QDS (Quantum Digital Signatures)

Quantum Digital Signatures (QDS) are a secure method of verifying the authenticity and integrity of digital messages using principles of quantum physics. Unlike traditional signatures, QDS employ quantum states—unique, unforgeable information encoded in particles like photons—to ensure that a message genuinely comes from the claimed sender and hasn’t been tampered with. Due to the laws of quantum mechanics, any attempt to forge or eavesdrop on these signatures alters the quantum states, making such breaches detectable. This provides a highly secure way to authenticate communications, especially important for sensitive data in fields like finance, government, and cybersecurity.
