Quantum Superposition!!! The reason behind ghostly movement of elementary particles!!!!
Will you believe if I tell you that
you can be present in Delhi and London at the same time???
Certainly you answer will be
no….right???
But believe me if you can reduce your
size to quantum level and go to the quantum world then, you can be present in
both the locations at the same time.
Bizarre….right????
Certainly, most phenomenon in quantum
world are bizarre on their own. They are completely different from our ‘common
sense’.
The property of quantum objects to
exist at different positions or at different quantum states at the same time is
called quantum superposition.
Quantum superposition states that an
object that is not being observed exists in all possible states at once or we
can call that ‘it is in superposition’. To more simplify it, we can also say
that, due to quantum superposition a particle which is not observed can have
multiple velocities and can be at different places at once.
Let’s understand this with a simple
experiment…
Assume that you threw two balls with
same power and velocity at that same direction in the same conditions. What do
you expect???
Our common sense will say that both
of the balls will land at the same place…right???
But, imagine what will happen when
you threw two electrons instead of balls???
Will you get the same result???
The answer is simple
no….why???....because of Quantum Superposition.
When you throw the first ball and
detect it with a detector at a particular
position, you can’t comment that the
ball was travelling along the same path for
all the time till it reached here. So,
if you throw the electron next time with all
the same parameters then, you can’t guarantee
that the electron
will travel in the same path.
That’s the trick of superposition.
We don’t encounter superposition in
our day to day life as in macroworld , objects continuously encounter with the
environment and thus act like an observer, and that’s why the wave function
collapse and occur continuously occurs.
