Quantum cryptography is a method that utilizes the principles of quantum mechanics, particularly superposition and entanglement, to ensure secure data transmission by distributing cryptographic keys.
Traditional cryptographic methods are vulnerable to hacking and man-in-the-middle attacks. Quantum cryptography provides an inherently secure method for key distribution by leveraging quantum mechanics principles to detect and prevent interception.
Quantum cryptography works through the use of single photons or other quantum particles. These particles can be manipulated in such a way that any attempt to intercept the communication will alter their state, thus alerting the communicating parties to potential eavesdropping.
The manufacturing process involves creating single photons or other quantum particles, often using lasers and optical fibers. The complexity of the equipment required is high due to the precision needed in generating and manipulating quantum states.
Quantum cryptography devices are built with precise optics and electronics. They require calibration to ensure that the quantum states remain intact during transmission.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and cryogenic cooling requirements.
