Quantum Cryptographic Communications
Quantum cryptographic communications are technology which based on the principles of quantum mechanics and enables the reliable detection of eavesdropping by attackers. To take quantum cryptographic communications to the global scale, we have developed technologies for the efficient construction of large-scale quantum key distribution networks, along with techniques to increase key distribution speed and extend transmission distance. We are also conducting numerous demonstration trials for a wide range of applications.

Post-Quantum Cryptography
Post-quantum cryptography (PQC) is an encryption method based on mathematical problems that are considered difficult to solve, even with quantum computers. Standardized PQC schemes require larger data sizes (sets) than current cryptosystems, such as RSA, which prompted us to work on memory-efficient, high-speed implementation techniques to apply PQC to real systems, such as HDD controllers. We are also developing lightweight PQC schemes with smaller data sizes that can be implemented even on memory-constrained devices.
Cybersecurity
Critical infrastructure, factories, plants must be protected against cyberattacks. Our dedicated security technology includes a virtualized infrastructure testbed for simulating real control systems, which allows us to develop and validate cybersecurity technologies under realistic conditions.
Simulated Bifurcation Machine
We continue to develop our simulated bifurcation machine. Based on a completely new search principle derived from our unique approach to quantum computing theory, it implements an algorithm dedicated to solving combinatorial optimization problems.
The algorithm is executed at high speed on advanced parallel processors, such as field-programmable gate arrays (FPGAs) and graphic processing units (GPUs), and quickly derives high-accuracy approximate solutions (good solutions) even for complex and large-scale problems. Proof-of-concept trials in fields including finance and automotive systems are confirming its value.
