Two-dimensional Lattice Gauge Theories with Superconducting Quantum Circuits
D. Marcos, P. Widmer, E. Rico +4
A quantum simulator of U(1) lattice gauge theories can be implemented with superconducting circuits. This allows the investigation of confined and deconfined phases in quantum link…
Implementation of the Dicke lattice model in hybrid quantum system arrays
Liujun Zou, David Marcos, Sebastian Diehl +4
Generalized Dicke models can be implemented in hybrid quantum systems built from ensembles of nitrogen-vacancy (NV) centers in diamond coupled to superconducting microwave cavities…
Non-Markovian effects in the Quantum noise of interacting nanostructures
D. Marcos, C. Emary, T. Brandes +1
We present a theory of finite-frequency noise in non-equilibrium conductors. It is shown that Non-Markovian correlations are essential to describe the physics of quantum noise. In…
Observation of the Bloch-Siegert Shift in a Qubit-Oscillator System in the Ultrastrong Coupling Regime
P. Forn-Díaz, J. Lisenfeld, D. Marcos +4
We measure the dispersive energy-level shift of an resonator magnetically coupled to a superconducting qubit, which clearly shows that our system operates in the ultrastrong c…
