    摘要： A method for producing an adjustable bulk acoustic wave resonator comprising a transducer stack (E1) and a tuning stack (E2). According to the invention, transducer stack (E1) includes two defined electrodes (4, 6) and piezoelectric material (2), and stack (E2) includes a layer of piezoelectric material (8) and two defined electrodes (10, 12). The method includes: a) production of the transducer stack; b) formation of an electrically insulating layer on an electrode (6) of the transducer stack; c) formation of a defined electrode (10) of the tuning stack on the electrically insulting layer such that it is aligned with the electrodes of the transducer stack; d) assembly, on the electrode (10), of a substrate of piezoelectric material; e) fracturing of the substrate of piezoelectric material; and f) formation of the other defined electrode (12) of the tuning stack, aligned with the defined electrode (10).

    摘要： A Qbit spin quantum device includes juxtaposed first and second semiconducting portions, the semiconducting portions being formed in a surface layer of a semiconductor-on-insulator type substrate and disposed on an insulating layer of the substrate, the substrate being fitted with a semiconducting support layer such that the insulating layer is arranged between the support layer and the surface layer, and several pairs of front control gates, each pair being formed respectively of first and second front control gates covering a region of the first and second semiconducting portions to form first and second quantum islands, respectively. An insulating region is provided between the first and second quantal islands to enable electrostatic coupling between the first and second quantum islands. The quantum device includes a back conductive electrode vertically aligned with a coupling insulating region and being formed of a region of metal-semiconductor material alloy arranged in the support layer.

    摘要： The device includes at least the following components: a heating resistor intended for heating a component to be regenerated; a current source; a thermistor connected to the current source and thermally coupled to the heating resistor, the thermistor, through which the current flows, having a voltage Vtemp across its terminals, which voltage reflects the temperature of the heating resistor; an error amplifier, which amplifies the difference between the voltage Vset and the voltage Vtemp and delivers a voltage Vctrl that corresponds to the amplified difference; a switch, which switches the current flowing through the heating resistor; an oscillator, which delivers a voltage Vosc formed with a modulated duty cycle, the duty cycle of the pulses of the voltage Vosc being dependent on the voltage Vctrl, the pulses controlling the opening of the switch.

    摘要： The invention relates to a method for determining a coupling between magnetometers of an array of N magnetometers, for example with optical pumping, where each magnetometer comprises a field cancellation system capable of being activated to operate the magnetometer in zero field. This method comprises a first phase (P1) during which the N magnetometers are separated into N−1 magnetometers whose field cancellation system is deactivated and a measuring magnetometer whose field cancellation system is activated. This first phase comprises: the generation (GENj), by the magnetometers, of a plurality of reference magnetic fields of known amplitudes and distinct directions, the measurement (MESi), by the measuring magnetometer, of the ambient magnetic field on a plurality of measurement axes determination (CALCij) of coupling coefficients between the measuring magnetometer and each of the N magnetometers from said measurement and said known amplitudes.
