 50 kilometers long using the principles of quantum physics.

Information in quantum physics differs from the units of data—binary digits—stored and processed by computers that form the core of the current World Wide Web. The quantum physics realm covers the properties and interactions of molecules, atoms and even smaller particles such as electrons and photons.
