Quantum cryptography uses principles of quantum mechanics to create secure communication channels. It leverages the properties of particles such as photons to transmit cryptographic keys that are virtually unbreakable.
It addresses the vulnerability of traditional cryptographic systems to quantum computers which could potentially break current encryption methods.
In quantum cryptography, information is encoded in the state of quantum particles like photons. Any attempt to intercept or measure these particles will change their state, alerting both communicating parties to a potential eavesdropper. This allows for secure key distribution and encryption methods that are theoretically unbreakable.
Manufacturing involves creating precise optical devices, such as single-photon sources and detectors, often using semiconductor technologies or specialized fibers. These components must be highly stable and sensitive.
The build process includes designing and fabricating quantum devices, integrating them into secure communication networks, and testing for reliability and security.
