The catch with Dr. Clauser’s discovery and quantum mechanical description of this frightening act was that the correlations didn’t emerge until after individual particle measurements, when the physicists compared their results after the fact. Entanglement seemed real, but it couldn’t be used to communicate information faster than the speed of light.
Dr. Clauser spent most of the decade worrying about loopholes he might have overlooked. One possibility, called the local loophole, was that the lab tools might have been leaking information to each other.
Enter d. Aspect who He is now a professor at the University of Paris-Saclay in Paris and at the Polytechnic College in Palaiseau, France. In the 1970s, on his way to his Ph.D., he spent three years doing national service requirements by teaching in Cameroon, ditching quantum mechanics in his spare time. In an interview with the Nobel Committee, he said he returned to France ready to take on the challenge of Dr. Bell’s work.
In 1982, Dr. Aspect and his team at the University of Paris attempted to overcome the Dr. Clauser loophole by switching the direction in which the polarizations of photons were measured every 10 nanoseconds, while the photons were already in the air and too fast for them. to communicate with each other. He, too, expected Einstein to be right.
The results of Dr. Aspect entanglement on the map as a real phenomenon that physicists and engineers can use. The quantum predictions were correct, but there are still more potential loopholes in Dr. Clauser’s Bell experiment that must be closed before quantum physicists can claim victory over Einstein.
For example, the polarization directions were changed in the experiment of D.
At the time, Anton Zeilinger – a professor at the University of Vienna, who with his group probably emerged as the leading ringleader in quantum deception – took the baton. In 1998, he added more randomness to Bell’s experiment, using random number generators to change the direction of polarization measurements as entangled particles hovered.
