Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion. The technique was developed by the 1966 Nobel Prize winner Alfred Kastler in the ...
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 photonics and quantum optics, quantum sensors are often built on continuous variable systems, i.e., quantum systems characterized by continuous degrees of freedom such as position and momentum quadratures. The basic working mechanism typically relies on using optical states of light which have squeezing or two-mode entanglement.
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 ...
Supercontinuum generation from a photonic crystal optical fiber (seen as a glowing thread on the left) for gradually increasing intensity of a pump laser. On the right, the spectrum of the supercontinuum is shown after the output beam passed through a prism. The higher the pump intensity, the broader the supercontinuum.
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.
In the heavy-hole spin system architecture within the double quantum dot, these quantum gate operations achieve quantum state fidelities as high as 99%. Price Action : HOLO shares are up 68.3% at ...
It is in essence a quantum interference effect that permits the propagation of light through an otherwise opaque atomic medium. [ 1 ] Observation of EIT involves two optical fields (highly coherent light sources, such as lasers ) which are tuned to interact with three quantum states of a material.
