The quantum computer and why is it so dangerous?

After about 10 years, quantum computers will become a threat to the blockbuster technology that lies at the root of the crypto-technology. An international group of scientists has reached this conclusion. According to them, most modern cryptographic protocols that ensure the safety of Internet transactions and financial transactions are potentially vulnerable to a powerful quantum computer. Services that can be hacked are also covered by crypto looks.

Moreover, Bitcoin's mining is relatively safe, as in the near future for e-currencies it will require equipment much more powerful than quantum computers. The algorithm for creating a digital signature based on elliptical curves that are used in Bitcoin is more vulnerable. Generally, according to the authors of the study, quantum computers will become a threat to crypto-data as early as 2027 if not earlier.

"Such an attack is likely to be effective, as it takes about 9 minutes for a battlefield to take between the transaction and the blocking process. In 10 years, quantum computers will then be able to calculate the personal key on the basis of the public, which will allow, for example, to redirect the funds transferred to another portfolio, "- warn scientists.

The idea of ​​using the quantum properties of elementary particles for computational purposes is not new and dates back to the 70s of the 20th century.

For years, the subject has been a field of purely theoretical developments. At the beginning of the 21st century, however, scientists are already working intensely on building the hardware. Naturally, the most commonly asked question by non-specialists is "What is a Quantum Computer?".

Unlike electronic computing devices that use electricity, the quantum computer stores, and processes data by exploiting the quantum properties of atoms and elementary particles. The information in the traditional electronic computer is stored in the form of bits, which may have one of two possible states - 0 or 1. On the quantum computer the information is stored in "cubits" (ie quantum bits) that may not be only in state 0 or 1, but in both simultaneously (0 and 1). It is here that the quantum mechanics of quantum mechanics, which contradict common sense, begins. Strangles that bring mastiffs to sound minded scientists to the edge of madness, as well as hardened atheists - to faith in God.

What will happen and how this change will affect ... someday we will understand!
