World’s First Successful Demonstration of Quantum Key Distribution Technology for Multiplexing Over 30 Tbps of High-Capacity Data and Secret Keys
World’s First Successful Demonstration of Quantum Key Distribution Technology for Multiplexing Over 30 Tbps of High-Capacity Data and Secret Keys
KDDI Research, Inc. (“KDDI Research”), and Toshiba Digital Solutions Corporation (“Toshiba Digital Solutions”) have developed a multiplexing technology for quantum key distribution (QKD) that is theoretically impossible to eavesdrop. This technology assigns secret keys to the C-band and high-volume data signals to the O-band, enabling multiplexed transmission over a single optical fiber. Furthermore, utilizing this technology, we have successfully transmitted secret keys and high-capacity data signals at 33.4 Tbps over 80 km for the first time.

A Japanese Research Team Has Discovered a New One-Dimensional Topological Insulator That Can Be Used to Construct Qubits.
Recently, a research team composed of several Japanese universities and research institutions discovered a new one-dimensional topological insulator. By preparing and observing a single helical chain composed of tellurium (Te) atoms, the team proved that the electric charges did indeed appear at the endpoints of the chains, concluding that the Te single helical chain is a one-dimensional topological insulator material.
