Abstract
The next revolution in data processing is Quantum computing.
This talk is an entertaining “tour de force” starting with a brief introduction to the fascinating yet strange theories of quantum physics, the concepts of using these in quantum computing and the latest results on qubits in devices made out of real diamonds.
If you want to learn about the machines that decrypt your passwords in the coming years and how you can actually grow diamonds in your microwave oven (and who wouldn’t?) this talk is for you!

Quantum computing uses quantum phenomena directly such as superposition and entanglement to perform data processing. However, applying these quantum concepts to macroscopic devices such as computers is an enormous challenge for information scientists and physicists alike. What does it make so hard? Well, scientists have to find a material in which they are able to store and manipulate quantum bits (qubits). Since quantum states are very fickle and thus hard to abide the most important task is to find materials in which qubits can be stored for a sufficient long time. Surprisingly they found these properties in diamond. More specific, scientists are investigating defect centers in diamond to be used as qubits. Although quantum computing in 2014 is still in its infancy first experiments have already been carried out that give hope that these computational concepts will become reality.
This talk is an entertaining “tour de force” starting with a brief introduction to the fascinating yet strange theories of quantum physics, the concepts of using these in quantum computing and the latest results on qubits in devices made out of diamond. Moreover this presentation is given by a physicist who was working on diamond for various other applications for years - who suddenly realized that he has the material for the next IT revolution right in his lab.
If you want to learn about the machines that decrypt your passwords in the coming years and how you can actually grow diamonds in your microwave oven (and who wouldn’t?) this talk is for you!
