Encode qubits in the states of electron spins. Develop scalable architecture for single-qubit control, two-qubit interaction, and qubit readout. Collaborate with semiconductor industry on foundry-made spin qubits. 

Study quantum many-body problems by performing experiments on quantum dot arrays. Realize programmable analog quantum simulators on intermediate-scale devices. Validate quantum simulators using Hamiltonian learning methods. 

Couple spin states to microwave photon, optical photon and acoustic mode. This can be used as a mechanism for quantum transduction.
