Jann’s research focuses on the development of scalable solid-state quantum computing architectures.

While quantum computers have been realized with small numbers of qubits, practical and fault-tolerant operation requires systems with significantly larger qubit counts. Solid-state qubit platforms are particularly promising in this context, as they leverage decades of technological advances from the semiconductor and microelectronics industries.

Jann’s work lies at the interface of the two most established solid-state qubit technologies: semiconductor spin qubits and superconducting qubits. In the Yacoby lab at Harvard, Jann is involved in two research projects that address key challenges in scaling up quantum hardware.

**Spin qubits in germanium**  
Jann studies germanium-based spin qubit devices, focusing on the development of optimized qubit control techniques. The goal is to improve device performance and establish approaches that enable reliable operation and scalability of germanium-based spin qubit systems.

**Scanning resonator microscopy**  
As part of the multiprobe research effort, Jann is developing a scanning probe microscope incorporating a superconducting sensor. This approach will enable rapid and spatially resolved characterization of superconducting qubits on the wafer scale, which is an essential capability for the scalable deployment of these systems.
