A: An axon terminal releases neurotransmitters through a synapse and are received by microtubules in a neuron's dendritic spine. B: Simulated microtubule tubulins switch states. [1] Hameroff proposed that microtubules were suitable candidates for quantum processing. [31] Microtubules are made up of tubulin protein subunits.
Quantum optical coherence tomography (Q-OCT) is an imaging technique that uses nonclassical (quantum) light sources to generate high-resolution images based on the Hong-Ou-Mandel effect (HOM). [1] Q-OCT is similar to conventional OCT but uses a fourth-order interferometer that incorporates two photodetectors rather than a second-order ...
The discovery of the Hanbury Brown and Twiss effect – correlation of light upon coincidence – triggered Glauber's creation [24] of uniquely quantum coherence analysis. Classical optical coherence becomes a classical limit for first-order quantum coherence; higher degree of coherence leads to many phenomena in quantum optics.
Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule. Microtubules play an important role in a number of cellular processes.
Optical manipulation techniques, such as laser cooling, can lead to long coherence times for atoms. Coherence time refers to the time during which a quantum system can maintain its quantum superposition state before decoherence occurs. Long coherence times are essential for performing quantum operations and minimizing errors in quantum ...
Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
In physics, coherence theory is the study of optical effects arising from partially coherent light and radio sources. Partially coherent sources are sources where the coherence time or coherence length are limited by bandwidth, by thermal noise, or by other effect. Many aspects of modern coherence theory are studied in quantum optics.
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.
