The Internet can be thought of as a channel of information being sent from you to everyone else connected to the Internet. If you wanted to transmit your sensitive information (such as bank account numbers or military secrets) over the Internet, then you have to ensure that only the persons you intend to read your information have access to your sensitive data. Otherwise, everyone would be able to read your information, e.g., access to your bank account details and transfer money out of your account. Therefore, one needs to encrypt any data sent over the Internet. Encryption, in this context, ensures that only the intended sender and receiver can understand any message being sent over an Internet channel.

Long-distance continuous-variable quantum key distribution by controlling excess noise (2016, methodology): “Currently, two available approaches referred to as discrete-variable QKD 3,4 and continuous-variable (CV) QKD 5,6 are employed to distribute secret keys.”
Progress in Quenching Circuits for Single Photon Avalanche Diodes (2010, neutral): “For example in laser ranging [52], OTDR (Optical Time-Domain Reflectometry) [53], laser induced fluorescence [54] and QKD (Quantum Key Distribution) [55], the signal to be detected originates from a single laser pulse.”
The security of practical quantum key distribution (2008, neutral): “Alternative presentations of this material are available in many sources, ranging from books with rather general scope (Ekert et al., 2001; Le Bellac, 2006; Lo, 1998; Scarani, 2006) to other review articles specific to the topic (Dušek, Lütkenhaus and Hendrych, 2006; Gisin, Ribordy, Tittel and…”
Time-shift attack in practical quantum cryptosystems (2005, positive): “ntroduction One of the most important practical application of quantum information is quantum key distribution (QKD), whose unconditional security is based on the fundamental law of quantum mechanics [1, 2, 3, 4, 5, 6]. In principle, any eavesdropping attempt by a third party (Eve) will unavoidably ”
Micius quantum experiments in space (2022, background): “Unlike classical bits, the quantum signal of QKD cannot be noiselessly amplified due to the implications of the quantum noncloning theorem (Wootters and Zurek, 1982), where the security of QKD is rooted (Gisin et al., 2002).”
Feasibility of satellite quantum key distribution (2009, methodology): “We focus on the techniques to get a high enough SNR (in particular in the uplink) and to implement a polarization-preserving channel...”
