Quantum Entanglement offers unprecedented precision for GPS, Imaging and beyond

Engineers have demonstrated for the first time that it’s possible to connect a network of sensors through quantum entanglement. The experiment opens a door to unprecedented levels of sensitivity in GPS navigation, medical imaging and astronomy.

Your phone’s GPS, the WiFi in your house and communications on aircraft are all powered by radio-frequency waves, or waves, which carry information from a transmitter at one point to a sensor at another. The sensors interpret this information in different ways. For example, a GPS sensor uses the angle at which it receives an RF wave to determine its own relative location. The more precisely it can measure the angle, the more accurately it can determine location.

Exoplanet apparently Disappears in Latest Hubble Observations

This diagram simulates what astronomers, studying Hubble Space Telescope observations, taken over several years, consider evidence for the first-ever detection of the aftermath of a titanic planetary collision in another star system. The color-tinted Hubble image on the left is of a vast ring of icy debris encircling the star Fomalhaut, located 25 light-years away. The star is so brilliant that a black occulting disk is used to block out its glare so that the dust ring can be photographed. In 2008, astronomers saw what they thought was the first direct image of a planet orbiting far from the star. However, by 2014, the planet candidate faded below Hubble’s detection...

Top biomedical engineering researcher develops synthetic scaffolds for tendon and ligament regeneration. Australia’s love of sport means it has one of the highest rates of knee anterior cruciate ligament (ACL) injury and reconstruction in the world.

Worldwide, the costs of tendon and ligament rupture repair and surgery revision represent tens of billions of dollars of the clinical orthopaedic market.

A team of biomedical engineering researchers from the University of Sydney, working with Columbia University’s Regenerative Engineering Laboratory and FAU Erlangen-Nurnberg Institute of Medical Biotechnology (Germany), are hoping to improve the outcomes of tendon and ligament repair by developing a new synthe...

New discovery settles Long-Standing Debate about Photovoltaic Materials

Ames Laboratory scientists discovered evidence of the Rashba effect by using extremely strong and powerful bursts of light firing at trillions of cycles per second to switch on or synchronize a “beat” of quantum motion within a material sample; and a second burst of light to “listen” to the beats, triggering an ultrafast receiver to record images of the oscillating state of matter.

Scientists have theorized that organometallic halide perovskites— a class of light harvesting “wonder” materials for applications in solar cells and quantum electronics— are so promising due to an unseen yet highly controversial mechanism called the Rashba effect. Scientists at the U.S...
