Our Quantum Toolbox
Quantum Photon Sources: Qunnect develops sources designed for integration into real-world, hybrid quantum networks. Our innovative design generates entangled-photons with ultra-high brightness and sub-GHz linewidths. The photon pairs are ideal for interfacing with both optical fibers and atomic devices without requiring frequency conversion.
Qubit Synchronization: Qunnect is the first company to commercialize quantum memories, which operate at room temperature and are designed to store photons with high-efficiency and fidelity. Our memories have long storage times to support qubit synchronization over long-distance networks.
Entanglement Swapping & Photon Decoding: high-stablility interferometric devices to support entanglement swapping transactions between two distant entanglement source nodes to distribute entanglement. The same devices can be used as rapid synchronized photon decoding modules.
Qubit Frequency Conversion: light-matter interface designed for situations in which a telecom frequency photon needs to be stored/buffered in a quantum memory operating at near-IR frequencies. The reverse process is also supported for sending a photon from a local quantum node into fiber networks.
Phase & Frequency Locking: Installed at every quantum instrumentation node, these devices provide frequency locking of up to eight independent lasers to atomic transitions or enable phase locking between lasers.
Flying Photon & Transport Compensation: Qunnect combines fast optoelectronics with machine learning to preserve polarization qubits, which can be damaged during transmission through real telecom fibers. The Qu-APC assures maximum network fidelity with minimal downtime.
Hybrid Network Synchronization: designed for synchronizing all devices in a large multi-node quantum network to a common clock. Our technology combines different protocols to achieve sub-ns accuracy for nodes up to 120km apart. The same device can also generate trigger signals/temporally shape laser pulses at the nodes.
Quantum memories and entanglement sources are vital innovations for large-scale quantum networks. To this day, these devices primarily work at cryogenic temperatures or require cumbersome operating infrastructure. Consequently, they have only been demonstrated in laboratory environments and never field-deployed.


In contrast, our devices permit quantum links that operate at room-temperature by leveraging atomic interactions with photons. This technical simplicity is crucial to support scalable architectures and facilitate a rapid technology rollout.
