In 2022, the physics Nobel prize was awarded for experimental work showing that the quantum world must break some of our fundamental intuitions about how the Universe works.

Many look at those experiments and conclude that they challenge “locality” – the intuition that distant objects need a physical mediator to interact. And indeed, a mysterious connection between distant particles would be one way to explain these experimental results.

Others instead think the experiments challenge “realism” – the intuition that there’s an objective state of affairs underlying our experience. After all, the experiments are only difficult to explain if our measurements are thought to correspond to something real.

The Eqs. (3a) and (3b) suggest two important features of the location of neutrons and the spin by switching the choice of the post-selection: (i) The first lines indicate that the neutrons are found to be localized in different paths by switching the choice of the post-selection; they are found in the path I and II by applying the post-selection \({|{\Psi ^{+}_f}\rangle }\) and \({|{\Psi ^{-}_f}\rangle }\), respectively. (ii) The lines of the second part of the equations indicate that the spin in the different paths is found to be affected by switching the choice of the post-selection; the spin in path II and I is affected by applying the post-selection \({|{\Psi ^{+}_f}\rangle }\) and \({|{\Psi ^{-}_f}\rangle }\), respectively. Note that, in both choices of the post-selection, neutron and spin are localized in different paths, i.e., the location of the cat itself and its grin are interchanged by switching the choices of the post-selection. Since measurement of the locations of the neutron and the spin in the interferometer can be carried out independently of the delayed-choice process, the picking of a direction for post-selection, the influence of the delayed-choice on the preceding measurements can be investigated. We would like to point out that the experimental proposal in a recent publication³⁵, contains a delayed choice scenario, too. The difference to the experiment presented in this report is that the authors of³⁵ suggest a setup where two properties of the same system, represented by two non-commuting observables, are separated. In contrast to that, we deal in our experiment with the separation of one property from the system itself, hereby constituting the phenomenon of disembodiment. Further we would like to point out that in their Gedanken-experiment the effect of a change in the pre-selection is discussed that in our view has no retro-causal implications.

The experiment was carried out at the S18 silicon-perfect-crystal interferometer beam line at the high flux reactor at the Institute Laue Langevin. A schematic view of the experimental set-up is shown in Fig. 2.

Year 2014 face_with_colon_three If black holes have infinitely small sizes and infinitely density this also means that string theory would also solve the infinitely small problem because now we know that infinitely small sizes exist and if that exists then so does infinite energy from super string essentially filling out the rest of the mystery of the God equation. This means that computers could be infinitely small aswell saving a ton of space aswell.

If you’ve wondered how big is a black hole? then you’ve come to the right place! Learn about the sizes of black holes and the multi-layered answer.

The Big Bang may have not been alone.

The Big Bang may not have been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.

Dr. Emily Rice, an Associate Professor of Astrophysics at the Macaulay Honors College of CUNY and resident research associate in the Department of Astrophysics at the American Museum of Natural History (AMNH), is one of the keynote speakers at the TEDxCUNY conference to be hosted on March 10, 2023.

Dr. Rice is extremely involved in the scientific community through her role as a researcher and professor. Dr. Rice co-founded the research group Brown Dwarfs in New York City (BDNYC) with Dr. Kelle Cruz from CUNY Hunter College and Dr. Jackie Faherty from AMNH. Brown Dwarfs are objects that have masses between giant exoplanets and low mass stars. Dr. Rice explained there was a lot about Brown Dwarfs that scientists were yet to explore and understand.

“The three of us started this research group following a small project we had collaborated on,” Dr. Rice said. In 2010, Dr. Cruz had started their work with Hunter College, Dr. Rice was wrapping up her postdoctoral work, and Dr. Faherty was finishing up graduate school. “We all happened to be in New York City at the time, and we were all working with Brown Dwarfs, so we decided to create a research group focused on these substellar objects,” Dr. Rice remarked.

A team of researchers led by the University of Innsbruck have observed a quantum tunneling effect in experiments that build off 15 years of research into such reactions and marks the slowest charged particle reaction ever observed until now. But while such chemical reactions have only been theoretical up to this point, can it be achieved in real-world experiments?

“It requires an experiment that allows very precise measurements and can still be described quantum-mechanically,” said Dr. Roland Wester, who is a professor of theoretical *physics at the University of Innsbruck, and lead author of the study. “The idea came to me 15 years ago in a conversation with a colleague at a conference in the United States.”

One of the most fundamental rules of physics, undisputed since Einstein first laid it out in 1905, is that no information-carrying signal of any type can travel through the Universe faster than the speed of light. Particles, either massive or massless, are required for transmitting information from one location to another, and those particles are mandated to travel either below (for massive) or at (for massless) the speed of light, as governed by the rules of relativity. You might be able to take advantage of curved space to allow those information-carriers to take a short-cut, but they still must travel through space at the speed of light or below.

Since the development of quantum mechanics, however, many have sought to leverage the power of quantum entanglement to subvert this rule. Many clever schemes have been devised in a variety of attempts to transmit information that “cheats” relativity and allows faster-than-light communication after all. Although it’s an admirable attempt to work around the rules of our Universe, every single scheme has not only failed, but it’s been proven that all such schemes are doomed to failure. Even with quantum entanglement, faster-than-light communication is still an impossibility within our Universe. Here’s the science of why.

Published in the journal Quantum Science and Technology, Saleh’s research focused on a novel quantum computing technique that should — at least on paper — be able to reconstitute a small object across space “without any particles crossing.”

While it’s an exciting prospect, realizing his vision will require a lot more time and effort — not to mention next-generation quantum computers that haven’t been designed, let alone built yet. That is if it’s even possible at all.

Counterportation can be achieved, the study suggests, by the construction of a small “local wormhole” in a lab — and as the press release notes, plans are already underway to actually build the groundbreaking technology described in the paper.
