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.
Researchers from KAUST, University of St. Andrews, and the Center for Unconventional Processes of Sciences have developed an uncrackable security system using optical chips. The system uses silicon chips with complex structures that are irreversibly changed to send information, achieving "perfect secrecy" through a one-time key. This method leverages classical physics and the second law of thermodynamics to ensure that keys are never stored, communicated, or recreated, making interception impossible. Why it matters: This breakthrough has the potential to revolutionize communications privacy globally, offering an unbreakable method for securing confidential data on public channels.
TII and Space42 are partnering to develop the UAE’s first space-to-ground quantum communication network, integrating satellite and ground-based systems using Quantum Key Distribution (QKD) technology. The collaboration aims to develop, test, and deploy a space-based QKD solution, validating secure quantum communication links via satellite. The agreement, signed at the Dubai Airshow, covers R&D, payload development, satellite integration, and ground infrastructure. Why it matters: This initiative strengthens the UAE's cyber resilience and positions it as a leader in secure communication technologies and quantum-secure space systems.
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.
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.
This article summarizes presentations from an internal Quantum Research Center (QRC) workshop at the Technology Innovation Institute (TII). Topics covered included superconducting quantum computers, quantum coherent networks, quantum simulation, and quantum machine learning. Several presentations also discussed experimental quantum technologies. Why it matters: The workshop highlights TII's ongoing research activities in quantum computing and related technologies, signaling its commitment to advancing the field in the UAE.
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.
