We're not really near the point where most genuinely interesting quantum algorithm can be implemented on a quantum computer. We don't have enough high fidelity qubits. That situation is changing. Rose's law is an analog here to Moore's law which says that the number of qubits doubles roughly every 18 to 24 months. Coherence is also an issue, but that's also improving. Aside from these considerations, it is very common even for the algorithms and protocols which are small enough to be implemented, it is very common for one group to do the theoretical work behind the algorithm and then a bit later a more hands-on group does the actual physical implementation.
