Anyone who deals with quantum computers will soon find their head spinning. You will suddenly find yourself deep in the field of theoretical and atomic physics. Here is just this much: where 'traditional computers' are based on two voltage states that are either exceeded or fallen short of (the bits), a quantum computer uses the many different states that an electron can assume at molecular level (the qubits). Instead of the usual 'physical space', a quantum computer uses the 'complex space' of quantum mechanics. The computing power increases and completely new algorithms become possible. It is also clear that such computers will no longer run under Windows 10 or MacOS.

Quantum computers have not yet progressed beyond the experimental stage - up to a maximum of 1,000 qubits - even if there are occasional announcements of success, presumably to attract funding. Furthermore, quantum computers are unlikely to be suitable for commercial or private use because they generally require 'superconductivity', i.e. the loss-free transmission that only occurs near absolute zero. To put it bluntly: if you want to use a quantum computer, you first have to build your own power station. Nevertheless, quantum computers are of course extremely interesting for government and intelligence tasks: no conceivable encryption could withstand the attack of quantum-based computing power. This is what makes research in this field so interesting. We, on the other hand, assume that we will not need any knowledge of quantum mechanics for our IT service in the foreseeable future.
