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.

STMicroelectronics has introduced hardware cryptographic accelerators and associated software libraries for general-purpose and secure microcontrollers, ready for future generations of embedded systems to resist quantum attacks.
