How does the superposition of states come up in Bohmian Mechanics?
In Bohmian Mechanics, it assumes a universal wave field in which particle's motion can be calculated using Newton's law of motion:
\begin{equation}
m\frac{d^{2}x}{dt^{2}} = - \nabla(V+U)
\end{...

Is there a way to measure the degree of superposition of a quantum state?
I am wondering if there is a way to calculate the amount of superposition that a quantum state is in. For example, if I have a $2$-qubit quantum system, with basis $\mathcal{B} = \{|00\rangle, |01\...

Does something prevent superposition at our scale?
I often encounter the argument that quantum mechanics reduces to classical mechanics at sufficiently big scales, as soon as h becomes sufficiently small respect to the actions involved. I clearly ...

Do qubits need to be in superposition to be entangled? [closed]
Do qubits need to be in superposition to be entangled?
Put another way, can qubits be entangled but not in superposition?

Do multi-state of entangled particles exists?
I haven't taken any course in Quantum mechanics. But I felt "Quantum Entanglement" quite interesting. I recently read some articles on it. But I am not sure if I understood anything or satisfied with ...

What happens if we measure the two entangled systems of the Bell test simultaneously?
Consider the Bell state $|\psi\rangle =\frac{|00\rangle +|11\rangle}{\sqrt{2}}$.
When measuring one of the individual systems, the superposition is projected onto one of the eigenstates $|00\rangle$ ...
