Communications Physics journal has a focus collection on space quantum communications. The collection covers supporting technologies, new quantum protocols, inter-satellite QKD, constellations of satellites, and quantum inspired technologies and protocols for space based communication. Contributions are welcome from October 20, 2020 to April 30, 2021, and accepted papers are published on a rolling basis. Why it matters: Space-based quantum communication is a critical area for developing secure, global quantum networks, and this collection could highlight relevant research for the GCC region as it invests in advanced technologies.
Researchers at the Quantum Research Center's (QRC) Quantum Communications lab (QComms) achieved a milestone by demonstrating the violation of a Bell inequality using pairs of polarized entangled photons. This achievement serves as a "quantum health check" for their entangled photon source. The QRC team is working to harness entanglement effects in ultra-secure key distribution schemes to enhance secure communication. Why it matters: This advancement validates the application-readiness of QRC's quantum communication devices, paving the way for enhanced security in communication technologies within the region.
Dr. Najwa Aaraj from MBZUAI and TII discussed the impact of quantum computers and machine learning on cryptographic algorithms. The talk covered post-quantum cryptographic (PQC) schemes, standardization efforts, and the role of machine learning in advancing cybersecurity solutions. Dr. Aaraj also highlighted the challenges of transitioning current cryptographic systems to quantum-resistant alternatives. Why it matters: As quantum computing advances, understanding and implementing post-quantum cryptography is crucial for maintaining secure communications and data protection in the UAE and globally.
Prof. Simon Gröblacher from Delft University of Technology presented a seminar on using mechanical systems in quantum information processing, focusing on their potential as quantum memories and transducers. The seminar highlighted experiments demonstrating non-classical behavior of mechanical motion by coupling a micro-fabricated acoustic resonator to single optical photons. Quantum control over acoustic motion was established, including the generation and readout of single phononic excitations, along with light-matter entanglement. Why it matters: This research advances the use of micro-fabricated acoustic resonators for quantum information processing and fundamental tests of quantum physics.
The Technology Innovation Institute (TII) has launched the Abu Dhabi Quantum Optical Ground Station (ADQOGS), the first and largest facility in the Arab world and MENA dedicated to secure free-space optical communications. Located at Al Sadeem Observatory, the 2,363 sqm facility features an 800mm tracking telescope, control room, and weather station. ADQOGS will integrate the UAE into the global Quantum Key Distribution (QKD) network and enable ultra-secure key material availability. Why it matters: This establishes the UAE as a regional hub for quantum communication research and positions it at the forefront of developing next-generation secure networking infrastructure.
TII and Honeywell are partnering to develop quantum-secure satellite communication systems. Honeywell's ‘QKDSat’ platform will integrate with TII’s Abu Dhabi Quantum Optical Ground Station (ADQOGS) to test QKD links between satellites and terrestrial networks. The collaboration aims to build quantum-resilient communication infrastructure for government, security, and commercial use. Why it matters: This initiative positions Abu Dhabi as a key player in advancing global cybersecurity and quantum communication technologies.
TII and the UAE Space Agency announced a partnership at GITEX 2024 to build quantum communication infrastructure using UAE-built Quantum Key Distribution (QKD) technologies. The initiative includes deploying fiber-based and space-based quantum networks, utilizing TII's Abu Dhabi Quantum Optical Ground Station (ADQOGS). This partnership aims to strengthen national security and positions the UAE as a leader in unhackable quantum communication technology. Why it matters: The development of quantum communication infrastructure enhances the UAE's cybersecurity capabilities and supports its ambition to become a global hub for advanced space technology and innovation.
