TI  - Andreev quantum dots for spin manipulation.

AB  - We investigate the feasibility of manipulating individual spin in a 
      superconducting junction where Bogoliubov quasiparticles can be trapped in 
      discrete Andreev levels. We call this system an Andreev quantum dot (AQD) to be 
      contrasted with a common semiconductor quantum dot. We show that the AQD can be 
      brought into a spin-1/2 state. The coupling between the spin and superconducting 
      current facilitates manipulation and measurement of this state. We demonstrate 
      that one can operate two inductively coupled AQDs as a XOR gate; this enables 
      quantum computing applications.
