Entangled Photon Transceiver Leveraging Photonic Integrated Circuit Technology

The development and scaling of a nationwide fault-tolerant quantum network is of crucial interest to both the domestic and international scientific community. To achieve large scale quantum networks, quantum teleportation, the technique in which quantum information (a.k.a. qubits) is transferred between a sender and receiver, needs to be realized in a low-cost, size, weight and power (low-CSWAP) form factor. Extending quantum teleportation technology to photonic integrated components, which significantly reduces CSWAP and increases environmental stability can allow for a scalable space-deployable quantum network. A key component to this system is the entangled photon-pair source.nbsp; Recent developments in quantum communications have successfully demonstrated quantum communications link in space by the Chinese Micius satellite for quantum studies and quantum communication. Freedom Photonics is exploring photonic integrated circuit (PIC) solutions for entangled photon sources in satellite applications.nbsp; The PICs that will be developed here will allow the low-CSWAP implementation of high-brightness quantum transmitters in LEO satellites to allow for enhanced quantum communications.nbsp;Photonic quantum communication devices currently have stringent system level requirements that are still being explored. Freedom Photonics LLC and our RI team member are partnering to combine high-performance photonic technology for entangled photon sources.
