Understanding quantum and classical system interconnections

In this section, we'll review how the most quantum computational systems are integrated with classical systems. Since quantum computers do not have ways to store qubit information or any sort of quantum storage, there is a dependency on classical systems to provide persistent storage for information that is sent to or received from a quantum computer.

Since most data sources, whether they are from data repositories or remote sensors, originate from classical sources, there is a need to prepare the data to be used in a quantum system. Likewise, the results from the quantum systems need to be returned, not in a quantum state but in binary form, so that they can be read back to a classical system for any post-processing that's required.

This hybrid or interconnectivity between classic systems and quantum systems is what we will be reviewing in this section so that you understand how both systems work together...
