摘要：Devices capable of storing and processing quantum information have the potential to create revolutionary technologies. The performance of such devices can be significantly improved by engineering the interactions between photons and stationary quantum bits (qubits). This talk will explore two solid-state approaches for quantum information processing applications.

First, I will discuss our approach to building quantum network nodes based on a new color center in diamond, the neutral silicon vacancy (SiV0). Its long spin coherence times and efficient optical transitions make it a promising candidate for quantum memories in a quantum network. A key advantage of this solid-state platform is its ability to be integrated into scalable devices. We have developed a hybrid photonic platform that enhances the photon emission of SiV0 and enables on-chip telecom-band frequency conversion.

In the second part, I will present our efforts to realize ultrastrong coupling with superconducting quantum circuits. By combining van der Waals materials with superconducting transmon qubits, we aim to explore multi-qubit dynamics in the ultrastrong coupling regime, potentially leading to enhanced gate fidelity and longer coherence times for quantum information processing applications.
