World’s first commercial source of individual photons

An Australian project has developed the world’s first commercial source of individual photons using diamond based quantum technology. The device will greatly benefit the emerging quantum technology industry, including quantum computing, quantum cryptography and quantum imaging.
The Single Photon Source, which can be accessed with a standard optical fiber connection, can produce a particle of light at room temperature on demand . The system works by growing microscopic crystals of diamond directly onto the tips of optical fibers, allowing the single photons emitted from the diamond crystals to be channeled directly into the fiber, overcoming the issues of single photon generation in current quantum. communication systems The organization behind the development, Quantum Communications Victoria (QCV), is considering commercial
partners and investors to participate in a start-up which will pursue commercialization of the Single Photon Source in various market.“The availability of a commercial single photon source will enable many viable quantum technologies to reach the market place.” “As an initial application the Single Photon Source will be integrated into existing commercial Quantum
Cryptosystems, drastically improving their performance and providing one hundred percent secure telecommunications”.Further applications for the technology are expected in other quantum communications areas plus microscopy and optical sensing.Photons are one of the particles through which physicists can study quantum phenomena such as quantum entanglement and quantum superpositions. Quantum entanglement is the foundation of most quantum technology proposals, and refers to the correlation in behavior between separated particles on a sub-atomic scale. Although the objects are spatially far apart, altering the
position or spin of one instantly causes the other to compensate.
When harnessed to perform operations on data, this phenomenon does not simply speed up
processors, but opens the door for a completely new species of computer which could tackle
calculations that cannot be physically solved with our current systems. Instead of storing information in binary form on bits, quantum computing stores information on,
which can hold a one, a zero and a superposition of both. The entanglement of the qubits would
also be used to instantly communicate information.It uses quantum entanglement as a form of
communication, by having the spymasters separately manipulate two entangled particles.
Privacy is ensured by the fact that nobody can observe quantum measurements without
affecting them, therefore causing a would-be eavesdropper to reveal his presence and destroy
the message. Quantum meterology and imaging use entanglement to determine precise information about the physical parameters of an object.
