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 ...

Final resting place of Alexander the Great

One of the versions regarding the location of the tomb of Alexander the Great mentions that the body of the great conqueror was deposited in a golden coffin, which was sent to Memphis, Egypt, and from there to Alexandria (city founded by Alexandru), where he lost track. It was thought for a time that the sarcophagus of Alexander the Great was found in Sidon (Lebanon), because the warrior with a lion's helmet carved on one side looked very much like Alexander the Great. It was later discovered that this was, in fact, the coffin of the king of Sidon. However, the search did not stop there. In 2014, the tomb of a military commander allegedly contemporary with Alexander the Great was discovered in central Macedonia. Although some historians are convinced that these are the remains of Alexander, his place of rest is still sought.

Tomb of the Red Queen, Mexico

In 1994, archaeologists discovered a mortuary in Palenque (a Mayan city). They found here a coffin with the remains of a woman, covered in red dust. Several collections of pearls were also found inside, and a diadem had been placed around the skull. Pieces of what had once been a funeral mask were also found at the scene. According to researchers, the Red Queen was around 60 at the time of her death. This was an interesting finding, as power was usually inherited only by men. As far as was known until the date of this discovery, women were not honored to such an extent that they were buried with treasures such as those found in the Red Queen's coffin. Who was this woman and how much power was concentrated in her hands? It is unknown at this time ...
