Quantum Cryptography:
Quantum cryptography is a type of cryptography that uses the principles of quantum mechanics to secure communication. It is considered to be unbreakable by any known current or future computer, making it the most secure form of cryptography available.
Quantum cryptography works by exploiting the properties of quantum entanglement, which is a phenomenon where two or more particles are linked together in such a way that they share the same fate, even when they are separated by a large distance. In quantum cryptography, two parties, Alice and Bob, use a pair of entangled photons to establish a secret key. This key can then be used to encrypt and decrypt messages, ensuring that only Alice and Bob can read them.
There are a number of different quantum cryptography protocols, but they all work on the same basic principle. Alice and Bob first generate a pair of entangled photons. They then send one photon to each other over a quantum channel, such as a fiber optic cable. Once they have received the photons, Alice and Bob measure their respective photons in different bases. This results in each photon having a random value, which is known as a bit.
Alice and Bob then compare their bits over a public channel. Any bits that are the same represent the secret key. Any bits that are different are discarded. Once Alice and Bob have established the secret key, they can use it to encrypt and decrypt messages.
Quantum cryptography is still in its early stages of development, but it has the potential to revolutionize the way we communicate. It is already being used in a number of commercial and government applications, and it is expected to become more widely used in the coming years.

3D Holography:
3D holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating real three-dimensional images, but also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave.
A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, generating an interference pattern which is recorded on a physical medium. The recorded interference pattern is the hologram.
When the hologram is illuminated by a coherent light source, such as a laser, the interference pattern diffracts the light, reconstructing the original wavefront. This reconstructed wavefront creates a three-dimensional image of the original object.
3D holography has a number of potential applications, including:
- Display technology: 3D holography could be used to create next-generation display technology, such as holographic TVs and smartphones.
- Medical imaging: 3D holography could be used to create more detailed and accurate medical images.
