Geodesic-based optimal control for leakage suppression in superconducting qubits
Adonai Hilário da Silva, Tanmoy Pandit, Francesco Cosco
Superconducting qubits are often based on the first two energy levels of a physical anharmonic LC oscillator. Since the anharmonicity of such systems is usually much lower than the…
Even Odd Splitting of the Gaussian Quantum Fisher Information: From Symplectic Geometry to Metrology
Kaustav Chatterjee, Tanmoy Pandit, Varinder Singh +2
We introduce a canonical decomposition of the quantum Fisher information (QFI) for centered multimode Gaussian states into two additive pieces: an even part that captures changes i…
Fundamental Limitations on the Reliabilities of Power and Work in Quantum Batteries
Brij Mohan, Tanmoy Pandit, Maciej Lewenstein +1
Quantum batteries, microscopic devices designed to address energy demands in quantum technologies, promise high power during charging and discharging processes. Yet their practical…
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…
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…
Over-rotation coherent error induced by pseudo-twirling of quantum gates
Tanmoy Pandit, Raam Uzdin
Quantum error mitigation schemes (QEM) have greatly enhanced the performance of quantum computers, mostly by reducing errors caused by interactions with the environment. Neverthele…
Causal and Non-Causal Revivals of Information: A New Regime of Non-Markovianity in Quantum Stochastic Processes
Francesco Buscemi, Rajeev Gangwar, Kaumudibikash Goswami +5
The study of information revivals, witnessing the violation of certain data-processing inequalities, has provided an important paradigm in the study of non-Markovian quantum stocha…
Coherent heat transfer leads to genuine quantum enhancement in the performances of continuous engines
Brij Mohan, Rajeev Gangwar, Tanmoy Pandit +3
Conventional continuous quantum heat engines with incoherent heat transfer perform poorly as they exploit two-body interactions between the system and hot or cold baths, thus havin…
Squashed quantum non-Markovianity: a measure of genuine quantum non-Markovianity in states
Rajeev Gangwar, Tanmoy Pandit, Kaumudibikash Goswami +2
Quantum non-Markovianity in tripartite quantum states represents a correlation between systems and when conditioned on the system and is known to have both cl…
The asymmetric Otto engine: frictional effects on performance bounds and operational modes
Varinder Singh, Vahid Shaghaghi, Tanmoy Pandit +3
We present a detailed study of an asymmetrically driven quantum Otto engine with a time-dependent harmonic oscillator as its working medium. We obtain analytic expressions for the…
Steady-state Quantum Thermodynamics with Synthetic Negative Temperatures
Mohit Lal Bera, Tanmoy Pandit, Kaustav Chatterjee +4
A bath with a negative temperature is a subject of intense debate in recent times. It raises fundamental questions not only on our understanding of negative temperature of a bath i…
Probing The Unitarity of Quantum Evolution Through Periodic Driving
Alaina M. Green, Tanmoy Pandit, C. Huerta Alderete +2
As quantum computers and simulators begin to produce results that cannot be verified classically, it becomes imperative to develop a variety of tools to detect and diagnose experim…
Bounds on the recurrence probability in periodically-driven quantum systems
Tanmoy Pandit, Alaina M. Green, C. Huerta Alderete +2
Periodically-driven systems are ubiquitous in science and technology. In quantum dynamics, even a small number of periodically-driven spins leads to complicated dynamics. Hence, it…
