In many, because of the way it works, it can solve complex calculations in a matter of seconds or minutes, for which a normal computer would take many years. Ever since microchips were invented for binary computers, Moore’s Law was valid, according to which microchips every two years double the number of transistors they include. But this is already coming to an end, for the reason that the transistors in a microchip already reach atomic size, which prevents the quantities and with this the calculation capacities from increasing much more. There are many applications for quantum computers, from climate calculations to astronomical simulators. Although with the massive introduction in the market, the end of passwords also comes, since no matter how complex they are, they are not a problem for a quantum computer, which hacks them in seconds.
