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

An integrated excitonic Mach Zehnder modulator includes a heterostructure of material to create an exciton or optical input and output and two arms for excitons between the input and the output. An interference control electrode on one of the arms is used to control exciton or optical output. The materials are selected and arranged such that combining excitons at the output is controlled by voltage applied to the interference control electrode such that exciton matter waves are in phase and the interference is constructive when the output signal is on, and when the exciton matter waves are out of phase the interference is destructive and the output signal is off.

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.

A double-layer atomic chip gyroscope is composed of two layers of atomic chips, and a surface chip structure can generate closed and smooth annular magnetic guidance without a magnetic field zero point in the center; the bottom chip can generate graded transition magnetic traps, so that cold atomic groups are stably and efficiently loaded into the annular magnetic guide from the macroscopic magneto-optical trap, and meanwhile, the constraint of the magnetic traps in the angular direction of the annular waveguide is increased. Through time sequence cooperation of the two layers of chips, when annular magnetic guidance is loaded into a dimp trap formed by the bottom layer chip of a cold atomic group, angular constraint of the magnetic trap on the cold atomic group disappears, radial constraint of the magnetic trap is increased, extra angular momentum is provided for the cold atomic group, and the annular beam of the cold atomic group and the gyroscope effect of detecting matter waves are achieved. The two layers of chip wires are arranged in a planar structure, are easy to etch on the surface of the chip and are convenient to debug, and the system robustness is high.
