The QubitCore payload, launched on March 30, 2026 aboard SpaceX’s Transporter-16, is housed in a 1U CubeSat and integrates an entangled photon source, optical receivers, and time-tagging electronics.
This mission marks a shift from government-led experiments to modular, commercially developed hardware for space-based quantum communication, focusing on validating entanglement-based QKD protocols under Low Earth Orbit conditions.
Qubitrium aims to provide a standardized platform for quantum networks, with future plans including a second-generation payload featuring an optical telescope to enable secure intercontinental communication and support for quantum memories and ground stations.

Milestone in Space-Based Quantum Communication: QubitCore’s Compact QKD System Validated on SpaceX Transporter-16
Overview
On March 30, 2026, Qubitrium launched its miniaturized QubitCore payload aboard SpaceX’s Transporter-16 mission, marking a major step in commercial quantum communication. Designed as a compact 1U CubeSat with a modular quantum system, QubitCore uses radiation-hardened components and low power to operate reliably in space. After deployment, it successfully demonstrated quantum key distribution in orbit, becoming the first CubeSat-scale payload to generate secure quantum keys. This success attracted €2.25 million in funding, accelerating development of advanced payloads with optical downlink and quantum memory. Qubitrium’s modular approach aims to build a global quantum internet, supporting ultra-secure communication and European technological sovereignty.
