Quantum calculations on the basis of superconducting circuits

In this presentation, after explaining the basics of quantum computers, we will focus on superconducting quantum computers. First, we introduce the principles and main elements of circuit quantum electrodynamics (cQED) as a basis for understanding superconducting quantum computer technology. Then, we discuss the concept of resonant waveguides and artificial atoms, which are the cornerstones of cQED, and show how these structures can exhibit quantum behavior and revolutionize quantum computing and information processing. Also, we compare cQED with quantum cavity electrodynamics (CQED) and highlight its advantages. Next, we will examine superconducting quantum computers. This platform provides the possibility of engineering qubits by changing the geometry and topology of superconducting circuits and ease of control, reading and adjustability. After introducing the basics of gate-based quantum computing, we will examine the quantum layer and confirm the DiVincenzo criteria in the context of superconducting quantum computers, and we will introduce the types of superconducting qubits, the methods of applying single and double qubit gates and their reading. By following this presentation, you will gain a comprehensive understanding of superconducting qubits and the main ideas in their control and readout.
