Physicists have demonstrated that using two quantum channels in different orders can enhance a communication network's ability to transmit information—even, counterintuitively, when the channels are identical. This result ...
For the first time, physicists have experimentally demonstrated a quantum secure direct communication (QSDC) protocol combined with quantum memory, which is essential for storing and controlling the transfer of information. ...
(Phys.org) —In a new study, physicists have teleported photonic qubits made of pairs of entangled photons that are generated by an LED containing an embedded quantum dot. The novel set-up has advantages compared to the ...
(Phys.org)—Quantum techniques have been demonstrated to offer improvements in areas such as computing, cryptography, and information processing, among others. But in a new study, researchers from IBM have proven that no ...
(PhysOrg.com) -- When most people think of quantum communication, they think in terms of private communication channels - the ability to send messages without a third-party deciphering them. Indeed, quantum cryptography represents ...
Teleportation may be a concept usually reserved for science fiction, but researchers have demonstrated that it can be used to avoid loss in communication channels on the quantum level.

(Phys.org)—In the non-intuitive quantum domain, the phenomenon of counterfactuality is defined as the transfer of a quantum state from one site to another without any quantum or classical particle transmitted between them. ...
(Phys.org)—A team of engineers at Purdue University has succeeded in building a time cloak based on dual laser broadcast communications channels sent through a common medium. In their paper published in the journal Optica, ...
(AP) -- It might seem counterintuitive to look for higher education alongside Avril Lavigne music videos, but the video-sharing site has become a major reservoir of college content.
