“Einstein’s Ghost Materialization: Quantum Entanglement and Human Intuition Challenge”
For a century, it was a theoretical frontier, a concept so unsettling that it was qualified as “a ghostly action at a distance.” But that ghost has just acquired substance: a team of scientists has successfully recreated this phenomenon experimentally between atomic nuclei separated by nanometers, demonstrating that
When two atoms “talk” without physical connection
is one of the most perplexing phenomena in modern physics. In simple terms, it happens when two particles become entangled in such a way that any change in one is instantly reflected in the other, no matter the distance between them. To explain it, scientists often resort to an analogy: two dice thrown at the same time, one in Madrid and the other in New York, always showing the same number, as if they shared a common identity.
The researchers implanted phosphorus atoms in silicon chips and used the spin of their nuclei — a quantum property that can be understood as their “internal rotation” — to encode information. As they describe it: calm, stable, but capable of communicating with others if they are tuned to the same frequency.
From impossible theory to quantum practice
The team managed to make these atomic nuclei separated by 20 nanometers (about a thousand times less than the thickness of a human hair) entangled, sharing information instantaneously. “Each room remains silent, but now we can talk to many more people, even if they are far away,” they summarized.
This achievement not only opens the door to a new generation of quantum processors, where information would travel without wires, latency, or losses, but also challenges Einstein’s beliefs.
Einstein was right… and also wrong
rejected this possibility because it seemed to violate his theory of relativity, which prohibits any communication faster than light. However, the experiments demonstrate that there is no transmission of energy or classical information between the particles: they simply form a single quantum system.
More than a hundred years later, the “ghostly” ceased to be an insult and became an open door to the future.
