Experts say it will still take many months to know if this vaccine, or others also in research, will work.

Yes. All leptons and bosons included?

So it starts from the same principle, namely a not specific location, when we trap a photon?

I understand. The particle is localized by a probability distribution.

The eigenstate interprets the observable states represented by an eingenfunction, which is characterized by a linear operator and its eigenvalue. In the case of the oscillator these eigenstates are measured in a potential well. Position is not an eigenstate. Back to the HUP. The particle identified and located by the uncertainty principle asserts the undeniable presence of particle, right? If yes the particle takes what physical form if it implies a position?

So what is the role and the advantage of involving the quantum harmonic oscillator, if there is no oscillating particle? We oscillate the Schrodinger equation as a wave function? Simpler, we oscillate a corpuscle, and not a particle?

"One is solving the problem at the quantum level" Which one is solve? "and we use the same terminology as the macroscopic problem" But there is no uncertainty principle at the macroscopic level?

Ok. I did'nt understand everything. Could you detail what this means? Which problem precisely?

But what does the oscillator oscillate?

Sorry, a probability amplitude. It's a probability amplitude into the well?

I found that: The ground state energy for the quantum harmonic oscillator can be shown to be the minimum energy allowed by the uncertainty principle. ... This is a very significant physical result because it tells us that the energy of a system described by a harmonic oscillator potential cannot have zero energy.

Then the quantum oscillator is only a of probability of presence of the particle in the form of wave, no? It's a wave probability (for to find the particle) into the well? Ok.

Split reference: When we find a particle with the Schrodinger equation, is it either stationary (fixed position), or in motion with a given velocity with the uncertainty principle?
