Abstract: An electromechanical amplifying method including a transducing an electrical signal to a mechanical resonator having a mechanical resonance mode with an angular frequency ?0; transducing the non-linear oscillations of the resonator into a transduced electrical signal; and filtering the transduced electrical signal to obtain an output signal, the signal transduced to the resonator being obtained by adding a first input signal of a first amplitude and a first angular frequency ?s and a second pump signal of a second amplitude greater than the first amplitude and of a second angular frequency ?s that is different from the first angular frequency, the first and second angular frequencies being close to the angular frequency ?0 of the mechanical resonator and the second pump signal being chosen from a range of angular frequencies ?p and amplitudes in which the resonator is actuated in a non-linear regime.

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.
