According Relativity, nothing moves faster than light, and the speed of light is about c=3x10⁸ m/s. So, the speed of gravity is equal c, in Relativity. When the spin of an electron changes, the spin of other electron does change instantaneous.

It shows information moves faster than light in atomic level. We can accept nothing moves faster than light and transfer of information does not obey of physical laws. But it is not a scientific looking on nature.

How can we explain this phenomenon? We must accept that information move faster than light, but how it does?

Is there any signal other of electromagnetic waves in nature?

Surely, it is gravity.

Gravity
According TO CPH Theory, gravity is a currency among objects. For example consider the interaction between the earth and the moon:
Earth has a gravitational field. The gravitational field is formed by gravitons that are moving toward the earth and they are interacting with each other. Suppose the earth is alone and there are no interactions between earth and other bodies in universe. When gravitons reach the earth, the earth absorbs them. Then gravitons obey all forces around them. But the earth is not alone and it has interaction with other bodies. Take a look at earth and moon. There are two fields; one is around the earth and the other one is around the moon. When a graviton reaches the earth, the other one moves toward the moon and pushes the earth toward the moon. (Remember flow and ebb). Also when a graviton reaches the moon, the other one moves toward the earth and pushes the moon toward the earth. So earth (In fact every thing) is bombarded by gravitons continuously. 

But what is CPH?

Definition of CPH
Suppose there is a particle with mass of m that is moving with speed Vc in an inertial frame. And Vc>c and c is the speed of light. So, its linear momentum gives mVc. It is Called CPH (Creation Particle Higgs).

Principle of CPH

CPH is a particle with constant mass m and moves with constant speed Vc. 
CPH has the momentum of Inertia I. In any interaction between CPH and other particles/forces, the amount of Vc does not change, so;

gradVc=0 in all inertial frames and any space

Let's return to transfer of information in structure of atom.

Look at two electrons A and B in structure of an atom. They are replying gravitons continuously as everything in universe.

When a graviton reaches of A to B, its spin and direction transfers any all information of A to B.

So, if the spin of A changes, graviton shows it to B.

We can calculate the speed of graviton. Suppose distance d between two electrons is d=1x10^-15 m (diameter of atom)

Graviton does pass d at least time t. The least time is Planck's time T=5.39x10^-44 s.

So, the speed of graviton V gives by following relation;

V=d/T=(10^-15m)/(5.39x10^-44s)=2x10²⁸ m/s

So, the speed of graviton is about 10²⁰ times as c, or

V=10²⁰c

please consider that Vc>V, because graviton has spin and Vc is the speed of CPH when it has not spin, remember:

gradVc=0 in all inertial frames and any space
