<p>The device for reinitializing to a state |0> a quantum bit device, or Qubit as it is otherwise known, having two states |0> and |1> associated with respective energy levels E<SUB>0 </SUB>and E<SUB>1 </SUB>where E<SUB>0</SUB><E<SUB>1 </SUB>comprises first means ( 31, 32 ) for generating a temporary increase in the probability of the quantum bit device relaxing from the state |1> to the state |0> and second means ( 21 ) for absorbing the transition energy DeltaE<SUB>01</SUB>=E<SUB>1</SUB>-E<SUB>0 </SUB>ceded by the quantum bit device when it relaxes from the state |1> to the state |0>. The device is applicable to Qubits having different physical media.</p> |
