Value proposition

Enables scalable, modular quantum computing by providing the first industrialised quantum networking infrastructure that creates high-fidelity entanglement between distributed quantum processors, unlocking datacentre-scale quantum computing power

Products and solutions

["Quantum Networking Unit (QNU) - 19-inch rack-mountable platform with dynamic entangler and real-time quantum network orchestrator","Qubit-Photon Interface (QPI) - quantum analogue of classical Network Interface Card for connecting qubits to photonic networks","Entanglement Fabric - modular networking layer that interconnects quantum processors into distributed quantum computers"]

Unique value

World-first industrialised quantum networking platform with sub-microsecond reconfigurable entanglement, 99.7% fidelity, and MHz entanglement rates - moving quantum networking from academic research to practical datacentre deployment

Target customer

Quantum computing hardware developers (trapped-ion, superconducting qubits), quantum datacentre operators, cloud providers, and HPC/AI infrastructure providers seeking to scale quantum processors beyond individual device limitations

Industries served

["Quantum Computing Hardware","Quantum Networking Infrastructure","Distributed Quantum Systems","Quantum Datacentres","High-Performance Computing"]

Technology advantage

Combines photonic integrated circuits with real-time quantum network orchestration (300ns control latency) and modular architecture compatible with all qubit modalities, providing complete quantum networking stack from qubit-photon interfaces to entanglement distribution

How they differentiate

Exclusive focus on quantum networking infrastructure for distributed quantum computing with modular, photonic networking architecture that is qubit-agnostic and supports multiple quantum computer modalities
