Superconducting Circuit Processor Architecture

About

The research group Superconducting circuit processor architecture studies strategies for implementing, controlling, and optimizing quantum operations on noisy intermediate-scale quantum devices based on circuit quantum electrodynamics.

Research Topics

We focus on existing hardware to characterize the dominant sources of coherent and incoherent errors and develop strategies to correct them, thereby improving single- and multi-qubit/qudit gates. Additionally, we use automated circuit discovery to find novel circuit architectures that exhibit noise protection while maintaining a high degree of control.

Our research activities are supported by semi-analytical and numerical methods, including perturbative diagonalization, shortcuts to adiabaticity, optimization through reverse engineering powered by automatic differentiation, and supervised and reinforcement learning agents for gate optimization, circuit compilation, and transpilation. Using these methods, we test our optimal solutions on available quantum hardware.
