Heat, work, and fluctuations in a driven quantum resonator
Riya Baruah, Pedro Portugal, Jun-Zhe Chen +2
A central building block of a heat engine is the working fluid, which mediates the conversion of heat into work. In nanoscale heat engines, the working fluid can be a quantum syste…

Fast, high-fidelity Transmon readout with intrinsic Purcell protection via nonperturbative cross-Kerr coupling
Guillaume Beaulieu, Jun-Zhe Chen, Marco Scigliuzzo +5
Dispersive readout of superconducting qubits relies on a transverse capacitive coupling that hybridizes the qubit with the readout resonator, subjecting the qubit to Purcell decay…
