Physicists found the shortest measurement to collapse a quantum state


Measuring a quantum object makes it lose its odd quantum properties, and it solely takes between 0.1 billionth of a second to 0.1 sextillionth of a second

Quantum wave perform collapse just isn’t instantaneous

The collapse of the quantum wave perform – during which quantum objects go from current inside many attainable states directly to settling right into a concrete one understood by classical physics –  doesn’t occur instantaneously, instantly difficult a longstanding textbook understanding of quantum physics.

Essentially the most infamous instance of this phenomenon is Erwin Schrödinger’s thought experiment the place a cat in a field is in a quantum state of each “lifeless” and “alive” on the identical time. Opening the field and …
