Quantum teleportation over long distances

A major breakthrough in quantum teleportation has been made by NASA scientists, who sent photons of light 25 kilometers away.

This success can be used in the transmission of secure information, including communications between Earth and spacecraft.

NASA researchers did not teleport as in Star Trek, because "the experiment is fundamentally different from the 'carrier' in the series," said Francesco Marsili, an engineer at NASA's Jet Propulsion Laboratory (JPL) and co-author. author of the study, according to the Daily Mail.

The previous record for the distance of quantum teleportation of photons through fiber optics was 6 kilometers.

"We can print the state of one system to another, even when the two are far apart. Using this effect in communications we can help build a network through which secure information can be transmitted in space so that it cannot be broken." said Marsili.

Researchers at the National Institute of Standards and Technology (NIST) in Boulder, California, have developed devices that can detect even a single photon.

"It's hard to identify a single photon, you need to make a sensitive detector. Here at JPL, in collaboration with NIST, we developed the most sensitive detector in the world," said the researcher.

New informations about the Dead Sea Scrolls

The famous Dead Sea Scrolls continue to generate riddles, decades after their discovery. A recent study concluded that at least one different technique was used to obtain one of them than the rest, an unknown technique, unheard of to this day. The parchment that attracted the attention of researchers, one of the most important in the collection, is one with an age of almost 2.000 years, which has been remarkably well preserved, despite the conditions in which it was kept and despite its size. of the largest. Found by the Bedouins in 1956, north of the Dead Sea, it was sold to an antique dealer. He did not keep it in the best conditions, but still wrapped it in cellophane and stored it in a shoe box, hidden under the floor, according to Science Alert. The "Temple Parchment", as he is known, has survived, but is currently the thinnest of the parchments (a collection of about 900 pieces). It is only one tenth of a millimeter thick. However, it was preserved, and the material ...

Hundreds of metal spheres under pyramid in Mexico

Archaeologists have discovered hundreds of metal spheres buried under an ancient pyramid near Mexico City. Scientists have no idea what the mysterious balls were for. Jorge Zavala, an archaeologist at the National Institute of Anthropology and History in Mexico, described the discovery as "unprecedented." The spheres have been hidden for the last 1800 years in one of the most important pre-Hispanic temples in Mexico City, writes gizmodo.com. The city of Teotihuacan, just 45 kilometers from Mexico City, was once one of the largest cities in the world, with more than 100,000 inhabitants, at a time when only 200 million people lived on Earth. Its massive population makes it even more mysterious the total abandonment of the city in the year 700 of our era. The people of Teotihuacan knew very well that they would never return to the city, so before fleeing from it, they filled their much-loved temples with waste and garbage. Their level was so high that it took scientists only a f...

Oldest writing in the world

"The Danube Valley civilization is one of the oldest known civilizations in Europe. A German scientist, Harald Haarmann, claims that the oldest writing in the world appears on tablets discovered at Tartaria, in Romania. The tablets discovered in Romania are dated around 5,500 BC, and the symbols on them, according to the German linguist Harald Haarmann, belong to an ancient language, which has not yet been deciphered, according to Ancient Origins. These signs, which are called Vinca symbols, were found in several archeological sites, along the regions of the Danube Valley, they being inscribed on ceramics, figurines and other clay artifacts from that period. While some archaeologists believe that this writing represents only a series of geometric figures and symbols, others have argued that the sequence of symbols is the oldest writing ever discovered, it predates the Sumerian Mesopotamian and even the tablet Dispilio, which was dated. from the year 5,260 BC. The implications of...
