In this paper, we demonstrate, in the context of Loop Quantum Gravity, the Quantum Holographic Principle, according to which the area of the boundary surface enclosing a region of space encodes a qubit per Planck unit. To this aim, we introduce fermion fields in the bulk, whose boundary surface is the two-dimensional sphere. The doubling of the fermionic degrees of freedom and the use of the Bogolyubov transformations lead to pairs of the spin network’s edges piercing the boundary surface with double punctures, giving rise to pixels of area encoding a qubit. The proof is also valid in the case of a fuzzy sphere.

A team of physicists claims to have pulled energy out of a vacuum, Quanta reports — a trick that required them to teleport it from a different location using quantum tech.

The work builds on previous research by Tohoku University theoretical physicist Masahiro Hotta, who back in 2008 claimed to have found a way to produce negative energy, a seemingly counterintuitive aspect of quantum theory, inside a quantum vacuum.

In simple terms, instead of extracting something from nothing, the energy was “borrowed” from somewhere else, taking advantage of the idea of quantum entanglement, the fact that two subatomic particles can change their state in line with the other, even when the two are separated by a distance.

It can boost conductivity by a billion percent.

A collaboration of physicists working at different institutes in the U.S. have discovered a new quantum state in an alloy made of magnesium, silicon, and tellurium, a press release said. The finding could result in applications in quantum computing, such as building sensors and communication systems.

Electrons can move around freely inside the structure.

“This is real physics, not science fiction”.

A group of researchers essentially pulled energy out of nothing using a quirk of quantum mechanics. Two different physics experiments proved the feat is possible when they drew energy out of an energy vacuum by teleporting energy across microscopic distances.

The new experiments drew on a 2008 theory from theoretical physicist Masahiro Hotta at Tohoku University, as per a report from Quanta Magazine.

Scientists have discovered how to reverse time inside a quantum system. From a teenager taking a stylish Delorean 88 miles per hour to two-hearted alien creatures flying a blue police box, our fiction has been filled with fun stories about time travel. However, it looks like time travel is now no longer a matter of science fiction but science fact.

Quantum mechanics requires a willingness to embrace the inherent unpredictability of the world and the crucial role of the observer. A wave function collapse serves as the interface between the quantum and phenomenal.

Scientists at Georgia Tech have discovered a new quantum state in a quirky material. In a phenomenon never before seen in anything else, the team found that applying a magnetic field increased the material’s electrical conductivity by a billion percent.

Some materials are known to change their conductivity in response to a changing magnetic field, a property called magnetoresistance. But in the new study, the material does so to an incredible degree, exhibiting colossal magnetoresistance.

The material is an alloy of manganese, silicon and tellurium, which takes the form of octagonal cells arranged in a honeycomb pattern, and stacked in sheets. Electrons move around the outside of those octagons, but when there’s no magnetic field applied they travel in random directions, causing a traffic jam. That effectively makes the material act like an insulator.

A shelved theory seems to have given new life to energy teleportation, a concept that pulls energy from one location to another. The notion might sound like science fiction, but some scientists demonstrated that it is possible to generate energy out of thin air.

According to The Space Academy, scientists were able to extract energy and filled a vacuum through two separate experiments. It has indeed opened a fresh world of quantum energy physics.

Quantum mechanics deals with the behavior of the Universe at the super-small scale: atoms and subatomic particles that operate in ways that classical physics can’t explain.

In order to explore this tension between the quantum and the classical, scientists are constantly attempting to get larger and larger objects to behave in a quantum-like way.

Back in 2021, a team succeeded with a tiny glass nanosphere that was 100 nanometers in diameter – about a thousand times smaller than the thickness of a human hair.
