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.
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.
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.
