Non-Gaussian Dissipative Quantum Thermometry Beyond Gaussian Bounds
Pritam Chattopadhyay
The fundamental metrological limits of temperature sensing in open quantum systems remain largely unresolved, particularly regarding the role of non-Gaussian quantum resources. In…
Relativistic Quantum Otto Engine: Generalized efficiency bounds and frictional effects
Vahid Shaghaghi, Pritam Chattopadhyay, Vijit V. Nautiyal +3
This work investigates a relativistic quantum Otto engine with a harmonic oscillator as its working medium, analyzing how relativistic motion and nonadiabatic driving affect its pe…
Relativistic Quantum Thermal Machine: Harnessing Relativistic Effects to Surpass Carnot Efficiency
Tanmoy Pandit, Pritam Chattopadhyay, Kaustav Chatterjee +1
We investigate a three-level maser quantum thermal machine in which the system-reservoir interaction is modeled via Unruh-DeWitt type coupling, with one or both reservoirs undergoi…
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…
Landauer Principle and Thermodynamics of Computation
Pritam Chattopadhyay, Avijit Misra, Tanmoy Pandit +1
According to the Landauer principle, any logically irreversible process accompanies entropy production, which results in heat dissipation in the environment. Erasing of information…
Generic Two-Mode Gaussian States as Quantum Sensors
Pritam Chattopadhyay, Saikat Sur, Jonas F. G. Santos
Gaussian quantum channels constitute a cornerstone of continuous-variable quantum information science, underpinning a wide array of protocols in quantum optics and quantum metrolog…
