Study Examines The Possibility Of Aliens Using Quantum Communication To Connect With Earth, Challenging Our Current Understanding Of Technology And Physics

Researchers from the University of Edinburgh have found an intriguing hypothesis about how extraterrestrial civilizations might communicate. According to Arjun Berera and Jaime Calderón Figueroa, quantum communication could allow signals to be sent across interstellar distances without loss of information.

The study, published in Physical Review D, points out that quantum particles, such as photons, could maintain their properties over vast distances in space.

Quantum communication is already being studied on Earth as a highly secure method of data transmission. Unlike traditional communication, it uses quantum particles to encode information.

One of the challenges of this process is decoherence, where quantum states are disrupted by their environment. However, in space, where matter is extremely rare, this problem could be minimized.

Berera and Calderón Figueroa specifically analyzed X-ray photons, particles of light that, according to their calculations, could traverse the Milky Way without suffering significant decoherence.

This means that if an advanced civilization mastered this technology, it could send messages across enormous distances, potentially from one side of the galaxy to the other.

The hypothesis raises new possibilities for the search for extraterrestrial intelligence (SETI). So far, efforts have focused on capturing radio signals and other classical forms of communication.

However, the investigators suggest that one should also look for quantum signals. One possible indication would be the simultaneous occurrence of classical and quantum signals, which could indicate evidence of quantum teleportation.

The study does not claim that extraterrestrial civilizations are actually using this technology, but proposes a new path for future investigations. If an extraterrestrial civilization has already developed this type of communication, scientists on Earth may eventually detect their signals.

As research in quantum communication advances, new observations may help clarify whether we are truly alone in the universe or if someone is already trying to make contact.

Study Examines The Possibility Of Aliens Using Quantum Communication To Connect With Earth, Challenging Our Current Understanding Of Technology And Physics

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

SpaceX will dock a $843 million vehicle to the International Space Station to push a nearly 420-ton laboratory against the atmosphere and make the debris fall in a controlled manner into the ocean.

How the “solar cat” became a billion-dollar threat to the Brazilian electrical system and put ANEEL on high alert after the explosion of photovoltaic energy, clandestine frauds, and the growing risk of network collapse

While the Senate stalls the end of the 6×1 schedule, a supermarket takes the lead and delights its employees by adopting a 5×2 schedule with two days off, testing reduced wear and tear, and maintaining salaries even as the workweek is set to decrease from 44 to 40 hours.

Tax reform raises an alert in industrial engineering and puts EPC contracts, heavy infrastructure, and large projects at the center of the debate.

Scientists discover that the Moon underwent an explosion so devastating that it would take detonating 130 of Earth’s nuclear arsenals to reproduce the force that created its gigantic lunar canyons in just a few minutes.

China ‘decrees’ the end of diesel: new maritime engine of 1,953 tons and 64,500 kW runs on more than 95% methanol, uses 5G technology, and could forever change the giant 16,000-container ships
