How quantum computers will solve the problems that we do not even guess


After decades of experiments, billions of dollars investment worldwide and insecurity in success, researchers still proved that a quantum computer can work more efficiently traditional. Previously, Google published

First of all, quantum computers can make widely used encryption codes outdated, which stimulates some financial organizations and institutions to develop new type protective algorithms. In addition, the technology will help to solve the mass of business problems related to the optimization of individual organizational processes and all the company’s activities as a whole.

The potential of these devices is so huge that it will allow for few minutes to find answers to questions, unbearable for traditional calculation methods, or solve the problems that no one can even realize.

For example, how to avoid electricity losses when it passes through the power lines, how to use nitrogen in the air to create fertilizers for plants, or determine which molecules need to be connected to get new vital medications without spending time and money for years of laboratory research without Any guarantees for success.

All these problems combine their complexity and secrets of amazing interactions of the subatomic world. It is here that the fancy logic of quantum mechanics comes into play.

The fact is that in quantum mechanics the rules to which we are accustomed and can observe around, for example, as Newton described by Newton, do not work. In our world, objects are in a certain state, position and move in a particular direction. For classical calculations, this means that the main unit of information (bit) can be only 0 or 1.

The strange rules of quantum mechanics allow elementary particles, such as electrons or photons, not have a simple, specific state. That is, they can simultaneously be a wave field and matter, to have an infinite number of possible positions at each time of time, to disappear without a trace of one place and immediately appear in the other.

It is these particle features and are used in quantum transistors that are the main components of computing devices.

However, the Google team decided to go further and combine quantum mechanics with information technology. This allowed researchers to get a combination, which, according to them, instead of simply specifying up or down (0 or 1), can display each point in any direction around the sphere. Such a multitasking system can simultaneously handle much more information.

Being in confusing states, quantum bits (qubits) can interact with each other, which allows them to combine them to solve specific tasks.

At the same time, in contrast to the classic computer, which methodically lays its way to answer through two possible values, quantum chaotically rushes in search of a suitable result until it reaches the target. Therefore, in the course of this process, minor miscalculations and deviations may occur, which gradually accumulate and can lead to errors that today is one of their main problems of technology. However, scientists are already developing the methods of combating errors.

Most likely, quantum calculations will not be used in your next smartphone, but over the next ten-year, they may gradually penetrate our daily life.

The truth is that no one knows exactly how this technology changes the world. The effect may manifest itself in new engineering approaches, unexpected chemical formulas, ways to solve climate change problems or increase energy efficiency.

The researchers themselves cannot predict in which directions quantum computers will work better than traditional, since they cannot provide for all possible aspects.
