Most interestingly, this warship may be equipped with an electromagnetic missile launch system that can increase the range of the missile. Recently, researchers used laser technology to develop a new quantum cryptosystem for the transmission of quantum information. The green laser pointer technology will be used to send sensitive information hidden in light particles.
It is understood that during quantum communication, quantum cryptography guarantees “unbreakable” security by hiding information in light particles or photons emitted by lasers. In the form of cryptography, quantum mechanics is used to randomly generate a key. The sender sends the key through polarized photons with different polarization directions.
The recipient uses a photon detector to measure the polarization direction of the photon, and the detector then converts the photon into bit information. If an attacker tries to intercept quantum communication messages, the cryptography will change itself due to the nature of quantum mechanics. Green Laser Pointer researchers have developed a new quantum cryptographic protocol called measurement device-independent quantum key distribution.
