Quantum Journal Club: Tunable Superconducting Qubits with Flux-Independent Coherence
Abstract: We have studied the impact of low-frequency magnetic flux noise upon superconducting transmon qubits with various levels of tunability. We find that qubits with weaker tunability exhibit de...

Unconventional Bose-Einstein condensation beyond the no-node paradigm
Abstract: Feynman's "no-node" theorem states that the conventional many-body ground state wavefunctions of bosons in the coordinate representation are positive de nite. This implies that time-reversa...

Quantum Journal Club: Quantum Rabi Model with Trapped Ions
Abstract: We propose the quantum simulation of the quantum Rabi model in all parameter regimes by means of detuned bichromatic sideband excitations of a single trapped ion. We show that current setup...
