Criticality of environmental information obtainable by dynamically controlled quantum probes
Analia Zwick, Gonzalo A. Alvarez, Gershon Kurizki
A universal approach to decoherence control combined with quantum estimation theory reveals a critical behavior, akin to a phase transition, of the information obtainable by a qubi…
Thermal Baths as Quantum Resources: More Friends than Foes?
Gershon Kurizki, Ephraim Shahmoon, Analia Zwick
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their a…
Performance limits of multilevel and multipartite quantum heat machines
Wolfgang Niedenzu, David Gelbwaser-Klimovsky, Gershon Kurizki
We present the general theory of a quantum heat machine based on an -level system (working medium) whose excited levels are degenerate, a prerequisite for steady-state int…
On the operation of machines powered by quantum non-thermal baths
Wolfgang Niedenzu, David Gelbwaser-Klimovsky, Abraham G. Kofman +1
Diverse models of engines energised by quantum-coherent, hence non-thermal, baths allow the engine efficiency to transgress the standard thermodynamic Carnot bound. These transgres…
Maximizing information on the environment by dynamically controlled qubit probes
Analia Zwick, Gonzalo A. Alvarez, Gershon Kurizki
We explore the ability of a qubit probe to characterize unknown parameters of its environment. By resorting to quantum estimation theory, we analytically find the ultimate bound on…
Multiatom Quantum Coherences in Micromasers as Fuel for Thermal and Nonthermal Machines
Ceren B. Dağ, Wolfgang Niedenzu, Özgür E. Müstecaplıoğlu +1
In this paper we address the question: To what extent is the quantum state preparation of multiatom clusters (before they are injected into the microwave cavity) instrumental for d…
