Upper bound on entanglement entropy of a Product State for any possible partition of the Joint System

Too long for a comment, partially an answer, but the question may need to be updated in response to this. For $ n$ qubits, we expect the entanglement entropy to be upper bounded by $\log n$, so $\log ...

Is quantum mutual information an entanglement measure?

Coherent information is the measure of quantum correlations. Positivity of coherent information indicates that quantum correlations are present. But this is not an iff relation. Coherent information ...

Energy cost of quantum computation

Thermodynamics matters in quantum algorithms in the following sense. There is a hidden exponential "energy space" kind of cost in many quantum algorithms. For example, the Shor's algorithm ...
