Optical communications make use of light waves, very high frequency (100 terahertz) electromagnetic waves, for information transmission. Modern optical communications were begun in the 1960s, when lasers were invented as a coherent light source. Since then, the rapid development of photonic technologies has made possible optical communication links with a …

We see things because our eyes are sophisticated light detectors: they constantly capture the light rays bouncing off nearby objects so our brain can construct an ever-changing impression of the world around us. When our eyes see a three-dimensional image such as apple, Light reflects off the surface of the apple …

Quantum key distribution (QKD), establishes highly secure keys between distant parties by using single photons to transmit each bit of the key. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that any attempts to intercept and measure quantum transmissions, will introduce an anomalously high error rate …

The military typically operates in demanding, dynamic, semi-structured and large-scale environments. This reality makes it difficult to detect, track, recognize/classify, and response to all entities within the volume of interest, thus increasing the risk of late (or non-) response to the ones that pose actual threat. A key challenge facing …

The extraordinary promise of quantum technology—depend on quantum “entanglement,” in which the physical states of two or more objects such as atoms, photons or ions become so inextricably connected that the state of one particle can instantly influence the state of the other—no matter how far apart they are.  Entanglement links …

Cryptography is a vital part of cybersecurity. Security properties like confidentiality, integrity, authentication, non-repudiation rely on strong cryptographic mechanisms, especially in an always connected, always online world. In addition, cryptography’s applications open up new opportunities and markets: digital signatures or online transactions would not be possible without it.   Quantum …

The Arctic is currently a staggering 36 degrees warmer than normal at this time of year, according to information from the Danish Meteorological Institute. NASA report also shows that a vast region in the Arctic Ocean has gone missing and people from NASA think that the polar ice caps are …

The M-2 Bradley is an Infantry Fighting Vehicle (IFV) used to transport infantry on the battlefield and provide fire support to dismounted troops and suppress or destroy enemy fighting vehicles. The M-2 has a crew of three—commander, gunner, and driver—and carries seven fully equipped infantry soldiers. M-2 Bradley IFVs are …

Military is increasingly looking to commercial ICT devices like Smartphones and tablets and they are rapidly making their way into military operations. Mobility continues to transform how the Department of Defense (DoD) operates, connects, and supports its stakeholders – most significantly, through the use of commercial mobile solutions to provide …
