Photon Behaviour Harnessed

Quantum entanglement a physical phenomenon that has applications in fields like communications, computing, biology, and chemistry. It infers that the prior interaction of two quantum systems allows the prediction of the behaviour of one of these two systems by merely observing the other. This technology generates entangled pairs of light particles (photons), producing a commercial product that can be used by research institutes for further scientific research particularly in microscopy and cyber security.

Brief description of the technology’s market need.

Quantum entanglement is a fundamental physical concept with applications in communication, computing, biology, and chemistry. The concept infers that prior interaction of two quantum systems allows the prediction of the behaviour of one of these systems by merely observing the other. The technology generates entangled pairs of light particles (photons). Currently, the main market for this technology is higher education as well as any enterprise which pursues research and design (R&D). While Quantum Entanglement is a fundamental concept that is taught and investigated at a postgraduate level, it has various applications in the R&D fraternity.

Some of the applications of entanglement sources are mentioned below:
Quantum Biology: This is a relatively new field of study, with many core concepts rooted in entanglement theory. One such application is synthetic photosynthesis and light harvesting. The understanding and retrieval of light through a quantum process creates a highly efficient means of solar energy.

Quantum Computing: The use of entanglement in quantum computing is well documented. Quantum memories are of most prominence in regard to this. Entanglement provides a means to read and write into a memory allowing long-scale calculations to be computed.

Quantum communication: Again, Quantum memories play a pivotal role in the implementation of a quantum signal relay or regenerators. The use of these memories allows application of both the aforementioned giving rise to better Quality of Service for quantum networks.

Microscopy: The use of entangled photons enhances microscopes through the better illumination of the specimen. Better visibility is achieved with an entanglement photon pair light source as opposed to a conventional light source.

Quantum Chemistry: Quantum entanglement can be used to measure the electron correlation of molecular systems.

Brief description of the technology’s benefits.

OQES is designed as a high efficiency, photon-on-demand source. The innovative design uses nonlinear effects to enhance the quality of entanglement as compared to current products.

The attributes of the technology that makes it unique.

The core output is a commercial product that can be used by research institutes for further scientific research and microscopy. This technology creates entanglement of light at a wavelength of 810 nm, ideal for free space communication. Using a higher intensity laser with a post-production selection criterion, to be developed, the device will produce a better quality of entangled photons at higher data rates. The above ensures that the proposed device maintains a superior efficiency.

The main idea behind the technology is described.

This technology aims to provide a high efficiency, a photon-on-demand source for application multiple fields of study and innovation, particularly for improving the light source of microscopes.
