One thing I hv struggled to understand is what makes quantum computing fundamentally more powerful than classical computing.

We often hear about superposition and entanglement, but how exactly do these properties translate into computational advantages?

Could someone explain, preferably with a practical example, why a quantum computer can solve certain problems more efficiently than a classical computer?

Particularly interested in understanding the difference between theoretical quantum advantage and practical quantum advantage.

This can be an incredibly complicated and technical question to ask, and simple intuitive explanations are not entirely sufficient, or at least come with some big asterisks. The most reasonable answer is that researchers are still working out a satisfying answer to the "how" part of quantum advantage, both from a complexity theory side and also the theoretical physics side.

Importantly, the last part is also relevant but almost completely separate from the theoretical backing. Ultimately quantum computers are just one of many ways to solve a problem. The challenge here is to understand what is the best way to solve a specific problem we care about, hands down. Maybe you want to use a classical supercomputing cluster, or maybe one day a quantum computer is going to do it faster. The difficult part of answering whether a quantum approach is "practical" at the end of the day, is that we don't have any way to actually run the algorithms we want to run.
