System Integration and Packaging towards an Integrated Photonic Quantum Repeater

Completed TRL 4 (started at 2, targeting 4)

Description

The objective of this proposal is to overcome significant challenges towards a deployable quantum repeater in a future quantum internet. We will demonstrate a path towards a cost-efficient quantum repeater node that integrates diamond color centers (CCs) as quantum memories with a photonic integrated circuit (PIC) in a compact cryogenic system.

Benefits

NASA has initiated several efforts towards both space- and ground-based quantum networks, including the National Space Quantum Laboratory, involvement under the INQNET program, and an upcoming effort under “Marconi 2.0”.

Our proposed work will greatly extend the entanglement distance for a ground-based quantum internet towards the metropolitan scale of 100+ km through the successful development of a quantum repeater.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
