Quantum entanglement sources are to quantum technology what lasers are to optical technology. The invention of lasers hascreated a photonics industry worth of $650 billion in 50 years, with applications cover everything from DVD players to industrialcutting and welding, from laser surgery to long-distance communication. The Internet would not have been possible without lasers.Likewise, entangled photon sources will play an equally important role in not-too-distant future. They produce photons exhibitingquantum correlations that cannot be mimicked by classical particles. The quantum correlations can be harnessed to performfunctions impossible to achieve classically, such as unconditional security in communication, efficient algorithm in quantumcomputing, and ultra-high resolution in quantum imaging.A basic quantum entanglement source produces entangled photon pairs, which are pairs of photons prepared in a specialquantum state that exhibits strong correlations. Such correlations enable many unconventional usages of the quantum resource.Entanglement-based quantum key distribution (QKD), for example, utilizes the correlation of the photons sent to two remoteparties and allows them to share a common cryptographic key and any eavesdropping attempt would result in a detectabledeterioration of correlation.The aim of this project is to develop a practical, low-cost, turn-key entangled photon source based entirely on fiber-compatiblecomponents. We will leverage Ozs expertise in photonic packaging and product development. Quantum technology will play animportant role in the 21st century. Entanglement sources are essential for many quantum applications. This proposal aims to takethe first step towards developing commercially viable entanglement sources.
