The study of the properties of small particles of nature and the applications made on the basis of this study is called quantum physics as a whole. Quantum physics is being studied continuously since 1800 AD and still many of its applications find their existence somewhere between reality and fantasy. Eminent scientists like Einstein called it frightening on the basis of its incomprehensible behavior.
In the 1960s John Stuart Bell attributed invisible variables to quantum entanglement, an application of quantum physics. He said that some invisible force is responsible for the mutual effect between two quantum substances. After this, a scientist named John Klauser conducted various experiments to prove what Bell had called unrealistic as a real phenomenon.
However, Klauser could not put these experiments into practice. After this, a scientist named Aspect started following his leaks. He proved quantum entanglement at the definitional level. Its practical application was yet to be done.
A scientist named Zellinger proved it on the basis of its practical applications and now quantum entanglement had become a concept not just a definition. The phenomenon that had hitherto been considered unreal was about to become real.
For example, a concept like teleportation was now about to take shape. Teleportation refers to a phenomenon in which physical distance is bridged. Think of it like that you are physically present in Delhi and with the help of technology your physical presence can be ensured in New York or anywhere else. This is one aspect of quantum physics. Apart from this, quantum physics can also be applied in other fields such as quantum computing, quantum communication, quantum transport etc. Allen Aspect, John Klauser and Anton Zellinger were awarded the Nobel Prize in Physics for the year 2022 for providing a solid foundation for these applications.
