Sure — but we’re not anywhere near that limit.

Also, you can entangle remote quantum systems which is a different paradigm for distributed computing than you can do with a classical computer.

With classical computers, you get a summation of joining the two systems; with quantum computers, you get the product of joining the two systems.
