Dynamically enhancing qubit-photon interactions with antisqueezing

M Villiers, WC Smith, A Petrescu, A Borgognoni… - PRX Quantum, 2024 - APS
The interaction strength of an oscillator to a qubit grows with the oscillator's vacuum field
fluctuations. The well-known degenerate parametric oscillator has revived interest in the …

Graph theoretic analysis of three-terminal quantum dot thermocouples: Onsager relations and spin-thermoelectric effects

N Gupt, S Ghosh, A Ghosh - Physical Review B, 2024 - APS
We introduce a simplified model for a three-terminal quantum thermocouple consisting of
two strongly coupled quantum dots. To elucidate spin-dependent Seebeck and Peltier …
