Quantum Computing isn't just expensive, it's (nearly?) impossible and has no known benefits. Why make quantum computer ?

It has a number of known benefits. VASTLY faster solution of some hard problems is one. (the most famous of which is factoring). > > Why make quantum computer ?

In theory, or in practice ? As I understand it, no one has ever streamed qubits.

At present obviously in theory. But your second comment "no known benefits" was not about practice. > > As I understand it, > no one has ever streamed qubits. No idea what "streamed qubits" means.
