Path Breaking Study Reverses Time in Quantum Computer
5Schrodinger’s equation governs the probability of existence of particles in a local region
It is Schrodinger’s equation that governs
6The Heisenberg Uncertainty Principle
There is another law of quantum mechanics called the Heisenberg Uncertainty Principle that states it is not possible to know the position and momentum of a given particle since in the universe, everything behaves like waves and particles simultaneously. What the researchers tried was to test the spontaneous probability of time reversal and see if that could happen. The example given was the billiard ball break after it leaves the triangle shape with the balls moving in all directions which is an analog for the second law of thermodynamics that states how an isolated system can go from order to chaos. In a time reversal scenario, the balls will go from order to chaos and back to order again.
7The research team tries the impossible
The research team then tried to see if they could make this happen spontaneously in the lab and in nature. They began the
8Time reversal of an electron would take just 1/10,000 billion of a second
The research then tried to make a probable estimation of this occurrence with relation to a real-world electron due to random fluctuations. For example, taking into account the entire lifetime of the universe, (13.7 billion years) if one were to make an observation of 10 billion localized electrons every second, then you would see that localization just once. To revert the quantum state of those electrons back into the past would take just a 10 billionth of a second. That’s roughly the time taken for a light to turn green and a person honking behind or almost a blink of the eye.
