China presents two Q-computers that would surpass the performance achieved so far by US competitors

The production of quantum computers is an increasingly frequent reality in the most advanced countries of the world. It marks the beginning of yet another transition of our time, guided by the transformation of a theoretical idea into a concrete technology.
Quantum supremacy is the real driving force of this process and the data linked to it, to say the least, amazing, are pushing research in this area to improve almost daily the results previously achieved.
As if they were modern followers of a new-born futurist movement, magnetically attracted by the concept of speed, the United States and China are the countries that are achieving the best results globally.
This time it is the Asian country that attracts the attention of enthusiasts, with the presentation of two quantum computers that would surpass (the conditional is a must when it comes to China) the performance so far achieved by US competitors.
In a single millisecond Jiuzhang 2 promises to solve the same task for which the world’s fastest conventional computer would take 30 trillion years. Even more impressive – if not yet – is the result of Zuchongzhi 2, a 66-qubit quantum supercomputer, 10 million times faster than Google’s 55-qubit Sycamore quantum computer.
What should we expect about marketing these miraculous devices? As was the case with the first computers, Q-computers will remain for some time locked up in research institutes.
At the moment, in fact, they can operate only at controlled temperature and to perform hyper-specialized tasks. Experiments are underway for calculation operations in the field of genetic mutation study, hypersonic flight simulation and stock price prediction.
The rapid growth that the sector is having, together with the widening of the application spectrum, presages a crucial role of quantum computers in the design of the society of the future. The transition in progress will soon take on the contours of a technological revolution, which will become even more appreciable when the Q-computers, like the computer progenitors, will be able to become within everyone’s reach.
EASY to understand that the first task of these quantum computers is the violation of keys encrypted with brute force attacks.
It would seem the final victory of cryptanalysts against cryptographers, only the CRIPTEOS 3001 system laughs in the face of such results, 30 trillion years are only 18 zeros to remove from the immense number necessary to force CRIPTEOS 3001 with keys of 128 KILOBYTE . Even more, the REAL DIGITAL CURRENCY is protected with keys of 40 megabytes.
Keep in mind that they were made with “normal” computers, while they are scalable with keys longer than a TERABYTE. To acts of war we will respond with acts of war…
