Plug&Play Single Photon Sources
g2-Zero is developing quantum light emitting devices and other photonic components based on semiconductors for applications in quantum communications, computing and sensing.
Our goal is to make these devices accessible and cost-effective through an innovative approach to industrialisation which will accelerate the adoption of quantum technologies across different industries.
Quantum communication technologies like Quantum Key Distribution (QKD) are set to mitigate the quantum threat by providing information security solutions that are provably secure by the laws of physics. QKD is just one use case, which, just like photonic quantum computing and quantum sensors, relies on single photons and, therefore, on single-photon sources.
In the quantum era, there will be a large demand for units of such single-photon sources. On the one hand, a global deployment of quantum networks could require of hundreds of thousands of nodes requiring several sources at each node for redundancy and multichannel communication. Meanwhile, in the case of photonic quantum computing, it is estimated that 12,000 single-photon sources will be needed to realise just one useful photonic quantum computer.
