QPIC1550 · Quantum photonic integrated circuits at 1550 nm

The goal of this project is to create a universal QPIC platform at 1550nm by integrating InP, Quantum Dots and InGaAs detectors on SiN PICs together for the first time. This new platform has the potential to revolutionise quantum photonics by enabling the creation of on-demand single photons and entangled photon pairs, with efficient single photon detection. Critical to this platform is its compatibility with existing optical fibre networks which makes this a cost-effective solution for quantum communication, computing, and quantum metrology applications. We demonstrate the flexibility of our QPIC platform in three different use cases: Quantum Key Distribution, Remote Quantum Computing and Quantum Clock Synchronisation experiments
