Is idempotency, $\rho^2=\rho$, a necessary and sufficient condition for $\rho$ to be a pure state?

How can work be generated from quantum correlations?

Schmidt decomposition - example

So is quantum entanglement actually FTL "communication" or is it mundane pre-determination?

Is this news article about quantum radar legit?

Optical coherence versus quantum coherence

Numerical Simulation of Stochastic Master Equation using Stochastic Schrödinger Equation (Wave Function Monte Carlo)

How exactly does the proof of Bell's theorem fail if you remove the locality assumption?

In a Bell scenario, why can correlations be nonlocal only if there are at least two measurement settings to choose from?

If spontaneous symmetry breaking only occurs in infinite systems, why do we observe similar effects in finite systems?
