Topic: Superconducting qubits for large-scale quantum computers - Status of development in Korea and global trend

 

Abstract:

 

Quantum computing is attracting much attention recently due to the possibility of superior computing capacity compared with the classical computers. Quantum computing is based on the advantage of quantum mechanical phenomena in qubits; quantization of states, superposition of the two states, and entangement between qubits. Among the possible platforms for the qubits, superconducting qubit has several advantages; fast gate operation, relatively long coherence time, high gate fidelity, best scalability of the superconducting circuits using semiconductor fabrication technology, mature and stable precision microwave and cryogenic technology, and easy-to-operate and reliable hardware. Therefore superconducting qubit is one of the most widely studied platform worldwide.

 

In the superconducting qubit, we control the two lowest energy states in the superconducting circuits, and its energy difference is equivalent to about 250 mK. Therefore we need to protect the qubits well from the environment thermal and electromagnetic interferences. And accurate and precise control of microwave pulses and quantum-limited measurement of microwave signals are needed for high-fidelity operation of the qubit system.

 

 

In the talk, I will introduce the basic concept of the superconductivity-based quantum computing, design and fabrication of superconducitng qubits, microwave control and measurement technology, and cryogenic and microwave components of the quantum computing system. And, the ongoing project for developing superconducting quantum computing system in Korea, and global trend for higher-performance quantum computing will be introduced.
