Exponentially enhanced two-mode multiboson entanglement via phase-modulated tunneling
Pritam Chattopadhyay, A. G. Kofman, Gershon Kurizki
The entanglement of quantum systems is commonly restricted by their coupling Hamiltonian and initial state properties. Here, we prove by exact analysis of tunnel-coupled bosonic fi…
Sensing microscopic noise events by frequent quantum measurements
Salvatore Virzì, Laura T. Knoll, Alessio Avella +8
We propose and experimentally demonstrate a general method allowing us to unravel microscopic noise events that affect a continuous quantum variable. Such unraveling is achieved by…
Nonlinear coherent heat machines and closed-system thermodynamics
Tomáš Opatrný, Šimon Bräuer, Abraham G. Kofman +5
All existing heat machines are dissipative open systems. Hence, they cannot operate fully coherently. We propose to replace this conventional thermodynamic paradigm by a completely…
Quantum Zeno and Anti-Zeno probes of noise correlations in photon polarisation
Salvatore Virzi', Alessio Avella, Fabrizio Piacentini +8
We experimentally demonstrate, for the first time, noise diagnostics by repeated quantum measurements. Specifically, we establish the ability of a single photon, subjected to rando…
Anti-Zeno quantum advantage in fast-driven heat machines
Victor Mukherjee, Abraham G. Kofman, Gershon Kurizki
Developing quantum machines which can outperform their classical counterparts, thereby achieving quantum supremacy or quantum advantage, is a major aim of the current research on q…
Quantum engine efficiency bound beyond the second law of thermodynamics
Wolfgang Niedenzu, Victor Mukherjee, Arnab Ghosh +2
According to the second law, the efficiency of cyclic heat engines is limited by the Carnot bound that is attained by engines that operate between two thermal baths under the rever…
