Research projects
Quantum information with trapped ions
We carry out quantum computing and quantum simulation experiments with a string of ions confined in a linear Paul trap. We are interested in the following topics:
Robust control of the ions' internal and external degrees of freedom
Realization of high-fidelity quantum gates
Implementation of hybrid quantum-classical algorithms
Investigation of quantum many-body physics of a spin system
Nanofabrication of quantum computing chips
We develop scalable quantum devices using state-of-the-art nanofabrication technologies. Our research group aims to fabricate and characterize:
Scalable ion-trapping chips
Superconducting qubits with long coherence times
CMOS-based quantum devices
Neuromorphic semiconductor devices
Atom-cavity quantum interface
The goal of this project is to develop an atom-cavity quantum network node. Planned research topics include:
Atom-photon entanglement at high fidelities
Reversible coherent state transfer between single atoms and photons
Implementation of quantum network protocols
Monitoring and stabilizing a qubit state via weak measurements
