(Phys.org) —A team of physicists working at Karlsruhe Institute of Technology in Germany, has developed a way to cause the magnetic moments of individual holmium atoms placed on a conductive metallic base to survive for ...
It is advantageous to implement a quantum bit (qubit) with a single nuclear spin because the nuclear spin is robust against any stray magnetic fields. This robustness can be attributed to the small magnitude of the magnetic ...
