Air to ground quantum key distribution
To enable global scale quantum key distribution (QKD), satellite based systems are the most promising approach. So far, free-space QKD has already been demonstrated on communication channels with attenuation comparable to satellite downlinks, and classical laser communications with satellites and aircrafts is heavily explored. Here, combining both these challenges, we demonstrate an aircraft to...
متن کاملFree-space quantum key distribution
Quantum cryptography was introduced in the mid1980s [1] as a new method for generating the shared, secret random number sequences, or cryptographic keys, that are used in crypto-systems to provide communications security. The appeal of quantum cryptography is that its security is based on laws of Nature, in contrast to existing methods of key distribution that derive their security from the per...
متن کاملFree-Space Quantum Key Distribution
Quantum key distribution is the most advanced technology to arise from the emerging field of quantum information. In fact, a few companies (MaqiQ Technologies and id Quantique) already offer commercial quantum key distribution products. But why so much excitement over QKD when our standard techniques serve just fine? Well the thing is that our standard techniques are safe only under certain ass...
متن کاملLong distance free-space quantum key distribution
In the age of information and globalisation, secure communication as well as the protection of sensitive data against unauthorised access are of utmost importance. Quantum cryptography currently provides the only way to exchange a cryptographic key between two parties in an unconditionally secure fashion. Owing to losses and noise of today’s optical fibre and detector technology, at present qua...
متن کاملFree-space quantum key distribution by rotation-invariant twisted photons.
"Twisted photons" are photons carrying a well-defined nonzero value of orbital angular momentum (OAM). The associated optical wave exhibits a helical shape of the wavefront (hence the name) and an optical vortex at the beam axis. The OAM of light is attracting a growing interest for its potential in photonic applications ranging from particle manipulation, microscopy, and nanotechnologies to fu...
