HEQA Security (formerly QuantLR), founded in Jerusalem in 2018, develops quantum key distribution (QKD) systems designed to be cost-effective enough for commercial deployment — a critical distinction from academic QKD demonstrations that cost millions. QKD uses quantum physics (single photon transmission) to distribute encryption keys that are provably secure against any computational attack, including future quantum computers. HEQA has announced partnerships with Singapore's SpeQtral for space-based QKD, enabling quantum-secured communications via satellite links.
QKD is fundamentally different from post-quantum cryptography (PQC): while PQC relies on mathematical problems believed to be hard for quantum computers, QKD's security is guaranteed by the laws of physics — any eavesdropping attempt disturbs the quantum state and is immediately detected. This makes QKD the gold standard for highest-security communications, particularly for government, military, and financial applications where 'believed to be secure' is insufficient.
Strategically, Israel's development of both QKD hardware (HEQA) and post-quantum software (other ecosystem players) provides a comprehensive quantum security offering. The space-based QKD partnership with SpeQtral addresses the fundamental range limitation of fiber-based QKD (typically ~100km), enabling quantum-secured links across continental distances. As quantum computing threatens existing encryption, nations that control QKD infrastructure gain a fundamental communications security advantage.
