Computer Memory Could Become Up To 1000 Times Faster With Terahertz Radiation

Terahertz Radiation, or T-rays, is capable of bringing computer memory to a completely new era. Researchers found out that using T-rays instead of a magnetic field to perform cell-resets in computer memory, the memory could work up to 1000 times faster. Terahertz radiation is still in its infancy. It occupies a radiation band placed between microwaves and infrared light, with wavelengths placed between 1 mm and 0.1 mm, with frequencies between 0.3 to 3 terahertz.


Terahertz radiation is used today in airport body scanners, and its capability to make devices see through objects was used in a research at MIT that allowed a camera (using T-rays) to read closed books. In another research, terahertz radiation was used to examine insides of a broken microchip. These two experiments are just the beginning of a widespread T-rays usage.

The newest research used terahertz radiation, instead of a classic magnet field, to switch memory cells in computer memory. And T-rays performed stellarly. Using them, scientists managed to switch memory cells in a trillionth of a second. It’s worth noting that these fantastic results were achieved inside a controlled environment, and that years could pass before the said technology becomes available for public.

The research was conducted by a team of European and Russian scientists and was published in the Nature Journal. The results were so striking that the leader of the study, Professor Rupert Huber working at the University of Regensburg, Germany, hailed the study as “a milestone of photonics.”

Since T-rays can switch memory cells 1000 times faster than an external magnetic field, terahertz radiation can push computers into a new era. With the memory so fast, supercomputers could operate much faster; PCs could push the graphics boundaries. But the most interesting potential use of T-rays is in the fields of Quantum computers and Artificial Intelligence.

Quantum computers are, in theory, infinitely faster than silicon-based computers we use today. But, they have to rely on a classic computer memory where an external magnetic field is used for cell-resets, limiting their potential. With terahertz radiation, quantum computers could be used for solving problems even supercomputers can’t achieve. Now we only have to find someone who can find a way to program quantum computers.

T-rays used in AI research can make the process of deep learning to become immensely faster since deep learning also suffers from computer memory limits we have today. If using T-rays, AI research could finally enter a new era, where making an actual self-aware, creative and thinking AI is possible. But, years must pass before the technology becomes ready for mass production.

Researchers didn’t use T-rays on actual memory cells. For the research, they used terahertz radiation on  thulium orthoferrite, which is a weak ferromagnet. For T-rays to become usable with computer memory, more research has to be made. But the study showed positive results, meaning that we can expect T-rays to be used in a computer memory in following years.
