of a quantum computer that will be incomparably more powerful than any existing computers, this is not science fiction, but quite a real technological problem that has several ways of solving the physical institutedemy of sciences has assembled a prototype of a quantum computer based on ions and terbium. this technology promises not only incredible performance, but also, possibly, a relatively compact installation. this is a special vacuum chamber in which such a trap is placed with and it has casel metal and terbium, scientists managed to catch them using electromagnetic fields, we make a very complex spatial configuration of electric fields, in which, as in separate single ions are located in the cells, and they stay there for a long time. they can live there for almost a week. this is the first step. now you need to cool them there so that they shake less, there is conditionally less noise, and then with the help of laser light you can control which orbit this very electron we need is in, and this is a quantum computer, this optical table, in fact, the motherboard of the quantum computer, which is being developed by fian together with the russian quantum center, is quite compact for prototype
