For questions about schemes to prove that quantum devices can, at least in principle, be exponentially more efficient than their classical ones. Also often referred to as "quantum computational advantage" or "quantum supremacy". Typical examples are sampling problems such as boson sampling and random circuit sampling.

How does a quantum computer execute a process by leveraging superposition?

I understand in plain terms superposition and entanglement, but I'm very unclear how either of these could work as a means to increase computation power. A helpful metaphor is that of the maze. A norm …
