When a local utility provider needed the next level of network security, quantum scientists delivered.

Researchers at DTU have successfully distributed a quantum-secure key using a method called Continuous Variable Quantum Key Distribution (CV QKD). The researchers have managed to make the method work over a record 100 km distance—the longest distance ever achieved using the CV QKD method. The advantage of the method is that it can be applied to the existing Internet infrastructure.

QuTech and Eurofiber, together with QuTech spin-out Q*Bird and other partners, have installed a proof-of-concept quantum communication system between locations in the Utrecht area. The testbed shows that it is possible to build secure communication using carrier grade dark fiber connections, integrating conventional network equipment in a quantum encryption environment.

Toshiba will demonstrate its quantum secure communication platform with Ciena (NYSE:CIEN), a global leader in networking systems, services, and software, at OFC Conference 2024. The quantum secure link will connect the Ciena and Toshiba exhibition booths with the OFCnet by using both QKD trusted node and multiplexing technology that will help to secure the network traffic over existing fiber optic cables.

Antaris, the leading software platform for space missions, today announced that it is partnering with SpeQtral to create, deliver, and deploy quantum-safe key distribution satellites for government and commercial operators. The partnership will involve integrating SpeQtral’s quantum payloads with Antaris SatOSTM space vehicle software and partner bus platforms. Antaris expects to deliver the first customer spacecraft to orbit from as early as 2026.

SK Telecom has teamed up with Nokia and five other partners to form the Quantum Alliance, which aims to develop a quantum technology ecosystem in South Korea initially, and then look abroad for international opportunities.

The Technology Innovation Institute (TII), a leading global scientific research center and the applied research pillar of Abu Dhabi’s Advanced Technology Research Council (ATRC), today announced the opening of the Abu Dhabi Quantum Optical Ground Station (ADQOGS). The state-of-the-art facility, the first in the Arab world and largest in the MENA region is dedicated to developing secure free-space optical communications.

SpeQtral, a leader in quantum communications technology, announces the launch of TarQis, a Mobile Quantum-Optical Ground Station (Q-OGS) designed to lower the barriers for access to secure communication through satellite Quantum Key Distribution (QKD). TarQis will work seamlessly with SpeQtral’s upcoming quantum satellites, allowing users to quickly familiarise and test satellite QKD technology, prove out use cases and prepare for deploying and integrating QKD solutions into their institutions.

SpeQtral, a leading quantum communications company, proudly announces the appointment of four prominent experts to its Advisory Board. Prof. Artur Ekert, Mr. Carl Ward, Prof. Carlos Cid, and Mr. John Prisco, each experts in their respective fields of quantum cryptography, cybersecurity, and business transformation, will collectively steer SpeQtral's strategic vision, enhancing its position as a global leader in quantum security solutions.

An international team of researchers from Leibniz University Hannover (Germany) and the University of Strathclyde in Glasgow (United Kingdom) has disproved a previously held assumption about the impact of multiphoton components in interference effects of thermal fields (e.g., sunlight) and parametric single photons (generated in non-linear crystals).
