Abstract: The present invention relates to a 3D holographic imaging apparatus and method for projecting multiple point light sources to one plane such that qubits can be detected at rapid rate by allowing a 3D qubit model arranged in three dimensions to be simultaneously photographed in two dimensions. For this, the present invention provides a 3D holographic imaging apparatus comprising: a fluorescent unit configured to cause each qubit composing a 3D qubit model to emit qubit fluorescent beams; a lens unit configured to change the qubit fluorescent beams to a desired route; a light modulator configured to modulate each phase of the qubit fluorescent beams for each predetermined position, and control a position of a focal point; and an imaging unit configured to image the qubit fluorescent beams modulated by the light modulator in a two-dimensional (2D) image. Therefore, according to the present invention, it is possible to greatly reduce the preparation and detection time of the 3D qubit model and increase the number of detectable qubits.

Abstract: An optically trapped atom transfer tweezer includes an optical modulator which modulates incident light and generates a first hologram; a first lens which images the first hologram on an intermediate image plane and generates a first holographic image having any potential shape; a second lens which re-images the first holographic image on an entrance pupil of a third lens; the third lens which re-images a second hologram generated by the re-imaging of the second lens on a plane where an optically trapped atom array exists; a photographing device which captures optically trapped cold atoms from a second holographic image generated on the plane where an optically trapped atom array exists; and a controller which controls the optical modulator to adjust the second holographic image on the basis of the optically trapped atom image captured by the photographing device such that the optically trapped atom array is transferred to any spatial position.
