Sorry Einstein, new quantum research proposing 'ghost effects' is real

In a landmark study recently, scientists at the Delft University of Technology in the Netherlands have demonstrated one of the most fundamental phenomena of quantum theory.

The most fundamental phenomenon of quantum theory

That's what Einstein once called ' temporarily spooky action at a distance' translating as 'spooky effect from afar' . It is easy to understand that this method allows two objects to be separated regardless of a large distance, from several meters or hundreds of light years can immediately interact and influence each other.

Einstein insisted on not believing in the "spooky effect" method . He refused to accept the view that the universe could behave in a strange and seemingly random way. In particular, Einstein expressed a ridicule of theory that two separate particles could be "entangled" into one another, that a particle could interact with another particle immediately at any distance. All the uncertainties of quantum theory are comparable to that of God playing dice.

Visualize the "remote ghost effect" of two objects.

However, since the 1970s, a number of other scientists have done a lot of accurate experiments to erase these doubts. They all proposed that the two particles could be "entangled" before, and they could even interact even on either side of the universe.

In 1982, a group of physicists and mathematicians were able to witness 'ghostly effects' in mathematics. And by 2015, we have the first experiment that has been able to affirm once again this.

This experiment was published last week in Nature. It can be said that it dealt a critical blow to one of the basic principles of classical physics. The 'local' calculation in classical physics says that an object can only be affected immediately by its surroundings.

The group of scientists who successfully conducted the experiment was led by Ronald Hanson, a physicist from the Kavli Nano Science Institute of the University of the Netherlands. Besides, they also have the participation of many partners from Spain and England.

The experiment called 'loophole-free Bell test' was referenced based on the proposal of physicist John Stewart Bell in 1964. At that time, Bell believed that this was a method that would prove 'ghost effect'. Monster " real.

"Test experiments have been around since the late 1970s, but they always have doubts and need to add the necessary assumptions ," said Dr. Hanson. ' Only until our experiment did we really claim that' ghost effects 'are real'.

The Dutch team completely eliminated hidden variables that could provide explanations of the interaction of each other at a distance. Therefore, the final explanation is for 'spooky action' . They made two electrons interact with each other at a distance of 1.3km.

In it, scientists use two diamonds placed on the campus of Delft University. The distance between them is 1.3 km. Each diamond contains an electron trap. An ordinary electron carries an 'electron spin'. And they use laser waves to measure the 'spin' of two electron particles as they interact with each other.

In fact, the detectors have detected two "entangled" particles. That's the term scientists use to describe two particles that are far away from each other without being independent.

The team is testing the experimental equipment.

'I think this is a beautiful, ingenious experiment and it will drive the entire field of quantum physics forward' said David Kaiser, a physicist from MIT. Leonard Succkind, another theoretical physicist from Stanford University, said: 'This experiment far surpassed what I could imagine when I first stepped into physics. It is extremely impressive. '

Indeed, the Dutch scientists' experiment is not merely a verification of quantum mechanics theory. Because quantum mechanics can have a huge impact on modern technology, it also opens up a new step towards a great application known as 'Quantum Internet'. Dr. Hanson began envisioning an information network using particles to connect the entire world. Such a network can provide almost absolute security.

However, there are still some physicists who are skeptical about the work published in this Nature. Dr. Keizer is also one of them, he said: 'This test has closed 2 of the 3 major holes, but 2 is not 3' yet . He thinks that the electronic system and the scientists used to add randomness to the experiment could be a flaw. And to really fix it, he is planning to implement a project in 2017 next. So let us wait and see if the 'last hole' can be closed to open a new future with 'Quantum Internet' !
