What Is Quantum Cryptography?
FAQs
Traditional cryptography depends on mathematical equations to create encryption keys, which could eventually be cracked by advanced computers. Quantum cryptography uses the fundamental principles of physics, specifically quantum mechanics, making it extremely secure and resistant to future threats.
Not yet. Right now, quantum cryptography is mostly used by governments, research labs, and large enterprises due to its high cost and infrastructure requirements. However, research is making it more accessible over time.
No, it primarily secures the transmission of data. While quantum cryptography can protect against interception, it can’t prevent other hacks, like exploiting vulnerabilities in software or human error. It’s a crucial piece of cybersecurity, but not the whole puzzle.
Quantum cryptography requires special hardware, like quantum communication channels, which are expensive and not widely available. Additionally, its range is limited, and it’s not compatible with current internet infrastructure without significant upgrades.
