CV-QKD system

A complete quantum key distribution (QKD) link in two 3U rack units, ALICE Tx and BOB Rx. It runs the GG02 protocol with Gaussian-modulated coherent states at 1550 nm. The receiver performs heterodyne detection with a locally generated local oscillator (LLO), removing the attacks that target a transmitted local oscillator.

OGS Quantum Stack

Discrete-variable QKD (DV-QKD) receiver hardware for optical ground stations (OGS). The QKD demodulator (DEOM) performs the polarisation analysis of the incoming single-photon signal and delivers it on four optical outputs (Out 0–3); the control unit (DCU) drives and monitors it. Both are designed to fit the telescope and optical table already in place.

Integration and deployment

Built around your infrastructure.

Keys

Standard key delivery

A built-in Key Management System (KMS) delivers keys through ETSI GS QKD 014 and 004, relays them between nodes with ETSI GS QKD 020, accepts SDN control via ETSI GS QKD 015/018, and serves IPsec (RFC 8784), Cisco SKIP and KMIP clients, plus hybrid QKD + post-quantum keys (ETSI TS 103 744).

Management

Operated like telecom equipment

Remote monitoring and management over standard interfaces, designed for network operations centres (NOCs): channel metrics and key rates in real time, exported to Prometheus.

Form factor

Standard 19″ rack

Self-contained 3U units for data centres and network nodes, designed to run over ITU-T G.652 fibre that is already in the ground.
