Researchers at the University of Science and Technology of China have recently introduced a new satellite-based quantum-secure time transfer (QSTT) protocol that could enable more secure communications between different satellites ...
The ability to securely transmit information over the internet is extremely important, but most of the time, eavesdroppers can still generally determine who the sender and receiver are. In some highly confidential situations, ...
(Phys.org)—The relationship between communication complexity problems, Bell nonlocal correlations and the advantage of quantum over classical strategies has long been recognized, but has been confirmed in only two problems. ...
(Phys.org)—Quantum key distribution (QKD) may one day allow for nearly perfectly secure data communication on a large scale, but before this can happen, QKD networks must extend across distances that are large enough to ...
A scientific paper published in 1985 was the first to report a burgeoning hole in Earth's stratospheric ozone over Antarctica. Scientists determined the cause to be ozone-depleting substances—long-lived artificial halogen ...

(Phys.org)—Intruders of the break-in and snooping variety have their work cut out for them by just picking up wireless signals that are broadcast by utility meters, say researchers from the University of South Carolina ...
The University of Colorado at Boulder is working with NASA to develop a new communications technology now being tested on the International Space Station, which will extend Earth's Internet into outer space and across the ...
