Quantum Journal Club: Entanglement of Light-Shift Compensated Atomic SpinWaves with Telecom Light
Abstract: Entanglement of a 795 nm light polarization qubit and an atomic Rb spin-wave qubit for a storage time of 0.1 s is observed by measuring the violation of Bell’s inequality (S ¼ 2:65 0:12)...

Quantum Journal Club: Description of quantum coherence in thermodynamic processes requires constraints beyond free energy
Abstract: Recent studies have developed fundamental limitations on nanoscale thermodynamics, in terms of a set of independent free energy relations. Here we show that free energy relations cannot pro...

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...
