RIKEN Center for Emergent Matter Science Quantum System Theory Research Team
Team Leader: Daniel Loss (Ph.D.)
Quantum System Theory Research Team is working on the quantum theory of condensed matter with a focus on spin and phase coherent phenomena in semiconducting and magnetic nanostructures. In particular, the team investigates the fundamental principles of quantum information processing in the solid state with a focus on spin qubits, superconducting qubits, and Majorana fermions. This involves the study of decoherence in many-body systems and scalable quantum computing architectures based on surface codes and long-distance entanglement schemes. The group also studies nuclear spin phases and many-body effects in low-dimensional systems with spin orbit interaction, and quantum transport of magnetization.
