Toshiba Develops Mass-Producible High-Speed Optical Chip Quantum Random Number Generator and Verifies Operation in a Real-World Environment:

Toshiba has developed a high-speed optical chip quantum random number generator that is suitable for mass production and can be easily integrated into systems that utilize random numbers. The company confirmed that eight prototype devices operated continuously for over a week, demonstrating stable high-speed random number generation at 2 Gbps.
In 2021, Toshiba developed a quantum random number generator chip by integrating some of the optical components into a semiconductor chip using photonic integrated circuit technology, enabling mass production through standard semiconductor manufacturing processes^*1. In this latest advancement, the company has also integrated the photodetector^*2 onto the chip, eliminating the need for external optical input/output wiring. This further miniaturizes and reduces the weight of the device, making it easier to incorporate into a wide range of systems.
This chip is expected to be applicable to a broad array of use cases that require random numbers, including cryptography, computer simulators, lottery systems, and gaming.
Details of this achievement were published in the international journal Nature Electronics on May 15^*3. Part of this work was supported by the Innovate UK collaborative R&D project AQuRAND through the UK government’s Industrial Strategy Challenge Fund.
