Researchers have successfully demonstrated the UK's first long-distance ultra-secure transfer of data over a quantum ...

PQC alone is insufficient for highly sensitive communication exchanges; Quantum Key Distribution (QKD) must be integrated for maximum, unconditional security. Uses quantum mechanis to generate ...

Carried out using standard fiber optic infrastructure, the network uses two types of quantum key distribution (QKD) to ...

One application of quantum communications is Quantum Key Distribution (QKD), which helps guarantee the security of a communications network by virtue of the laws of physics. Most of today’s ...

Quantum metrology uses quanta — individual packets of energy — for setting the standards that define units of measurement and for other high-precision research. Quantum mechanics sets the ...

Quantum dots are crystals of a fluorescent semiconductor material with a diameter of as few as 10 to 100 atoms (2-10 nm). They are used as labels for imaging molecules because of their very narrow ...

In Madrid, a smaller nine-node network securely shares data using various Quantum Key Distribution (QKD) types. Cambridge and Toshiba achieved record key rates in 2019, while Bristol created a network ...

Researchers from the Universities of Bristol and Cambridge have successfully demonstrated the UK’s first long-distance ...

University of Toronto Engineering Ph.D. student Amita Gnanapandithan used both practical experiments and computer modeling to demonstrate the existence of "hidden" side channels in devices that ...

The network uses two types of quantum key distribution (QKD) schemes: 'unhackable' encryption keys hidden inside particles of light; and distributed entanglement: a phenomenon that causes quantum ...
