The invention relates to a method for controlling and implementing an atom interferometer, in which at least one ensemble of atoms is prepared in an out-coupling state, wherein the out-coupling state describes the state after cooling procedures and / or other preparation steps or generally the state before the following steps, in which the at least one ensemble of atoms is then transferred to a transfer state different from the out-coupling state by a transfer control intervention, in which the at least one ensemble of atoms is subsequently transferred to an atom interferometer input state by at least one relaunch control intervention, in which a matter-wave interferometry sequence is then carried out with the at least one ensemble of atoms by means of coherent control interventions acting on the at least one ensemble of atoms.The invention also relates to an atom interferometer configured to carry out such a method, and to a computer program for carrying out such a method.

The application discloses an atomic matter wave wavelength measuring device, which comprises a vacuum cavity. First split beam light and second split beam light obtained by splitting test laser light both pass through the vacuum cavity in a direction parallel to the height direction of the vacuum cavity, are combined, and are detected by a first photoelectric detector. The vacuum cavity is also irradiated with probe laser light. The shape of the middle light path is rectangular from the splitting of the test laser light to the combination of the first split beam light and the second split beam light to obtain combined beam light. The application also discloses an atomic matter wave wavelength measuring method. The test laser light is adjusted to be slit light to measure the actual flight time of the measured object. The test laser light is adjusted to be continuous laser light to measure the actual flight distance of the measured object, so that the actual flight speed of the measured object and the matter wave wavelength are obtained. Since the application is not affected by the initial position change of the measured object, the flight speed of the measured object can be measured, and the precise measurement of the matter wave wavelength can be realized.

To integrate a large number of propulsion force generating devices accompanied by an air current as reaction in a propulsion force direction while avoiding the air current.SOLUTION: In one embodiment of the present invention, a centrifugal force is applied to the air flow in a direction perpendicular to the direction of the propulsive force, and the path of the air flow is controlled so that the air flow does not hit other components of the stack. As a propulsive force generating device, there is a technique for obtaining a propulsive force by breaking the balance of atmospheric pressure in the device by diffraction of gas molecules derived from the wave nature of matter waves based on the quantum theory. Since this technology is in the field of fine technology including nano-technology, the device size is small, and it is necessary to integrate a large number of devices in order to obtain a practical driving force. A practical propulsion force can be obtained by the accumulation method of the present invention.SELECTED DRAWING: Figure 18

The invention relates to a method for controlling an atom interferometer, in which at least one ensemble of atoms is prepared and provided in an atom interferometer input state, and the state of this ensemble is changed to subsequent states different from the atom interferometer input state by means of coherent control interventions acting upon it, and a matter-wave interferometry sequence is performed with this ensemble. The invention further relates to an atom interferometer configured to carry out such a method, and to a computer program.

Each atom in a population of atoms can be characterized by a probability density distribution (PDD). Using a shaken-lattice technique, each PDD is split into a pair of sub-PDDs. The sub-PDDs of a pair are propagated along different paths to a common endpoint of the paths, resulting in a matter-wave interference pattern that encodes a net phase between the paths, e.g., due to differential effects associated with a gravity gradient. The matter-wave interference pattern can be measured to yield a respective measurement for each atom. The measurements can be aggregated to yield a result distribution that can serve as a classical domain estimate of the quantum-domain matter-wave interference pattern, and thus of the gravity gradient. Other embodiments can determine gradients for other types of fields.
