Quantum Key Distribution, or QKD, has drawn significant attention in the space industry. By making use of cryptographic security rooted in the laws of physics, it promises to safeguard communications against future threats posed by quantum computing. This — an encryption method that is, in theory, unbreakable — is a tantalizing prospect for players in the space industry, which continues to push the boundaries of what’s possible with technology. It seems to solve the thorny problem of ensuring the security of global communications across vast distances. But my advice is…
