New quantum states for improved quantum memories

Conventional memories used in today’s computers only differentiate between the bit values 0 and 1. In quantum physics, however, arbitrary superpositions of these two states are possible. Most of the ideas for new quantum technology devices rely on this “Superposition Principle”. One of the main challenges in using such states is that they are usually short-lived. Information can only be read reliably out of quantum memories for a short period of time. After that it is irrecoverable.

A research team at TU Wien has now taken an important step forward in the development of new quantum storage concepts. In cooperation with the Japanese telecommunication giant NTT, the Viennese researchers lead by Johannes Majer are working on quantum memories based on nitrogen atoms and microwaves. By specifically manipulating a small portion of the atoms, one can bring the remaining atoms into a new quantum state, with a lifetime enhancement of more than a factor of ten. These results have now been published in the scientific journal "Nature Photonics".

How Austria Shapes Its Future with AI

Artificial intelligence (AI) is certainly the most powerful new technology available today. This is probably the reason why the underlying discussion is frequently driven by fear. Hollywood has also contributed to this. Half-human, half-machine mutants resembling Frankenstein and Terminator are the spectres unleased by AI. However, as is often the case, Hollywood’s fantasy has little to do with reality.
