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.
