In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

The robust generation of quantum states in the presence of decoherence is a primary
challenge for explorations of quantum mechanics at larger scales. Using the mechanical …

We demonstrate a trapped-ion system with two competing dissipation channels,
implemented independently on two ion species cotrapped in a Paul trap. By controlling …

We characterize topological phases in photonic lattices by unveiling a formal equivalence
between the singular value decomposition of the non-Hermitian coupling matrix and the …

We present a topological approach to the input-output relations of photonic driven-
dissipative systems acting as directional amplifiers. Our theory relies on a map** from the …

We study the performance of a single qubit laser as a quantum sensor to measure the
amplitude and phase of a driving field. By using parameter estimation theory we show that …

We investigate the nonequilibrium dynamics of a Josephson-coupled Jaynes-Cummings
dimer in the presence of Kerr nonlinearity, which can be realized in the cavity and circuit …

We propose a reliable scheme to realize the ultrastrong Jaynes-Cummings (JC) model by
simultaneously modulating the resonance frequencies of the two-level system and the …

As superconductor quantum technologies are moving towards large-scale integrated
circuits, a robust and flexible approach to routing photons at the quantum level becomes a …

We introduce a novel reservoir engineering approach for stabilizing multi-component Schr\"
odinger's cat manifolds. The fundamental principle of the method lies in the destructive …
