Back to computing: How can we imagine the computational method of a quantum computer to increase today's computing power in such a way

To do this, we need to delve a little into the mysteries of quantum physics.

A quantum computer does not serially process a sequence of single numbers like today's computers (like any kind of Turing machine), but works - as said before - with quantum states of microscopically small systems. As you surely remember from your physics lessons, there are such things as  Heisenberg's uncertainty principle, the wave–particle duality or other scary concepts. The background of this is: As long as I don't ask a quantum system about its state by a measurement, it can take as state any mix of all possible states. We can then "compute" with this mix by physically influencing it, for example by rotating the atoms used for the quantum computer (something like in an MRI scanner). Only after we have performed such operations, do we perform a measurement and thus force the system to assume a certain state, a result. Sounds pretty weird, and when Richard Feynman - one of the great physicists of the 20th century - made the relevant proposal for such extremely complex physical experiments almost exactly 40 years ago, we could only dream of it.

Key Facts by Stephan Melzer, Executive Project Manager, msg

  • Quantum computing can revolutionize IT like no other technology because it enables a fundamentally new kind of computing.
  • Quantum computers will be available for industrial use in the near future.
  • If complex algorithm are used in my core processes, it makes sense to start thinking about possible use scenarios today.


It is precisely the use cases of quantum computing that we want to address in the continuation of this interview.
