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…
Quantum state localization in dipole-dipole interacting disordered networks
Pritam Chattopadhyay, Saikat Sur, Avijit Misra +3
We study the localization of excitations in positionally disordered spin or atom networks coupled via the realistic resonant dipole-dipole interaction (RDDI), which does not confor…
Molecular Processes as Quantum Information Resources
Saikat Sur, Pritam Chattopadhyay, Gershon Kurizki
In this contribution to Abraham Nitzan's Festschrift, we present a perspective of theoretical research over the years that has pointed to the potential of molecular processes to ac…
Sensing multiatom networks in cavities via photon-induced excitation resonance
Pritam Chattopadhyay, Avijit Misra, Saikat Sur +2
We explore the distribution in space and time of a single-photon excitation shared by a network of dipole-dipole interacting atoms that are also coupled to a common photonic field…
Quantum Transport Protected by Acceleration From Nonadiabaticity and Dissipation
Arnab Chakrabarti, Biswarup Ash, Igor Mazets +2
We put forth a hitherto unexplored control strategy that enables high-fidelity fast transport of an unstable quantum wavepacket even in the presence of bath-induced dissipation. Th…
Nonlinearity and Quantumness in Thermodynamics: From Principles to Technologies
Gershon Kurizki, Nilakantha Meher, Tomáš Opatrný
The impact of quantum mechanics on thermodynamics, particularly on the principles and designs of heat machines (HM), has been limited by the incompatibility of quantum coherent evo…
