Here is what you will learn when you read this story:
- Greenberger’s paradox – Horne – Ziilinger (GHz) describes how quantum theory cannot be described by local realistic descriptions.
- A new study brings this GHz paradox to new heights to see how No–Classic the quantum world can get.
- In the process, their experience included photons in 37 dimensions, still preventing science in this strange quantum rabbit hole in the hope of finding applications in these large systems.
Classic and quantum mechanics do not really get along because the science of the subatomic can become weird. Take, for example, quantum tangleWho says that the state of a particle can be determined by examining the state of his tangled pair whatever the distance. This strange fact flies in front of classical physics, and even led Albert Einstein To describe this quantum oddity as “a frightening action at a distance”.
This is called “quantum non-locality”, where objects are influenced on distances (seeming beyond the speed of light) while classical physics follows local theory, the idea that objects are influenced by their immediate environment. This is a fairly clear fracture, as explained by the famous non -GO theorem known as the Greenberger – Horne – Zilinger (GHz) paradox, which essentially details how quantum theory cannot be described by a local realistic description.
Named for physicists who described the paradox in 1989, GHz type paradoxes show that when particles can only be influenced by proximity, they produce mathematical impossibilities. As New scientist reportsThe paradox can even be expressed by a calculation where 1 is equivalent to -1. This paradox is useful for showing how quantum properties cannot be described using conventional means, but a new article published in the journal Scientific advancesdecided to see how strange these paradoxes could be.
Essentially, an international team of scientists wanted to see how UN-The classic light particles could obtain -and the results were perhaps stranger than the authors initially planned. This extremely technical experience produced photonsor particles of light, which existed in 37 dimensions. Just like you and I exist in three dimensions – plus an additional temporal dimension – these photons required 37 similar reference points.
“This experience shows that quantum physics is more non-classic than many of us thought,” said Zhenghao Liu of the Denmark Technical University, a co-author of the study, said New scientist. “It could be (that) 100 years after its discovery, we always see only the tip of the iceberg.”
Pulling this is not an easy thing to do because Liu and his team had to feed a version of the GHz paradox in coherent light – even in color and wavelength– So that they can easily handle the photons. This has mainly resulted in “non -classical effects in the quantum world” that has ever been created, said Liu New scientist.
“We believe that this work has opened several avenues for future research,” write the authors. “We hope that our results can be used to create even stronger quantum advantages in large systems.”
In other words, if we have not discovered the tip of the iceberg, simply imagine which quantum breakthroughs are hidden just below the surface.
