Electronic quantum holography (also known as quantum holographic data storage) is an information storage technology which can encode and read out data at unprecedented density storing as much as 35 bits per electron. [1]
In strong interaction physics, light front holography or light front holographic QCD is an approximate version of the theory of quantum chromodynamics (QCD) which results from mapping the gauge theory of QCD to a higher-dimensional anti-de Sitter space (AdS) inspired by the AdS/CFT correspondence [1] (gauge/gravity duality) proposed for string ...
Examples of quantum imaging are quantum ghost imaging, [3] quantum lithography, [4] imaging with undetected photons, [5] sub-shot-noise imaging, [6] [7] and quantum sensing. Quantum imaging may someday be useful for storing patterns of data in quantum computers and transmitting large amounts of highly secure encrypted information.
Normally, transmission holograms [3]: Section 4.3.1 can only be reconstructed using a laser or a quasi-monochromatic source, but a particular type of transmission hologram, known as a rainbow hologram, can be viewed with white light. In a reflection hologram, [3]: Section 4.3.2 the object and reference beams are incident on the plate from ...
Holography is a technique originally invented by Hungarian physicist Dennis Gabor (1900–1979) to improve the resolving power on electron microscopes. An object is illuminated with a coherent (usually monochromatic) light beam; the scattered light is brought to interference with a reference beam of the same source, recording the interference pattern.
Quantum optics is a branch of atomic, molecular, and optical physics and quantum chemistry dealing with how individual quanta of light, known as photons, interact with atoms and molecules. It includes the study of the particle-like properties of photons.
Schematic picture of energy levels and examples of different states. Discrete spectrum states [nb 1] (green), resonant states (blue dotted line) [1] and bound states in the continuum (red). Partially reproduced from [2] and [3] A bound state in the continuum (BIC) is an eigenstate of some particular quantum system with the following properties:
The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region – such as a light-like boundary like a gravitational horizon.
