How Does Quantum Key Distribution Work?

Quantum Key Distribution (QKD) harnesses the remarkable properties of quantum mechanics to create an unbreakable encryption key for secure information exchange. It relies on two fundamental concepts: superposition and entanglement.

Superposition allows quantum particles to exist in multiple states simultaneously. In the context of QKD, this means that a quantum particle can be in a state of both 0 and 1 at the same time. By manipulating these superposed particles, two parties can generate a unique encryption key.

Entanglement is another critical concept that QKD utilizes. It involves connecting two particles in such a way that their quantum states become intrinsically linked, regardless of the distance between them. This entanglement enables the secure exchange of information between the two parties.

QKD works by exploiting the properties of superposition and entanglement to generate an encryption key that is impossible to hack or steal. This provides a higher level of security compared to traditional encryption methods. As quantum particles are extremely sensitive to any observation or measurement, any attempt to eavesdrop on QKD communication will disrupt the entanglement, alerting the parties involved.
