Problem
The Challenge: Overcoming Photon Loss
Quantum communication holds the promise of unbreakable encryption and secure data transmission. However, existing methods face significant challenges due to photon loss over long distances, hindering the establishment of a global quantum network. Conventional approaches relying on quantum memories and repeaters have proven to be complex and impractical.
Solution
Satellite-Relayed Quantum Communication
Our groundbreaking solution utilizes a chain of low-earth orbit (LEO) satellites as optical relays to transmit quantum signals across vast distances without the need for quantum memories or repeaters. By employing "satellite lenses" that focus and reflect quantum light signals, we minimize photon loss and enable efficient global-scale quantum communication.
Benefits and Applications
The ASQN offers numerous benefits and applications, including:
-
Secure Global Communication: Enables fully secure global data transmission through quantum key distribution (QKD).
-
Quantum Key Distribution (QKD): Facilitates the secure exchange of encryption keys, ensuring unbreakable security for sensitive information.
-
Distributed Quantum Computing: Supports the linking of quantum computers across the globe, enhancing computational power and capability.
-
Entanglement-based Precision Quantum Sensing: Improves the accuracy of measurements in applications like atomic clocks and very long baseline telescopes.
Entanglement Distribution
Our numerical modeling shows that using 'satellite lenses' significantly reduces diffraction loss, maintaining the integrity of the entangled photons even over distances up to 20,000 km. This high fidelity is crucial for effective QKD, where the security of the communication relies on the purity of the entanglement. By optimizing the lens setup and minimizing other forms of loss, we achieve a robust entanglement distribution process, enabling secure global communication and enhancing precision quantum sensing applications.

Qubit Transmission Protocol
The qubit transmission protocol involves sending photons from a ground-based source to a ground-based detector through a chain of satellites. This protocol includes an uplink, where photons are transmitted from the source to the first satellite, reflections between satellites, and a downlink to the final ground station.
One of the key advantages of this protocol is that both the photon source and the detector remain on the ground. This setup simplifies the system and reduces the need for complex equipment in space. However, it also introduces challenges such as atmospheric turbulence during the uplink. Our specific lens setup is designed to mitigate these challenges, focusing the fragmented beam and minimizing diffraction loss.

Efficient and Scalable Protocol
In our approach, photons are sent directly through space using a chain of co-moving low-earth orbit (LEO) satellites. These satellites bend the photons to move along the earth’s curvature and control photon loss due to diffraction, effectively behaving like a set of lenses on an optical table. Numerical modeling of photon propagation through these 'satellite lenses' shows that diffraction loss in entanglement distribution can be almost eliminated, even at global distances of 20,000 km, while considering beam truncation at each satellite and the effect of different errors, such as 'satellite lens' focal length fluctuation.
