For questions about the principle and application of quantum entanglement. It is a physical phenomenon which occurs when pairs or groups of particles are generated, interact, or share spatial proximity in ways such that the quantum state of each particle cannot be described independently of the state of the other(s), even when the particles are separated by a large distance—instead, a quantum state must be described for the system as a whole.

How to deal with entanglement using quantum relativistic equations?
When discussing relativistic quantum mechanics, the single particle picture is dropped completely
Not completely. You can still consider 0-particle and 1-particle states. The 0-particle state is usu …

Is the balanced superposition of all three-qubit computational basis states entangled?
$$
\frac{{\sqrt 2 }}{4}\left| {\left. {000} \right\rangle } \right. + \frac{{\sqrt 2 }}{4}\left| {\left. {001} \right\rangle } \right. + \frac{{\sqrt 2 }}{4}\left| {\left. {010} \right\rangle } \righ …

Can qubits be entangled without being classically corelated?
Is this state entangled? $$\frac12 (|000\rangle + |011\rangle + |101\rangle + |110\rangle)$$
Yes.
If it is, how would I know,
You know by comparing to the most general three-qubit unentangled stat …

Understanding the Hadamard gate and what is meant by qubits
The Hadamard Gate transforms $ |0 \rangle$ into $|+ \rangle = \frac{|0 \rangle + |1 \rangle}{\sqrt{2}}$ and $|1 \rangle$ into $|- \rangle = \frac{|0 \rangle - |1 \rangle}{\sqrt{2}}$. From what I unde …

Entanglement and superposition illustration
Is there an example that would demonstrate the importance of both entanglement and superposition? … I just don't want to say "just trust me entanglement can be used to speed up computations"...
Yeah, please don't say that. It's not even wrong. …
