Ancilla mediated steady-state engineering in open quantum systems
Soham Pal, Karen Hovhannisyan, Omri Porat +3
Engineering the properties of a reservoir and its coupling to a quantum system is a powerful tool for simulating quantum thermodynamic processes and for generating otherwise inacce…
Autonomous conversion of particle-exchange to quantum self-oscillations
Sofia Sevitz, Federico Cerisola, Karen V. Hovhannisyan +1
Particle-exchange machines utilize electronic transport to continuously transfer heat between fermionic reservoirs. Here, we couple a quantum mechanical resonator to a particle-exc…
Concentration of ergotropy in many-body systems
Karen V. Hovhannisyan, Rick P. A. Simon, Janet Anders
Ergotropy -- the maximal amount of unitarily extractable work -- measures the ``charge level'' of quantum batteries. We prove that in large many-body batteries ergotropy exhibits a…
Adaptive, symmetry-informed Bayesian metrology for precise quantum technology measurements
Matt Overton, Jesús Rubio, Nathan Cooper +4
High precision measurements are essential to solve major scientific and technological challenges, from gravitational wave detection to healthcare diagnostics. Quantum sensing deliv…
Correlations enable lossless ergotropy transport
Rick P. A. Simon, Janet Anders, Karen V. Hovhannisyan
"A battery powers a device" can be read as "work stored in the battery is being transported to the device." In quantum batteries, the total amount of stored work can be measured by…
