QKD Toshiba: World’s First 30 Tbps Quantum Key Distribution
The First Successful Application of Quantum Key Distribution Technology in the World to Multiplex More Than 30 Tbps of Secret Keys and High-Capacity Data
A theoretically impenetrable multiplexing technology for quantum key distribution (QKD) has been developed by Toshiba Digital Solutions Corporation and KDDI Research
High-capacity data transmission is difficult, though, because data transmission creates noise that tampers with the secret keys
In the 6G era, AI and IoT will cause vast and diversified data flow across networks, requiring optical fibre communication's transmission capacity to be expanded
Cryptography based on computational difficulty protects transmitted data from cyberattacks, but quantum computers may be able to decrypt it
Nevertheless, QKD technology that uses weak light is vulnerable to noise produced by adjacent light wavelengths
Toshiba Digital Solutions and KDDI Research used QKD to study how O-band data signals influenced C-band secret keys. O-band transmission characteristics were determined to optimise bandwidth and optical power
The rapid progress of current information technology has made data security a major issue. More sensitive data is stored on remote computer servers, particularly the cloud, making secure access a big concern. Sending and receiving data over public networks requires encryption
Quantum key distribution in real use cases is gaining popularity to prepare for quantum computer problems. Toshiba quantum cryptography adds security to the emerging network society
Toshiba first studied quantum cryptography in 1999 at its Cambridge Research Laboratory. Recently, Toshiba has achieved several world firsts. Toshiba were the first to disclose 100 kilometres of fibre quantum key distribution in 2003. In 2010 and 2017, Toshiba achieved sustained key rates of 1 Mbit/second and 10 Mbit/second
Genome researchers have long worried about transferring huge genomic sequencing data securely. Hard drives have been physically relocated in security boxes, which is time- and cost-intensive
Toshiba QKD securely sends production data from your design department to the manufacturing centre or sensitive financial, personal, or medical data to offsite processing or storage
