Researchers at HP (Quote, Chart) have come up with a new signal technology they claim could replace transistors in computers one day.

In a paper published in Tuesday's Journal of Applied Physics, three members of HP Labs' Quantum Science Research (QSR) group demonstrated what they call a "crossbar latch."

A latch consists of a single wire acting as a signal line, crossed by two control lines with an electrically switchable nanoscale junction where they intersect. The technology is so small, HP claims thousands of the strands could fit across the diameter of a human hair.

"We are re-inventing the computer at the molecular scale," Stan Williams, HP senior fellow, QSR director and one of the authors of the paper, said in a statement. "The crossbar latch provides a key element needed for building a computer using nanometer-sized devices that are relatively inexpensive and easy to build."

Similar to the way that silicon-based transistors perform in computers today, the researchers said the crossbar latches use a sequence of voltage impulses to the control lines and using switches arranged in opposite polarities.
