Dr Nemoto from NII introduces the Quantum Systems.

We have just seen the requirements for a technology useful for building a quantum computer (the DiVincenzo criteria). In this video, Professor Kae Nemoto of Japan’s National Institute of Informatics introduces us to the broad structure of a quantum computer as a machine composed of a classical control system and a set of qubits that can interact with each other.
Over the next several Steps, first we will see how the fundamental science of isotopic control affects a broad range of technologies. We will address photonic experiments, quantum dots, superconducting chips, nitrogen vacancies in diamond, and ion traps. These are the devices that create and control the quantum states that we introduced as types of state variables earlier in the course.
All of the devices you will see are real quantum computers. But how close are they to being useful systems? We will follow up with a brief discussion of the prospects for near-term computers to outperform classical systems on specific problems, then close by bringing Professor Nemoto back to discuss large-scale architectures.
