Toshiba: Quantum cryptography communication system: Successful semiconductor chip
-With a view to expanding to factories, etc.-
Toshiba:
Toshiba has changed the quantum cryptography communication system from the conventional mounting with optical components to an optical integrated circuit.
Mounted with an optical integrated circuit:
It is said that it is the “world’s first” to implement quantum cryptography communication based on an optical integrated circuit.
Chip-based quantum cryptography communication system:
“Quantum transmission chip”
“Quantum receiving chip”
We have developed a “quantum random number generation chip”.
Succeeded in demonstrating a “chip-based quantum cryptography communication system” that implements these.
Chips with semiconductors:
Plant IoT device monitoring and
In sharing design and manufacturing data between factories
In areas such as concealment of industrial information
Expand the scope of quantum cryptography communication.
The policy is to proceed with research and development toward practical use in 2024.

Toshiba shrinks quantum key distribution technology to a semiconductor chip
– 21 October 2021 –
Toshiba develops world’s first QKD system based on quantum transmitter, receiver and random number generator chips.
– Quantum chips manufactured using standard semiconductor processes. –
Significant advance towards mass deployment of quantum communications.
Cambridge, UK,
21 Oct 2021:Toshiba Europe Ltd
today announced it has developed the world’s first chip-based quantum key distribution (QKD) system.
This advance
will enable the mass manufacture of quantum security technology, bringing its application to a much wider range of scenarios including to Internet of Things (IoT) solutions.
QKD
addresses the demand for cryptography which will remain secure from attack by the supercomputers of tomorrow.In particular,
a large-scale quantum computer
will be able to efficiently solve the difficult mathematical problems that are the basis of the public key cryptography widely used today for secure communications and e-commerce.In contrast,
the protocols used for quantum cryptography can be proven secure from first principles and will not be vulnerable to attack by a quantum computer, or indeed any computer in the future.
