Business Start-Up Award winner: AEGIQ

AEGIQ receives a Business Start-Up Award for the development of a breakthrough quantum photonics platform enabling new applications in quantum communications, computing, and imaging utilising high-performance sources of indistinguishable single photons. 


AEGIQ’s propriety iSPS technology is a turn-key source of true quantum light offering world-leading performance. The system architecture is based on the incorporation of an artificial atom, known as a quantum dot, in an on-chip optical resonator. Through careful engineering of the nanophotonic circuitry around the resonator the system is capable of operating at 10s of GHz speeds, delivering a train of single photon pulses to the output of an optical fibre with deterministic operation.

This simple turn-key operation of an iSPS system and world-leading single photon performance enables new avenues of applications across a wide range of R&D areas including optical quantum computing, quantum imaging, microscopy and metrology.

The pioneering performance of the iSPS technology combined with the ability to operate at telecommunication wavelengths offers huge potential for the development of quantum secure communication networks based upon deterministic source of quantum light. Here, the technology can be deployed without major infrastructure changes and in the window of minimum atmospheric losses for free-space quantum communication via satellites.

The company is actively engaged with several early adopters with a wide range of applications for their sources. AEGIQ is rapidly developing the systems around the technology with the aim of embedding their systems at the heart of the emerging global quantum networks.
