The Quantum Tunnel Opens up New Avenues of Exploration in Wireless Communications


The world of quantum mechanics seems more nebulous than ever, defying all the standards we are used to when it comes to normal day-to-day operationses.

A particular application of quantum principles is the quantum tunnel in wireless communications - including data transfer.

I have written about other quantum applications and have been actively involved in the world of AI for years. As this field is likely to be impacted by developments in quantum computing at the quantum tunnel, I have followed the latest developments in the quantum world.

It's easy to think that breaking through insurmountable barriers is, in essence, impossible. But this is exactly where the Quantum Tunnel goes against all the odds we have believed in for so long: This phenomenon involves particles literally crossing seemingly unbreakable energy barriers.

Of course, the tunneling paints a strong visual image of the particle piercing through the barrier. But in the quantum world and on such a small scale, the phenomenon does not follow the regular explanations that we would normally use. Instead, tunneling works as a measure of probability - while particles are compared to an oscillating wave when they encounter a barrier, they are not disturbed or stopped. Instead, the wave also continues to oscillate inside the barrier, simply tunneling the probability of discovering the particle on the other side of the wall.

With the basics of the quantum tunnel clarified, it is important to understand the implications of these larger-scale technological advancements.

Recently, scientists from three international universities - Moscow Institute of Physics and Technology (MIPT), Moscow State Pedagogical University and Manchester University - have itcreated a sensitive terahertz detector. The team equips the "quantum mechanical tunneling-based detector in graphene.

What this means is that, while we have come to believe that The most advanced wireless communication methods are driven by 5G networks, this discovery in fact allows to surpass 5G connectivity capabilities and move away from traditional semiconductors and superconductors used for communication transfer. of graphene has given rise to applications "in wireless communications, security systems, radio astronomy and medical diagnostics.

Traditionally, information is carried over wireless networks via airwaves high frequency electromagnetic and in the form of discretely sequenced bits - a technique otherwise identified as signal modulation. In order to increase the bit transfer rate, it is necessary to modify themodulating frequency and increasing the carrier frequency. To better understand how different types of information are transmitted wirelessly, here are some examples of frequencies at which communication occurs:

• FM radio typically transmits at a frequency of 100 megahertz.

• Wi-Fi receivers generally transmit at a frequency of around five gigahertz.

• 5G mobile networks can generally transmit up to 20 gigahertz signals.

The higher the carrier frequency, the more data it is possible to transmit - but exceeding 100 g igahertz in frequency for a transfer is a real challenge facing us today. The reason for this inefficiency is that the system in place for sending and receiving information is obsolete - in fact, it has been in use since the era of radio and television.

The widely used elements of this process consist of amplifiers and dTransistor emodulators, which amplify weak signals while correcting signal bit sequences. This system is unsuitable in the age of mobile technology as the primary medium of communication when the transfer of hundreds of gigahertz in frequencies is required. The systems just aren't fast and powerful enough.

This is where the quantum tunnel comes in.

The new solution introduced the possibility to completely eliminate amplification and modulation in separate steps in the transmission process. Instead, the new system uses a transistor - or tunnel transistor - with the sole mission of transforming a modulated signal into a sequence of bits.

The high sensitivity of the tunnel transistor very quickly and efficiently identifies a terahertz signal. In other words, whatever the frequency, this new transistor is intended to easily pick up the signal thanks to its levelsto high sensitivity. This new type of transistor is constructed with two layers of graphene - a material in which the position of the energy levels is easily done thanks to the electric voltage.

While this is just the start of a breakthrough, I think it already foreshadows a lot of changes in the telecommunications and wireless communications industry.

New possibilities for rapid transmission of large amounts of data have the capacity to impact businesses and enterprises on a large scale.

With higher transfer capacities, businesses will be able to streamline their internal and external operations almost instantly, increasing the speed of data transfer and maximizing the efficiency of daily life.

As more businesses go digital and increase the amounts of data they have in storage, it will become possible to store, analyze andto leverage these information repositories in seconds. Transmitting them remotely will also happen in seconds.

It will also be possible to expand the network of internal devices and thus increase the overall power of the technical infrastructure as the backbone of a business enterprise. digital first. In an increasingly remote world, organizations operating on a global and dispersed scale will potentially maximize productivity through more efficient internal connectivity between employees and devices dispersed over great distances.

In other words, while the quantum tunnel is still in the development and research stage for telecommunications, it indicates a bigger change to come in the not-so-distant future - and that the future is faster, more efficient and not always in line with our notions of how communications work.ent on a regular basis.
