  • Device for reinitializing a quantum bit device having two energy states
    Patent number: 6930318
    Abstract: 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 E0 and E1 where E0<E1 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 ?E01=E1?E0 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.
    Type: Grant
