Quantum information science (QIS) is an area of study that builds on uniquely
quantum principles such as superposition, entanglement, and squeezing to obtain
and process information in ways that cannot be achieved based on classical
principles.
Quantum key distribution (QKD) uses quantum properties to send an
encryption key between two parties. Because of the way quantum mechanics works,
QKD ensures that encryption keys cannot be intercepted by a third party without the
sending and receiving parties knowing.
