Abstract: A quantum simulator includes a chamber, a light beam generation apparatus, and a photodetector. The light beam generation apparatus includes a light source, a spatial light modulator, and a lens. Each of pixels of the spatial light modulator has a rectangular shape with a side parallel to a first direction or a second direction, and the pixels are arranged at regular intervals along the first direction and the second direction. When an xy coordinate system including an x axis parallel to the first direction and a y axis parallel to the second direction is set on an image plane, the light beam generation apparatus forms and regularly arranges focusing spots such that a minimum value of a difference between x coordinate values and a minimum value of a difference between y coordinate values of center positions of the focusing spots are longer than a non-overlapping distance.

Abstract: A pseudo speckle pattern generation apparatus includes a light source, a beam expander, and a spatial light modulator. The spatial light modulator has an intensity modulation distribution based on a pseudo speckle pattern calculated from a pseudo random number pattern and a correlation function, receives light output from the light source and increased in beam diameter by the beam expander, spatially modulates the received light according to the modulation distribution, and outputs modulated light.

Abstract: A light control device 1 includes a light source 10, a prism 20, a spatial light modulator 30, a drive unit 31, a control unit 32, a lens 41, an aperture 42, and a lens 43. The spatial light modulator 30 is a phase modulating spatial light modulator, includes a plurality of two-dimensionally arrayed pixels, is capable of phase modulation in each of these pixels in a range of 4π or more, and presents a phase pattern to modulate the phase of light in each of the pixels. This phase pattern is produced by superimposing a blazed grating pattern for light diffraction and a phase pattern having a predetermined phase modulation distribution, and with a phase modulation range of 2π or more.

Abstract: A quantum simulator includes a pseudo speckle pattern generator, a main vacuum chamber, an atomic gas supply unit, a light beam generator, a photodetector, and an atom number detector. The pseudo speckle pattern generator generates a pseudo speckle pattern in the inside of the main vacuum chamber by light allowed to enter the inside of the main vacuum chamber through the second window. The pseudo speckle pattern generator includes a controller, a light source, a beam expander, a spatial light modulator, and a lens. The controller sets a modulation distribution of the spatial light modultor based on a two-dimensional pseudo random number pattern.

Abstract: A quantum simulator includes a chamber, a light beam generation apparatus, and a photodetector. The light beam generation apparatus includes a light source, an optical mask, a spatial light modulator, and a lens. The optical mask includes an inner region having a rectangular shape with a side parallel to a first direction or a second direction, and an outer region surrounding the inner region. When an xy coordinate system including an x axis parallel to the first direction and a y axis parallel to the second direction is set on an image plane, the light beam generation apparatus forms and regularly arranges focusing spots such that a minimum value of a difference between x coordinate values and a minimum value of a difference between y coordinate values of center positions of the focusing spots are longer than a non-overlapping distance.

Abstract: A micro object control apparatus for controlling motion of a micro object within a medium includes a light source, an optical vortex generation unit, an objective lens, an imaging unit, an analysis unit, and a movement unit. The analysis unit acquires first motion information of the micro object based on the image data in which the micro object optically trapped with the optical vortex is imaged by setting the focal position of the optical vortex to a first position, acquires second motion information of the micro object based on the image data in which the micro object optically trapped with the optical vortex is imaged by setting the focal position of the optical vortex to a second position, and evaluates a state of an optical trap of the micro object with the optical vortex by comparing the first motion information and the second motion information.
