The central aim of The Solid-State Qubits Lab is to develop a quantum network based on a few entangled qubits. To achieve this goal, we have divided our efforts into three main focus area.

In Focus area 1, we search for new defect-based qubits in diverse host solid-state materials. To efficiently perform this task, we use a material design approach, in which a theoretical prediction on promising defect candidates is first made, followed by experimental verifications including materials growth and characterizations.

In Focus area 2, we concentrate on the coupling mechanism and connectivity of a few qubits. We particularly consider strong coupling schemes relying on nano-mechanical vibrational modes and microwave cavity modes, which are suitable to realize quantum network and quantum simulations.

In Focus area 3, we develop chipset devices based on the new defects and host materials studied in Focus 1 and demonstrate multi-qubits entanglement based on the coupling mechanism explored in Focus 2. We study amplification and decay of generated entanglement in a quantum node of few qubits and examine long-range interaction between the quantum nodes using mechanical modes or microwave cavity modes.
