Nature: Electronic Read-out of Quantum Bits
Quantum computers promise to reach computation speeds far
beyond that of today’s computers. As they would use quantum effects, however,
they would also be susceptible to external interferences. Information flow into
and out of the system is a critical point. Researchers from KIT with partners
from Grenoble and Strasbourg have now read out the quantum state of an atom
directly by using electrodes. In the Nature journal, it is reported about the
stable interface between classical and quantum world. (DOI:
