Equilibrium thermometry in the multilevel quantum Rabi model
Tabitha Doicin, Luis A. Correa, Jonas Glatthard +2
The temperature sensitivity of a probe in equilibrium can be gauged by its thermal quantum Fisher information (QFI). It is known that probes exhibiting degeneracy in their energy-l…
Thermal-fluctuator driven decoherence of an oscillator resonantly coupled to a two-level system
Thomas J. Antolin, Jonas Glatthard, Andrew D. Armour
Recent experiments on a range of engineered quantum systems have highlighted the important role of interacting two-level systems (TLSs) in modifying device properties and generatin…
Quantum-corrected Floquet dynamics: bridging fully quantum and semiclassical regimes
E. K. Twyeffort, A. D. Armour
Semiclassical descriptions of a few-level system coupled to an electromagnetic field mode reduce the field to a time-dependent driving term. Although such methods are widely used,…
Quantitative calibration of a TWPA applied to an optomechanical platform
Alexandre Delattre, Ilya Golokolenov, Richard Pedurand +11
In the last decade, the microwave quantum electronics toolbox has been enriched with quantum-limited detection devices such as Traveling Wave Parametric Amplifiers (TWPAs). The ext…
Multilevel Quantum Rabi Models
Tabitha Doicin, Andrew D. Armour, Tommaso Tufarelli
The quantum Rabi model, which describes the interaction between a simplified atom and a mode of the electromagnetic field, is a cornerstone of modern quantum optics. One of the key…
