Quantum Key Distribution

LuxQuanta's Quantum Key Distribution (QKD) system, marketed as NOVA LQ, provides quantum cryptography-based secure communications for telecommunications and government sectors. The system exploits quantum mechanical properties to generate shared encryption keys between two remote network nodes using optical fiber or free space transmission. The technology distributes quantum signals in the form of extremely weak light pulses combined with high-speed data processing. This approach enables detection of eavesdropping attempts on communication links, as any interception of quantum signals alters their state and reveals the presence of an intruder. QKD addresses the vulnerability of traditional cryptographic methods to quantum computer attacks. Current encryption relies on mathematical algorithms that would take conventional computers too long to break, but quantum computers are expected to crack these within the next decade. The system protects against "harvest now and decrypt later" attacks where encrypted data is stored today for future decryption. The solution targets telecommunication network providers required to protect personal data under European law, and governmental institutions handling confidential data affecting national security, economy, and public safety. The quantum-based key generation provides long-term data protection that remains secure even against future quantum computing capabilities.
