Radiative Properties of an Artificial Atom coupled to a Josephson Junction Array
We study the radiative properties — the Lamb shift, Purcell decay rate and the spontaneous emission dynamics — of an artificial atom coupled to a long, multimode cavity
Protection of quantum information in a chain of Josephson junctions
Symmetry considerations are key towards our understanding of the fundamental laws of Nature. The presence of a symmetry implies that a physical system is invariant under specific transformations

Co-Designed Architectures for Modular Superconducting Quantum Computers
Noisy, Intermediate Scale Quantum (NISQ) computers have reached the point where they can show the potential for quantum advantage over classical computing. Unfortunately, NISQ machines
Fast high-fidelity composite gates in superconducting qubits: Beating the Fourier leakage limit
We present a method for quantum control in superconducting qubits, which overcomes the Fourier limit for the gate duration imposed by leakage to upper states. The method uses composite
