The “strangeness” that can inextricably connect two distant particles can, after all, be equivalent to an equally strange property of only one. This can help us understand how quantum objects remain inextricably linked through intertwining.
A study at the beginning of the month in the Physical Review Letters found a connection between two counter-intuitive quantum properties.
The investigation team led by Jianqi shengfrom the University of Xiamen, China, studied two examples of foreign quantum behaviors, known as Contextuality and Non-Locality.
Contextuality means that the result of a quantum object measurement depends on the other measurements being done at the same time. Think of a french – The spicy flavor also depends on the other ingredients that are in the recipe.
Non-locality, on the other hand, means that the measurement of the properties of a quantum object, such as a particle, can immediately reveal something on another object, even when it is very distant.
Surprisingly, this study has shown that one of these properties can be converted in another.
As details, researchers used particle pairs of intertwined light, or photons, placing each photon in a quantum state with intricate rotational properties: if they were part of a beam of light, this beam would have been twisted in the form of a propeller.
The more twisted the photons, the more intricate their quantum states would be. In fact, they could create photons whose quantum states had up to six dimensions, behaving as if the photon existed in a six-dimensional quantum world.
It could be said that Francesinha had many layers of flavor.
Since the photons were intertwined, The team knew that it would experience non-locality. To relate this to the contextuality, it used a mathematical revenue for the conversion between non-locality and contextuality, previously developed by Adam Cabello at the University of Seville, in Spain.
Cabello created a formula to which researchers could turn on their measurements to see if the conversion worked. The new study found that yes.
“When I started [estudar] All of this many years ago, these experiences were a dream. And the experience really corresponds to the quantum forecast. It is an extremely beautiful confirmation that nature is really following quantum mechanics with an incredible degree of precision, ”Cabello told New Scientist.
Interlacing can also be multidimensionalso Sheng states that the ability to put the photons in multidimensional states allows them share many correlations with your partner – Which was fundamental to make this test unmistakable.
In addition to helping scientists understand why quantum particles can stay, this study can have practical implications, such as technologies, such as ultra-segura quantum communication, efficient quantum encryption and some types of computing.
