As a viable alternative, quantum communication uses the laws of quantum mechanics to provide inherently secure communication.

zerothird is a pioneer in quantum cryptography, using entangled photons for unparalleled security and data rates. The innovation includes optimized key generation to meet the need for high data rate secret keys and the use of superconducting photodetectors for higher accuracy and speed.

With the development of quantum computers, conventional encryption methods, long based on the practical difficulty of prime factorization, will soon become obsolete. In the midst of this paradigm shift, quantum key distribution (QKD) is the logical next step in development by leveraging the principles of quantum mechanics to enable inherently secure communications. Therefore, quantum cryptography finds application in industries that require highly secure data protection, such as financial institutions, government agencies, and research institutions.

zerothird develops innovative solutions for quantum cryptography that use entangled photons to achieve unparalleled security and data rates. The technological innovation includes optimized key generation and is based on the quantum key distribution of the BBM92 protocol. The company has developed a photon source for entangled photons and optimized key generation to meet the need for secret keys at high data rates. High timing accuracy and speed are achieved by using superconducting photodetectors that can multiplex photons.
