Quantum communications harness the principles of quantum physics to enhance data security. Traditional encryption methods involve sending digital keys algorithmically, which can be intercepted by hackers, potentially compromising sensitive information. In contrast, quantum communication employs quantum bits (qubits), often using photons of light, which can exist in superposition, representing both 1 and 0 simultaneously. If a hacker attempts to observe qubits, their quantum state collapses, leaving a trace and allowing for the reissuing of new keys. Additionally, quantum random number generation generates truly random keys based on quantum unpredictability. Standardised testing methods for optical components and random number generators are crucial for ensuring the security of quantum technologies, making quantum communications a promising solution for safeguarding sensitive data.
