SEMINAR: Reliable Quantum Links and Networks: Purification, Error Correction, and the 1Q Architecture

JAEMIN KIM
Aalborg University, Denmark

How should entanglement be distributed when links may be wireless, there are many users, and the available resources are imperfect? I will present recent activities of the CLASSIQUE center at Aalborg University at the intersection of quantum information and communication systems. Starting from the 1Q architecture — a first-generation wireless architecture integrating classical and quantum communication — I will explain how this setting raises new quantum-information questions. Two examples form the core of the talk. The first is resource-adaptive teleportation, where a family of codes punctured from a single mother code adapts to heterogeneous per-user link quality and to the channel asymmetry induced by entanglement purification. The second is the carrier-assisted entanglement purification protocol (CAEPP), which replaces the consumption of entangled check pairs by the transmission of carrier qubits and, with multiple carriers, achieves asymptotically perfect purification under any non-entanglement-breaking Pauli channel. I will close with ongoing and planned directions as possible topics for future discussion and collaboration.
