Here is a brief overview of our main research themes. More will come as the lab grows.
Storing and Processing Quantum States in Superconducting Circuits

Our main experimental platforms are superconducting quantum circuits. Combining Josephson junctions (or other elements that provide low-loss nonlinearity) with microwave resonators in the microwave domain allows us to perform cavity QED experiments with electrical circuits (“circuit QED”). We use these systems to realize quantum memories and processors.
Quantum Networks and Modular Quantum Computing

We are interested in building quantum links between small quantum systems (such as superconducting qubits or cavities) that are located on different chips. These links can, for example, work through microwave photons that propagate through low-loss cables. Connecting quantum processors in that way will be in an important ingredient for scaling up to very large quantum systems. These experiments also allow us to study quantum error correction (and related concepts, such as quantum state stabilization and entanglement distillation) in the context of quantum communication protocols.
Hybrid Quantum Circuits

Combining superconducting circuits with other degrees of freedom (such as electron spin or charge in semiconductors, or trapped spins in insulating crystals) has the potential to realize more powerful circuits. For example, accessing spins could provide very long memory lifetimes. Accessing charge in semiconductors could allow reading out different kinds of qubits. We are interested in building interfaces to realize such novel types of quantum devices.
