Scientists create first transistor with petahertz speed in the world

Scientists at the University of Arizona report that they created the world’s first quantum transistor that reaches processing speeds in the Petahertz Order. That is, thousands of times faster than current components, which operate in the Gigahertz house.

The advances were published in an article in Nature Communications, in a work signed by several researchers. Among them, Professor Mohammed Hassan, who talked about the project in a post from the University of Arizona itself.

“We have experienced a huge leap in the development of technologies such as artificial intelligence software, but the speed of hardware development does not move so quickly,” the scientist said. “But when supporting the discovery of quantum computers, we can create hardware that reaches the current revolution in information technology software. Ultra -rare computers will greatly help discoveries in space research, chemistry, health and more.”

The first Petahertz performance transistor was obtained using ultra -rare light pulses to control the movement of electron in graphene. The team tested modifications on different graphene samples when it discovered the “tunneling” effect and decided to explore the event more.

Transistor reaches PETAHERTZ in environmental conditions

Usually scientific advances in laboratories take a long time to result in practical uses of new technologies, but the first quantum transistor operating in the Petahertz Order may not be so far from a finished product.

This is because the modification was made from a commercially available graphene transistor, only improved with a special layer of silicon. And most importantly, no great conditions of the environment were required to ensure its operation. Petahertz operation was achieved in a normal everyday situation at room temperature.

Scientists already work to patent and market technology. Meanwhile, the next step is to make the transistor work with non -customized advanced lasers, which are already commercially available.
