Python -O won’t magically make every script faster, but in the right workloads it’s a free win—here’s how to test it safely.

Why write ten lines of code when one will do? From magic variable swaps to high-speed data counting, these Python snippets will transform your code.

We consider the computation of the entanglement-assisted quantum rate-distortion function, which plays a central role in quantum information theory. We propose an efficient alternating minimization ...
