Presently, there are 7 layers of OSI(Open Systems Interconnection) model in telecommunication:-
1. Physical layer
2. Data link layer
3. Network layer
4. Transport layer
5. Session layer
6. Presentation layer
7. Application layer
So, the root question is can the no. of elements in the 7 layers of OSI model be decreased to fewer elements? And if yes. Then what are the elements can be eliminated in the communication networking?

Sir!
In classical communication system, for every information to be sent between parties, signal has to be processed through the 7 layers,i.e., every time the message has to cover thousands of miles via optical fibers and electronic devices to be conveyed across. So, a number of electrical and electronic elemental devices are needed. But, in quantum communication, the central idea is conveying entangled qubits(say photons) and the rest will be take cared by the entangled qubits due to quantum mechanics and hence electrical and electronic devices will only be needed to convey the entangled qubits once. So, the circuit elements in the OSI model should decrease but the 7 layers stay the 7 layers.
