The Information Paradox and the Copenhagen Interpretation

Are quantum computers able to simulate every physical process that a classical one can simulate?

Can quantum entanglement be used to coordinate actions at "FTL speeds" without breaking causality or actual faster-than-light communication?

Is there a classical analogue to purification of quantum states?

What is the probability of obtaining the same measurement a finite time after causing a wave-function collapse with my initial measurement?

How to compute expectation value $\langle e^{iH}\rangle$ for quadratic Hamiltonians?

Qubits of higher dimension

Do channels which do not affect a subsystem always have the form $\mathcal E=\mathcal T_{\mathcal A}\otimes\text{id}_B$?

Why is the standard definition of fidelity unnecessarily complicated?

Is HaPPY code a certain type of MERA?
