Characterizing quantum precision enhancement for multiple currents in open quantum systems
Khalak Mahadeviya, Sheikh Parvez Mandal, Mahasweta Pandit +3
The kinetic uncertainty relation (KUR) constrains fluctuations of individual currents in classical nonequilibrium systems in terms of the dynamical activity, which quantifies the a…
Bath memory as a precision resource in quantum transport
José Molina, Sheikh Parvez Mandal, Mahasweta Pandit +1
Structured baths can reshape transport fluctuations in mesoscopic quantum devices, yet a predictive criterion for when this enhances precision has been lacking. We propose a route…
Autonomous oscillations in quantum electromechanics: tensor network treatment
Mahasweta Pandit, Sheikh Parvez Mandal, Mark T. Mitchison +1
Transport-induced self-sustained oscillations in electromechanical systems convert a static electrochemical bias into robust, autonomous oscillatory motion in the absence of any ex…
Remote predictability of quantum measurement outcomes
Chirag Srivastava, Aparajita Bhattacharyya, Sheikh Parvez Mandal +2
Predicting quantum measurement outcomes for a local observer makes sense before, but not after, the measurement. However, for a remote observer, predicting measurement outcomes eve…
Current fluctuations in nonequilibrium open quantum systems beyond weak coupling: a reaction coordinate approach
Khalak Mahadeviya, Saulo V. Moreira, Sheikh Parvez Mandal +3
We investigate current fluctuations in open quantum systems beyond the weak-coupling and Markovian regimes, focusing on a coherently driven qubit strongly coupled to a structured b…
Heat operator approach to quantum stochastic thermodynamics in the strong-coupling regime
Sheikh Parvez Mandal, Mahasweta Pandit, Khalak Mahadeviya +2
Heat exchanged between an open quantum system and its environment exhibits fluctuations that carry crucial signatures of the underlying dynamics. Within the well-established two-po…
Quantum search in a non-Markovian environment
Sheikh Parvez Mandal
This MS thesis explores the effects and origins of a 'noise with memory' in the dynamics of an open quantum system. The system considered here is a multi-qubit register performing…
Invariance of success probability in Grover's quantum search under local noise with memory
Sheikh Parvez Mandal, Ahana Ghoshal, Chirag Srivastava +1
We analyze the robustness of Grover's quantum search algorithm performed by a quantum register under a possibly time-correlated noise acting locally on the qubits. We model the noi…
