RIKEN Center for Quantum Computing Hybrid Quantum Circuits Research Team
Team Leader: Atsushi Noguchi (Ph.D.)
Research Summary
In superconducting circuits, various quantum functions, such as qubits and parametric circuits, emerge due to the large nonlinearity of the Josephson junction without any loss. These systems, which combine these high-performance quantum systems with other quantum systems, are called hybrid quantum systems. We aim to construct high-lifetime quantum systems, such as microwave resonators and trapped electrons, and observe and control them with superconducting circuits, in order to establish quantum control techniques that greatly outperform existing quantum systems and to demonstrate quantum error correction codes using these techniques.
