Role of Microwave Technologies in Quantum Computing

#quantum-computing #microwave-circuits

This webinar highlights the role of microwave technologies in quantum computing. It begins with a quick review of the basic differences between classical and quantum computers. It proceeds by considering the fundamentals of qubits and quantum gates as essential components of microwave quantum computers. It then examines superconducting transmon resonant circuits as a common microwave implementation of quantum bits (qubits). Finally, it discusses practical implementations and explains how they operate. In particular, a basic superconducting qubit is examined along with its control and readout microwave circuits. The simplest quantum gate, the controlled NOT (CNOT), is then discussed. Relevant microwave components, such as tunable couplers and ultra-low-noise amplifiers, are examined to highlight the importance of advanced microwave technologies in the reliable implementation of quantum computers.
