Quantum mechanics describes the microscopic properties of nature in a regime where classical mechanics no longer applies. It explains phenomena such as the wave-particle duality, quantization of energy, and the uncertainty principle and is generally used in single-body systems. Use the quantum-field-theory tag for the theory of many-body quantum-mechanical systems.

If we can't clone quantum states, then how does stimulated emission work?
In short, you cannot have stimulated emission without spontaneous emission (hermiticity requirement) . The spontaneous part will destroy the fidelity of your copying

I am learning Quantum Mechanics and I have some questions about some basic concept
I will give you an example from classical wave theory.
Take Melde's experiment with a rope where you can have different modes in this rope. Those modes are discrete, like say a photon in a box. And yo …

If wavefunction is just a probability function, how does an electron interfere with itself?
An electron can interfere with itself. there have been experiment of interference with single electron.
Saying that an electron is alway a particule is then wrong.
The wave function is the "best" wa …

Stimulated emission and No-cloning theorem
I have a little trouble with the simulated emission. I know of the no-cloning theorem which states that it is not possible to duplicate any state.
One the other hand, I know about the stimulated emiss …
