The era of quantum computers has arrived. But what exactly are they? What effects will they have on society?

In this article you will come to know everything about quantum computers.

This year brings with it many innovations: among these, among the most important is the revolution that seems to take root in the computer world, to give rise to completely innovative and surprising changes in the development of computers.

One of the fundamental cornerstones of information technology progress is the so-called Moore law , according to which every 18/24 months the processors reduce their price and size and double the processing power.

This forecast, formulated around the ’60s, has remained an undisputed mainstay in recent decades, until we have witnessed a different and counter current phenomenon, which has made quantum mechanics a starting point to give rise to electronic devices characterized from a calculation power that makes ephemeral computers used until now ephemeral and worthless. These are the so-called quantum computers.

How quantum computers are faster compared to traditional computers?

The substantial difference compared to traditional computers is due to a profound change that undermines the very foundations of computer science: if the units of information are usually coded in the form of a binary code with the two digits 0 or 1, in quantum computers the bit has been replaced by the qubit , which can be 0 or 1, but also 0 and 1 at the same time, due to the phenomenon of quantum superposition.

Thanks to the use of qubits, in theory the computing power would tend to grow considerably, giving the possibility to carry out operations that are more complex than those possible up to now.

Quantum computers, the future also for space travel

However, the application of these techniques is extremely difficult and complex, so the actual developments of quantum computers that could lead to a real revolution still seem far away.

The maximum point of arrival would be the possibility of using these technologies to study the principles of quantum mechanics on which disciplines such as chemistry, biology and electronics are based.

At the same time, quantum computers should be the core of the development and explosion of artificial intelligence that could benefit from numerous improvements, thanks to the fact that, having to analyze very large amounts of data, quantum computers should be characterized by a more developed that previously.

If this revolution may seem cheap, just think of the actual uses that it could have in modern society, going to lead to areas such as medicine, the production of clean energy and a series of other topics that would allow an improvement in life.

Security Challenges

However, every radical revolution brings with it benefits and, at the same time, fears and problems to be solved. Even in this casemany express perplexities towards this deep development of artificial intelligence and it is feared that the development of “intelligent” machines could cause incredible damage to humanity.

On the other hand, in more applicative contexts, one of the risks that could cause the birth of quantum computers regards IT security. 

In fact, quantum computers would make the encryption algorithms currently in use completely useless, as they would be able to solve all the underlying mathematical problems.

The only solution, in this case, involves a development of the cyber security sector with the birth of new cryptography tools more appropriate for the new IT era we are facing.
