QUANTUM CRYPTOGRAPHY
QUANTUM CRYPTOGRAPHY
Information security over a network is the focus of the quantum physics area of study known as quantum cryptography. It is founded on the fundamental ideas of quantum physics, which regulate the behavior of subatomic elements.
We will examine quantum cryptography in this blog post using instances.
- Quantum Teleportation Prank:
Consider that you and your buddy are both quantum scientists and that you have decided to pull a joke on them. You entangle two particles in secrecy, giving one to your buddy and retaining the other for yourself. After that, you instruct your buddy to measure the atom they possess and report back to you. You "teleport" a message to your buddy that shows on their computer screen using this knowledge and the entanglement. Your acquaintance will be astounded and perplexed, believing that you have just used quantum tunnelling to send them a message!
2. Quantum Cryptography Escape Room:
Consider yourself in an escape room where the hints are protected by quantum encryption. Quantum keys created by a quantum computer are used to encode the information. To obtain the quantum keys and decode the hints, you and your team must solve puzzles and respond to riddles. The caveat is that if you don't get out in time, the quantum computer will delete the keys and seal you in eternally. There is a timer that is counting down.
3. Agent of Quantum Cryptography:
Consider yourself a covert operative who needs to communicate with your partner without the adversary learning about it. You create a private key using a quantum key distribution method that you and your partner can use to encode and decrypt communications. You have to be cautious with your communications because the quantum key can only be used once. A private chat programme that makes use of quantum cryptography will let you and your companion interact. Additionally, your communications will be completely scrambled and unintelligible if the adversary manages to intercept them.
