The quantum computer is reality. Supremacy of Google but IBM does not fit

The node of quantum coherence.
Scientists have been studying how to handle quibits for decades. To take advantage of its characteristics and therefore maintain what is called quantum coherence, very low temperatures are required, they must be isolated in particular laboratory conditions otherwise they collapse. The road traveled so far has been to use superconductors, metals capable of working at temperatures well below zero.

Both IBM and Google work on so-called Josephson junctions made up of two strips of superconductors separated by an insulator. But there are also other approaches, such as the topological quantum computing that Microsoft is betting on.

The challenge for the scientific community.
Quantum computing is a challenge for few and a few. On the ball there are the large Sino-Californian platforms and a little behind Europe that last year put a billion dollars on the plate and confirmed with the new Commissioner Ursula von der Leyen her commitment in this field. In perspective there is one to unravel a cultural and technological knot at the same time.

The computer, the transistor one, has spread also due to a hippy culture that immediately made its discoveries available to the scientific community. Quantum computing, explains a source in the scientific community, will not be the case also for a logistical and economic question.

Quantum machines cannot be transported easily and require precise environments and substantial investments. Cloud solutions will have to be studied to exploit these technologies and a programming language. It will take another nine years, experts estimate, as long as an acceleration does not come from the military industry, particularly ahead of these technologies due to the potential of cybersecurity and therefore of cyberwar. In the laboratories the quantum machines that are now publicly at 54 Qbit should be much, much more powerful.
