An experience with 37 dimensions, in search of the most paradoxical quantum states of particles, showed how strange quantum physics is.
A study this Wednesday in Science Advances showed the “Guts” Strange of Quantum Physics.
As details, the investigation team has focused on the Greenberger-Horne-Zilinger (GHz) paradox, which shows that quantum particles can remain linked to long distances for over 30 years.
In the simplest version of the paradox, three particles are connected through the special connection that allows observers to learn something about a particle by interaction with the other two.
As shown in mathematical evidence, a situation in which particles can only influence each other when they are very close – in other words, when the so -called ghostly distance action is prohibited – leads to mathematical impossibilities.
In the 1990s, physicists realized that the only way to avoid these impossibilities was to accept that particles can participate in what New Scientist describes how “Quantum scary action”.
In the new study, the researchers set out to build the most extreme version of this paradox to date. Specifically, they wanted to find photon states, or light particles, whose behavior in a GHz experience was very different from that of purely classic particles.
Their calculations revealed that photons had to be in quantum states as intricate as if they existed in 37 Dimensions.
That is, as your position at this time has to be determined with reference to three spatial dimensions and a temporal dimension of our world, The state of each photon had to use 37 such references.
The researchers then tested this idea by translating a Multidimensional version of GHz paradox in a series of very coherent light impulses – Extremely uniform light in your color and wavelength – which they could then manipulate.
“This experience shows that Quantum physics is more non-classical than many we thought. It may happen that, 100 years after its discovery, we are still seeing the tip of the iceberg, ”he told New Scientist the investigation leader Zhenghao liufrom the Technical University of Denmark.
Liu said the next step was faster coding information in quantum states similar to those your team has studied.
This work can also have implications in the way quantum states of light and atoms are used for information processing, as in quantum computing.
